We report the design of autonomous motors powered by the rapid depolymerization reaction of poly(2-ethyl cyanoacrylate) (PECA), an FDA-approved polymer. Motors were fabricated in two different length scales, 3 cm and 300 μm. The motion of the motors is induced by self-generated surface tension gradients along their bodies. The motors are capable of moving in various media, including salt solutions and artificial serum.
我们报告了由快速解聚反应驱动的自主马达的设计,该马达由聚(2-乙基氰基丙烯酸酯)(PECA)驱动,这是一种 FDA 批准的聚合物。马达在两种不同的长度尺度上进行制造,分别为 3 厘米和 300 微米。马达的运动是由其自身产生的表面张力梯度沿其体诱导的。这些马达能够在各种介质中运动,包括盐溶液和人工血清。
