Outline Activities
[ Research Activities]
Based on polymeric materials, chemical engineering, biopolymers, and interface science, I am conducting the following research.
(1)Biounctional materials with glycopolymers
Glycans on the cell surface act as signal molecules for life. Polymers with these attached to their side chains are polymeric materials that emit the molecular recognition ability of glycans. By designing sugar chains in various ways, it is possible to create polymers that efficiently cause recognition of various biomolecules such as cells, viruses, and toxin proteins.
In the synthesis of glycopolymers, vinyl compounds to which sugar chains are attached can be linked to precise materials and composite materials using polymer synthesis chemistry. Especially in recent years, precision controlled polymerization such as living radical polymerization has been used to design precise binding to proteins and cells using precision polymers such as block polymers, star polymers, and nanogels. We are also developing syntheses that incorporate the latest polymerization, photopolymerization. By graft polymerization in combination with base materials, bio-recognitive materials and devices can be created, which can be used for materials to eliminate specific pathogens. It is also possible to develop molecules for controlling cellular immunity. In our group we are currently using these technologies to develop materials useful for medical devices and basic biology.

(2) Immobilized catalysts and new chemical synthesis processes using porous polymer materials
Immobilized catalysts are important in chemical processes, including organic synthesis, because of the easy separation of catalyst and substrate and their applicability to distribution processes. On the other hand, in the organic synthesis processes, immobilized catalysts have disadvantages in mass transfer compared to homogeneous catalysts. Therefore, in our group we are developing immobilized catalysts using porous materials that facilitate substrate mass transfer and have a large effective surface area. Porous polymer immobilized catalysts are prepared by microphase separation phenomena of polymers. Organometallic and molecular catalysts are used as catalysts. Porous polymers have high solution permeability, and accordingly, the mass transfer of substrates is good. In particular, we are investigating continuous- flow synthesis using porous polymer-immobilized catalysts.

(3) Polymer Functional Materials by Machine Learning
Polymers are a major component of soft matter and have a wide range of applications in chemistry, biotechnology, and materials. They are also important carbon neutral targets. The development of soft matter is a complex process that requires a great deal of human capital and time. This approach will be greatly modified to develop polymeric functional materials using methods that quickly optimize experimental results. The problem is how to data polymeric materials. Based on the method of developing functional polymers with copolymers that has been conducted in our laboratory, we are proceeding with learning using monomer ratios and the development of functional materials through this method. Through the research described in (2) above, we are also studying chemical processes that can lead to automated synthesis using flow synthesis.

Yoshiko Miura, Controlled Polymerization for the development of bioconjugate polymers and materials, Journal of Materials Chemistry B, 10.1039/C9TB02418B, 2020, 8, 2010-2019, 2020.01, Controlled polymerization through living radical polymerization is widely studied. Controlled polymerization enables synthetic polymers with precise structures, which have the potential for excellent bio-functional materials. This review summarizes the applications of controlled polymers, especially those via living radical polymerization, to biofunctional materials and conjugation with biomolecules. In the case of polymer ligands like glycopolymers, the polymers control the interactions with proteins and cells based on the precise polymer structures. Living radical polymerization enables the conjugation of polymers to proteins, antibodies, nucleic acids and cells. Those polymer conjugations are a sophisticated method to modify bio-organisms. The polymer conjugations expand the potential of biofunctional materials and are useful for understanding biology..

However, monomer sequences in the synthetic NPs are heterogeneous. The heterogeneity limits the target specificity and safety of the NPs. Herein, we report the synthesis of NPs with uniform monomer sequences for recognition and neutralization of target peptides. A multifunctional oligomer with a precise monomer sequence that recognizes the target peptide was prepared via cycles of reversible addition–fragmentation chain transfer (RAFT) polymerization and flash chromatography. The oligomer or blend of oligomers was used as a chain transfer agent and introduced into poly(N-isopropyl acrylamide) hydrogel NPs by radical polymerization. Evaluation of the interaction with the peptides revealed that multiple oligomers in NPs cooperatively recognized the sequence of the target peptide and neutralized its toxicity. Effect of sequence, combination, density and molecular weight distribution of precision oligomers on the affinity to the peptides was also investigated..

Herein, we demonstrate de novo design of star-shaped glycoligands to interact with hemagglutinin (HA) using well-defined synthetic polymers with the aim of developing an effective inhibitor for the influenza virus. Prior to the synthesis, the length of the star polymer chains was predicted using the Gaussian model of synthetic polymers, and the degree of polymerization required to achieve multivalent binding to three carbohydrate recognition domains (CRDs) of HA was estimated. The star polymer with the predicted degree of polymerization was synthesized by reversible addition–fragmentation chain transfer (RAFT) polymerization, and 6′-sialyllactose was conjugated as the glycoepitope for HA. The designed glycoligand exhibited the strongest interaction with HA as a result of multivalent binding. This finding demonstrated that the biological function of the synthetic polymer could be controlled by precisely defining the polymer structures..

Mater. Chem. B, 2022, 10, 2597-2601 10.1039/D1TB02344F (Paper), 2021.12, Carbohydrates on cell surfaces are known to interact not only with lectins but also with other carbohydrates; the latter process is known as a carbohydrate–carbohydrate interaction. Such interactions are observed in complex oligosaccharides. It would be surprising if these interactions were observed in simple monosaccharides of mannose. In this study, the interaction between glycopolymers carrying monosaccharides of mannose was quantitatively investigated by quartz crystal microbalance measurements. We measured the interactions with glycopolymers carrying mannose, galactose and glucose. Surprisingly, the interaction between the glycopolymers and mannose was much stronger than that between other saccharides..

Herein, we synthesized glycopolymers carrying 3′-sialyllactose in various glycounit densities. RAW 264.7 macrophages transfected to express secreted alkaline phosphatase (SEAP) were used to evaluate the immunosuppression ability of the glycopolymers. The inhibition of the signal transmission was dependent on the glycounit densities of the glycopolymers, and was maximized at the moderate density (70%)..

Chem. Eng., 2022, 7, 55-60, 2021.11, The effect of monolith structure and monolith reactor inner diameter on the residence time distribution (RTD), and the relationship between RTD and the catalytic efficiency of the asymmetric aldol addition reaction between p-nitrobenzaldehyde and cyclohexanone were examined. A monolith column containing L-proline as a catalyst was prepared using poly(ethylene glycol) (PEG) as the porogen. The monolith column prepared with PEG with a molecular weight of 6000 Da displayed a narrow pore size distribution and showed a controlled RTD. The performance of monolith reactors with different inner diameters (micro- and millireactors, 0.53 and 4.00 mm) was compared: the microreactor displayed a narrower RTD and a higher turnover number for the asymmetric aldol addition reaction than the millireactor. The different linear flow velocities in the microreactor did not affect the catalytic reaction efficiency and enantioselectivity, demonstrating that the RTDs can be controlled regardless of the flow velocity..

Benshuai Guo, Yoshiko Miura, Yu Hoshino, Rational Design of Thermocells Driven by the Volume Phase Transition of Hydrogel Nanoparticles, ACS Applied Materials & Interfaces, 10.1021/acsami.1c07266, 13, 27, 32184-32192, ACS Appl. Mater. Interfaces 2021, 13, 27, 32184–32192, 2021.10, Thermocells are thermoelectrochemical conversion systems for harvesting low-temperature thermal energy. Liquid-state thermocells are particularly desirable because of low cost and their high conversion efficiency at temperatures around physiological temperature, and they have, thus, been extensively studied. However, the performance of the thermocells has to be improved to utilize them as energy chargers and/or batteries. Recently, we reported that a liquid-state thermocell driven by the volume phase transition of hydrogel nanoparticles showed highly efficient thermoelectric conversion with Seebeck coefficient (Se) of −6.7 mV K–1. Here, we report the design rationale of the thermocells driven by the phase transition. A high Se of −9.5 mV K–1 was achieved at temperature between 36 and 40 °C by optimizing choice and amount of redox chemical species. The figure of merit (ZT) of the thermocell was improved by selecting appropriate electrolyte salt to increase the ionic conductivity and prevent the precipitation of nanoparticles. Furthermore, screening of nanoparticles revealed the high correlation between Se and the pH shift generated as a result of phase transition of the nanoparticles. After optimization, the maximum ZT of 8.0 × 10–2 was achieved at a temperature between 20 and 70 °C..

Commun., 2021, 57, 10871-10874, 2021.09, The “carbohydrate module method” is a promising approach for oligosaccharide mimetics using polymeric materials. However, it is difficult to predict the optimal structure for a particular oligosaccharide mimetic, and an efficient strategy for the synthesis and evaluation of glycopolymers is desirable. In this study, a screening of glycopolymers for the “carbohydrate module method” by a combination of photoinduced electron/energy transfer-reversible addition–fragmentation chain-transfer (PET-RAFT) polymerization and surface plasmon resonance imaging (SPRI) is demonstrated. The facile and fast screening of synthetic glycomimetics was achieved, and the glycopolymer with the optimal structure as a GM1 mimetic strongly interacted with the cholera toxin B subunit..

Monomer structures for synthetic biofunctional polymers are usually selected based on their compatibility with polymerization systems, whereas the influence of monomer structures on the interaction with target molecules is hardly considered. In this report, we evaluate the correlation between the monomer structures of glycopolymers and their interactions with concanavalin A (ConA) with respect to the molecular mobility. Two types of glycopolymers bearing mannose are synthesized with acrylamide or acrylate monomers. Despite the similar structures, except for amide or ester bonds in the side chains, the acrylate-type glycopolymers exhibit stronger interaction with ConA both in the isothermal titration calorimetry measurement and in a hemagglutination inhibition assay. Characterization of the acrylate-type glycopolymers suggests that the higher binding constant arises from the higher molecular mobility of mannose units, which results from the rotational freedom of ester bonds in their side chains..

Mater. Interfaces , 10.1021/acsami.1c06447, 13, 25, 30030-30038, ACS Appl. Mater. Interfaces 2021, 13, 25, 30030–30038, 2021.06, The development of robust and thin CO2 separation membranes that allow fast and selective permeation of CO2 will be crucial for rebalancing the global carbon cycle. Hydrogels are attractive membrane materials because of their tunable chemical properties and exceptionally high diffusion coefficients for solutes. However, their fragility prevents the fabrication of thin defect-free membranes suitable for gas separation. Here, we report the assembly of defect-free hydrogel nanomembranes for CO2 separation. Such membranes can be prepared by coating an aqueous suspension of colloidal hydrogel microparticles (microgels) onto a flat, rough, or micropatterned porous support as long as the pores are hydrophilic and the pore size is smaller than the diameter of the microgels. The deformability of the microgel particles enables the autonomous assembly of defect-free 30–50 nm-thick membrane layers from deformed ∼15 nm-thick discoidal particles. Microscopic analysis established that the penetration of water into the pores driven by capillary force assists the assembly of a defect-free dense hydrogel layer on the pores. Although the dried films did not show significant CO2 permeance even in the presence of amine groups, the permeance dramatically increased when the membranes are adequately hydrated to form a hydrogel. This result indicated the importance of free water in the membranes to achieve fast diffusion of bicarbonate ions. The hydrogel nanomembranes consisting of amine-containing microgel particles show selective CO2 permeation (850 GPU, αCO2/N2 = 25) against post-combustion gases. Acid-containing microgel membranes doped with amines show highly selective CO2 permeation against post-combustion gases (1010 GPU, αCO2/N2 = 216) and direct air capture (1270 GPU, αCO2/N2 = 2380). The membrane formation mechanism reported in this paper will provide insights into the self-assembly of soft matters. Furthermore, the versatile strategy of fabricating hydrogel nanomembranes by the autonomous assembly of deformable microgels will enable the large-scale manufacturing of high-performance separation membranes, allowing low-cost carbon capture from post-combustion gases and atmospheric air..

Radical polymerization enables the production of robust polymeric ligands from inexpensive functional monomers. However, little has been reported about the production of monodispersed polymeric ligands. Herein, we present homogeneous ligands prepared via radical polymerization that recognize epitope sequences on a target peptide and neutralize the toxicity of the peptide. Taking advantage of controlled radical polymerization and separation, a library of multifunctional oligomers with discrete numbers of functional groups was prepared. Affinity screening revealed that the sequence specificity of the oligomer ligands strongly depended on the number of functional groups. The process reported here will become a general step for the development of abiotic ligands that recognize specific peptide sequences..

A glycopolymer library was prepared to obtain guidelines for the design of glycopolymers for the recognition of cholera toxin B subunits (CTB). Glycopolymers with varying ratios of hydrophobic and sugar units were synthesized by reversible addition fragmentation chain transfer polymerization. N-tert-Butylacrylamide, N-phenylacrylamide, and N-cyclohexylacrylamide as hydrophobic units were copolymerized in the polymer backbone, and galactose, which contributes to CTB recognition, was introduced into the side chains by "post-click" chemistry. The thiol-terminated glycopolymers were immobilized on a gold surface. The polymer immobilization substrate was analyzed in terms of interaction with galactose recognition proteins (CTB, peanut agglutinin, and Ricinus communis agglutinin I) using surface plasmon resonance imaging. The polymers with high ratios of sugar and hydrophobic units had the strongest interactions with the CTB, which was different from the trend with peanut agglutinin and Ricinus communis agglutinin I. The binding constant of the CTB with the glycopolymer with hydrophobic units was 4.1 × 106 M-1, which was approximately eight times larger than that of the polymer without hydrophobic units. A correlation was observed between the log P value and the binding constant, indicating that the hydrophobic interaction played an important role in binding. New guidelines for the design of recognition materials were obtained by our screening method..

Multifunctional glycopolymers for molecular recognition were prepared via living radical polymerization and post-click chemistry with orthogonal Huisgen and thiol-epoxy reactions. The synthesis of the polymer backbone and the subsequent side-chain introduction successfully proceeded in high yield. The multifunctional glycopolymers had a tri-block structure: the first and third blocks contained mannose, and the second block contained either a positively or negatively charged group or a neutral hydrophilic group. The molecular recognition of the glycopolymers toward lectin was evaluated via fluorescence quenching measurements. Because of the electrostatic interaction, the binding constant varied in the following order: positively charged glycopolymer (PT110) > negatively charged glycopolymer (NT110). The effect of the electrostatic interactions was modest compared with the effect of the carbohydrate–lectin binding. These results suggested that the carbohydrate–lectin interaction was an important factor in the molecular recognition of glycopolymers. This study provides guidelines for the preparation of multifunctional polymers, such as biomaterials..

We report the topological design of glyco-ligands based on synthetic polymers for targeting hemagglutinin (HA, lectin on the influenza virus). To achieve precise arrangement of the glycounits toward the sugar-binding pockets of HA, triarm star glycopolymers were synthesized. The interaction of the star glycopolymers with HA was found to depend on the length of the polymer arms and was maximized when the hydrodynamic diameter of the star glycopolymer was comparable to the distance between the sugar-binding pockets of HA. Following the formula of multivalent interaction, the number of binding sites in the interaction of the glycopolymers with HA was estimated as 1.8–2.7. Considering one HA molecule has three sugar-binding pockets, these values were reasonable. The binding mode of synthetic glycopolymer–ligands toward lectins could be tuned using controlled radical polymerization techniques..

Moreover, PEGMA500-Phosmer and homoPhosmer coatings presented better responses to MC3T3-E1 preosteoblast cells when compared with the results for PEGMA2000-Phosmer-coated and raw Ti alloy surfaces. The behavior of balancing bacterial inhibition and cell attraction of the PEGMA500-Phosmer coating was explained by the grafted phosphate groups, with an appropriate PEG brush length facilitating greater levels of calcium deposition and further fibronectin adsorption when compared with that of the raw Ti alloy surface..

However, they often suffer from high cost, and difficulties in their development, production and storage. Here we show that a synthetic polymer nanoparticle (NP) can be engineered to have many of the functions of a protein affinity reagent. Polymer NPs with nM affinity to a key vascular endothelial growth factor (VEGF165) inhibit binding of the signalling protein to its receptor VEGFR-2, preventing receptor phosphorylation and downstream VEGF165-dependent endothelial cell migration and invasion into the extracellular matrix. In addition, the NPs inhibit VEGF-mediated new blood vessel formation in Matrigel plugs in vivo. Importantly, the non-toxic NPs were not found to exhibit off-target activity. These results support the assertion that synthetic polymers offer a new paradigm in the search for abiotic protein affinity reagents by providing many of the functions of their protein counterparts..

To investigate the multivalent effect, the use of multivalent compounds or “glycoclusters” is indispensable, and many groups have reported syntheses of glycocluster compounds. Examples of glycoclusters include liposomes with glycolipids, glycocalixarenes, glycocyclodextrins, glycopeptides, and glycopolymers. Among the various synthetic glycoclusters, glycopolymers have been the subject of much attention . In this review, we define glycopolymers as polymers carrying pendant saccharides. Since glycopolymers have larger valencies than other multivalent compounds, they show the largest amplification effects in molecular recognition. Glycopolymers are able to be prepared as nanomaterials by controlled polymerization. In this section of the review, we discuss glycopolymers and their application for biotechnology..

Xinnan Cui, Hirokazu Seto, Tatsuya Murakami, Yu Hoshino, Yoshiko Miura, Inhibition of Bacterial Adhesion on Hydroxyapatite Model Teeth by Surface Modification with PEGMA-Phosmer Copolymers, ACS Biomater. Sci. Eng, 10.1021/acsbiomaterials.5b00349, 2, 2, 205-212, 2016.02, Modification of the interface properties on hydroxyapatite and tooth enamel surfaces was investigated to fabricate bacterial resistance in situ. A series of copolymers containing pendants of poly(ethylene glycol) methyl ether methacrylate (PEGMA) and ethylene glycol methacrylate phosphate (Phosmer) were polymerized by conventional free radical polymerization and changing the feed ratio of monomers. The copolymers were immobilized on hydroxyapatite and tooth enamel via the affinity of phosphate groups to hydroxyapatite to form the stable and durable polymer brushes on the surfaces. The amounts of polymer immobilized depended on the phosphate group ratio in the copolymers. Surface modification altered the interfacial properties of hydroxyapatite and inhibited bacterial adhesion. Copolymers containing 40–60% PEGMA segments showed a significant inhibitory effect on bacterial adhesion of S. epidermidis both in the presence and absence of plaque model biomacromolecules..

Immobilization of the trimethoxysilane-containing copolymer on the matrices was readily performed by incubation at high heat. The recognition of lectin by poly(Man-r-TMS) was evaluated by measurement with a quartz crystal microbalance (QCM) and adsorption on an affinity membrane, QCM results showed that the mannose-binding protein, concanavalin A, was specifically bound on a poly(Man-r-TMS)-immobilized cell with a higher binding constant than bovine serum albumin. The amount of concanavalin A adsorbed during permeation through a poly(Man-r-TMS)-immobilized membrane was higher than that through an unmodified membrane. Moreover, the concanavalin A adsorbed onto the poly(Man-r-TMS)-immobilized membrane was recoverable by permeation of a mannose derivative at high concentration..
