Recently, single particle analysis through electrochemical collision (i.e., nano-impact electrochemistry or single-entity electrochemistry) on ultramicroelectrodes has been actively studied. This single particle collision method is a great way to analyze diffusion coefficients, single particle compositions, size distribution of particle, concentrations, and diffusion behavior of particles in solution. Our group studied soft particles such as emulsions (water/oil and oil/water), bacteria, red blood cells and platelets by electrochemical single particle collision. These studies take advantage of the increase or decrease in the current signal that occurs when a single particle collides the electrode surface. The second topic is electroanalytical chemistry for polymers. Polymers are materials closely related to our daily life, but it is difficult to analyze through electroanalytic chemistry. These are because most polymers are electrochemically inactive materials. Our research group introduces new electroanalytic techniques that analyzes the properties of these electrochemically inactive polymers by using solution viscosity and the interaction of the electrochemically active redox species.
