Abstract
We demonstrate the phototactic behavior of self-propelled micrometer-sized oil droplets in the presence of azobenzene-containing surfactants. These droplets respond sensitively to UV light irradiation due to a variation in the interfacial tension at the droplet surface induced by the molecular conversion of the azobenzene-containing surfactants.
摘要
我们展示了在含偶氮苯表面活性剂存在下，自行推进的微米级油滴的光趋性。由于含偶氮苯表面活性剂的分子转化引起液滴表面界面张力的变化，这些液滴对紫外线照射敏感响应。
