The diverse capabilities of self‐propelled micro/nanomotors open up significant opportunities for various environmental and biomedical applications. Here, a synchronized two‐lobed bubble exhaust drives micromotor comprising a metal (cobalt and gold) sandwiched polytryptophan body (Au/poly‐Trp/Co) in a non‐curved direction. The autonomous motion is achieved through the decomposition of chemical fuel to result in a kayak‐like system. The ejected oxygen bubbles from the interfacial cobalt/polytryptophan layer, as well as the inert nature of the metal segments (Au−Co), were considered for some computational studies of the electronic properties of the composite and physical phenomena at the kayak/electrolyte interfaces, and confirmed the role of Co−Trp in the fuel decomposition. It is believed that the autonomous motion is the combined result of bubble recoil force, self‐electrophoresis, and perturbation in the interfacial hydrogen‐bond network of the poly‐Trp body and water molecules. The velocity of the micromotor in the range 23±4 to 157±17 μm s⁻¹ at different concentrations of H₂O₂ from 1 % to 10 %. Depending on the method of fragmentation, it is possible to have both single and multiple motorized kayaks with lengths of 1.5 and 6 μm, respectively, that can be tailored for environmental applications.

基于金属夹心多色氨酸体的模板少自走式微电机的制造：实验和DFT研究。

自行式微型/纳米电动机的多种功能为各种环境和生物医学应用提供了巨大的机遇。在此，一个同步的两瓣式气泡排气驱动微电机，该微电机包含一个金属（钴和金）夹在非弯曲方向上的多色氨酸体（Au / poly-Trp / Co）。自主运动是通过分解化学燃料来实现的，从而形成皮划艇般的系统。考虑从复合材料的电子性能和皮划艇/电解质界面的物理现象的一些计算研究中考虑了从界面钴/多色氨酸层喷射的氧气气泡以及金属链段的惰性（Au-Co） ，并确认了Co-Trp在燃料分解中的作用。可以认为，自主运动是气泡反冲力，自电泳和多Trp体与水分子的界面氢键网络中的扰动的综合结果。微电机的速度范围为23±4到157±17μms^-1在不同浓度为h ₂ ö ₂从1％至10％。根据破碎方法的不同，有可能分别有长度为1.5和6μm的单个和多个电动皮划艇，可以针对环境应用进行定制。
