| Abstract |
界面活性剤水溶液中を自発的に動くマイクロメートルサイズの油滴を用いて, 電場や磁場などの動力源なしに, 化学物質を目的の場所に送達する省エネルギー型の輸送担体へと応用することを目指した。油滴をpH勾配下においたり, 油滴に一方向から光を照射したりすると, それらに応答して特定の方向に動くことがわかった。これは, 界面活性剤や油の成分がそれら外部からの刺激によって変化したためと考えられ, 油滴が動く方向を正確に制御する上で重要な知見が得られた。
This study aimed to apply micrometer-sized oil droplets that move spontaneously in the surfactant aqueous solution to energy-saving transport carriers that deliver chemical substances to target locations without using a power source, such as an electric field and a magnetic field. It was found that oil droplets under a pH gradient and light-irradiated oil droplets moved in a specific direction in response to them. This is because the components of the surfactant and oil are changed by such stimulations. Therefore, the important knowledge was obtained for accurately controlling the direction of oil droplet movement.
