Outline of Final Research Achievements

Biological cell exhibits self-motility by chemical reactions with the surrounding chemicals. In this study, the amphiphilic molecular assemblies, that resembles biological cell, are exposed to a pH change. The chemical reactions cause the self-motion that induces convection around the molecular assembly. This is a molecular assembly pump that operates in micro-space. Recently, chemical systems with very small scale have attracted much attention for chemical analysis and synthesis. Numerous channels with micrometer scale are embedded in the small system. However, the micropumps that operates in the micro system have not fully been studied. In this study, we have designed a micropump made from amphiphilic molecules that operates by chemical reaction with the surrounding proton or hydroxide ion.
