Outline of Final Research Achievements |
The future plan of this study is construction of highly portable microfluidic analytical system. For this goal, we have aimed at using self-propelled oil droplets in the system. When this analytical device is constructed with full comprehension about the mechanism of the self-propelled motion, it is worthwihle for the application of highly portable analytical device with less (or almost zero) external electric power. We found that the derivatives of water-insoluble benzaldehyde formed micrometer-sized oil droplets in a cationic surfactant solution which filled with a microfluidic chip and it exhibited self-propelled motion over 1 h. Moreover, the oil droplets had a potential to response to a gradient of the cationic surfactant concentration or chemical conversion of reactive surfactants.
