This technique uses the strong points of the powerful ablation of cavitation as well as plasma irradiation. The novelty of the technique enable to process not only conductive material but also non-conductive material such as polymer, CFRP (carbon fiber reinforced plastic) and silicon, which is unlike conventional wire electric discharge machine. Also, the directional transportation of bubbles provides positioning accuracy of micro-processing. The structure of the plasma-cavitation pencil cutter is low cost and very simple structure. This technology contributes to effective processing of wide range of materials such as metal plate, polymer, carbon-fiber and biomaterials.. |

The novelty of our work is collection and concentration of radical species and which is confirmed by ESR (Electron Spin Resonance) measurement. Formation of bubbles which has a relatively large surface area accelerates the production of radical species at air-liquid interface and these bubbles are concentrated by the circulating flow in the microfluidic chip.

When an electric charge is stored in the bipolar plate of a capacitor, an electrostatic force acts. We perform adhesion to a wall surface using this electrostatic force. Using the electrostatic force, electrostatic adhesion force is controlled by the electricity. The flexible electrodes are created by spraying a solution containing dispersed carbon black onto a silicon rubber. Flexibility of the device can avoid damage to its own and adapt to a variety of wall surface shapes. In experiments, two kinds of device surface structures were created. One is just flat and the other is pillar arrays. The pillar arrays structure was adopted from the viewpoint of biomimetic. Electrostatic adhesion force of these structures was measured with shear and tensile testing machines.. |

Kazuki Takahashi, Shun Omi, Yoko Yamanishi, Minimally-invasive local injection by electrically-driven narrow orifice channel, 2014 International Symposium on Micro-NanoMechatronics and Human Science, MHS 2014, 2015.01, We have successfully developed minimally-invasive needle-free bubble injector designed for the usage in air. The novelty is that the minimally-invasiveness of injection whose resolution is less than 10 μm, and hence cellular-scale injection can be possible without any pain. The novelty of the present techniques are (1) unique robust thick structure at the tip of the narrowed glass capillary for operation in air, (2) damper structure produce closed space to fill in reagent which enabled the injector to be used in air and (3) construction part to support inner probe to make self-aligned coaxial positioning for accurate injection. The injector can be used for any kind of materials with various hardness, owing to the strong impact of cavitation phenomenon when the high-speed micro-bubbles are collapsed. The fine adjustment of injection can be controlled by the number of applied electric pulses. The developed injector can be used for wide range of biomedical study, especially in gene therapy. This technique has advantages over the conventional electroporation or ultrasound operation in terms of localization of injection and ability of transportation of material.. |

The novelty of our work is separation and extraction of radical species from plasma irradiation and to produce reactive interface in micro-fluidic chip. It was also confirmed that several radicals species are detected by ESR (Electron Spin Resonance) measurement and the radical-induced protein crystal are produced for low concentration of protein. This microfluidic chip contributes to the protein crystal production and bio-medical applications.. |

High speed ejection of electrically driven mono-dispersed micro-bubbles enables to penetrate mother bubble, which forces to produce circulating motion in the bubble, and bubble rings are successfully produced. This is the new protocol to produce bubble ring in microfluidic environment for the first time. This micro-bubble ring carries a strong vortex characteristic which can contribute to efficient mixing in closed micro-space and also cleaning of micro-channel wall.. |

The air-liquid interfaces of the dispensed bubbles have novel characteristics which can carry the various kinds of the materials in different phase and viscosity of solution. This technique has advantages in high efficiency of injection of limited amount of valuable samples such as designed m-RNA. In this paper, we demonstrated m-RNA encoding 3xFLAG-GST into xenopus oocyte to be sure that electrically induced bubble knife has ability to injection chemically unstable and biocompatibility. Furthermore, we injected fluorescent beads whose size was 2.1 μm into BY-2 cell as multiphase injection.. |

The discharged output power and conductive area of micro-electrode in micro-bubble knife which cuts the cell by micro-bubble were controlled by glass shell insulation around the copper micro-wire. A small space which is called 'bubble reservoir' between the wire and glass tip contributes to stabilize the electric discharge and directional bubble generation. The directionally dispensed bubbles can be used for processing of soft materials such as biological cells. For the present study the cell membrane has successfully processed with a few μm order resolution.. |
