Outline Activities
We have been developing general procedures to create synthetic nano materials, that function as antibody and enzymes, from inexpensive and stable acrylic monomers.

1, Development of Plastic Antibodies
General procedures for the creation of synthetic nanoparticles with biomacromolecular recognition sites are of significant interest as a route to stable, robust, and mass-produced substitutes for antibodies. Ideally, recognition of complex biological targets, including proteins, peptides, and carbohydrates, requires multiple functional groups that contact target molecules by a combination of electrostatic, hydrogen-bonding, van der Waals, and/or hydrophobic interactions. We have shown that copolymerization of optimized combination and ratio of functional acrylic-monomers creates synthetic polymer materials with molecular recognition sites for peptides and proteins. In addition to optimizing functional complementarity, the affinity sites can be further enhanced by molecular imprinting and/or affinity purification process. Those particles are capable of recognizing, neutralizing, and clearing toxic peptide and proteins even in the bloodstream of living animals. However, in contrast to antibodies whose exact sequence can be determined and cloned, polymerized materials result in heterogeneous structures with a distribution of recognition sites. Our goal is to achieve general strategy to create plastic antibodies with uniform molecular structure as "monoclonal plastic antibodies".


2, Development of Plastic Enzymes
Life is a dissipate structure appears in the non-equilibrium open system. To maintain the structure, enzymes mediates most reactions in the body including molecular transportation, energy conversion and molecular conversion that are necessarily for the life. To keep the life alive, it is important for the each enzyme to recognize and bind to specific molecules and ions and catalyze specific reaction just in time. It is also very important to control binding and dissociating kinetics to keep the dissipate structure.
One of the challenges for us is to construct synthetic molecular system like living life. So far, we found that target binding and dissociation kinetics of nanoparticles can be tuned by conformation change and polymer density of the particles. Binding constant to target proteins and ions can be reversibly switched on/off by temperature-induced phase transition of the polymer chains. By applying the fundamental findings, we are trying to develop inexpensive and scalable chemical process for the conversion of low temperature waste heat in to reusable chemical potential.

Yu Hoshino, Shohei Taniguchi,Hinata Takimoto, Sotaro Akashi, Sho Katakami, Yusuke Yonamine, Yoshiko Miura, Homogeneous Oligomeric Ligands Prepared via Radical Polymerization thatRecognize and Neutralize a Target Peptide, Angew. Chem. Int. Ed, doi.org/10.1002/anie.201910558, 132, 689-693, 2020.02, Abiotic ligands that bind to specific biomolecules have attracted attention as substitutes for biomolecular ligands, such as antibodies and aptamers. 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..

Unfortunately, conventional technologies are limited in uncovering these relations. We present a machine-intelligence technology based on a radically different architecture that realizes real-time image-based intelligent cell sorting at an unprecedented rate. This technology, which we refer to as intelligent image-activated cell sorting, integrates high-throughput cell microscopy, focusing, and sorting on a hybrid software-hardware data-management infrastructure, enabling real-time automated operation for data acquisition, data processing, decision-making, and actuation. We use it to demonstrate real-time sorting of microalgal and blood cells based on intracellular protein localization and cell-cell interaction from large heterogeneous populations for studying photosynthesis and
atherothrombosis, respectively. The technology is highly versatile and expected to enable machinebased scientific discovery in biological, pharmaceutical, and medical sciences..

Recently, we revealed that pNIPAm-based NPs that show large and　reversible pKa shifts can be prepared by the “proton imprinting” and　“microenvironment imprinting” strategy. The pKa variation range of　carboxylic acids in the NPs can further be tuned by designing structure of monomers　containing Brønsted acids and tuning cross-linking density and size of NPs. The pKa　variation range can be lowered/raised to be 4-9 by stabilizing/destabilizing carboxylate　anions by modifying the acids with electron withdrawing/donating group. The pKa of　acids can also be lowered dramatically by imprinting cationic functional group such as　guanidium group around the carboxylate anions.
Our results provide a guide for designing stable and inexpensive materials for many　biological and chemical applications as temperature-dependent affinity media and pH　modifiers..
