Bottom-up synthesis of multi-metal micro/nano motors

In the past two decades, micro/nano motors have experienced rapid development, especially in environment remediation, biomedical field, and cargo delivery. In this article, we synthesize a micro-nano motor composed of a variety of materials through the bottom-up method (template electrodeposition), and we use different functional layers and catalytic layers in the synthesis process. With this method, we test the motion effects of different materials in solution. In order to better analyze the influence of different factors on the motor movement effect, we mainly selected three factors to analyse from different aspects, respectively, hydrogen peroxide concentration, surfactant type, surfactant concentration. According to these statistical data, the movement efficiency and diversity of micromotors in different environments will be achieved.近二十年来，微/纳米电机（micro/nano motor）发展迅猛，尤其在环境修复、生物医学领域与货物递送场景中得到了广泛的研究与应用。本文采用自下而上法（bottom-up method），以模板电沉积法（template electrodeposition）作为具体合成路径，以多种材料合成了一款微纳米电机，并在合成过程中引入了不同功能层与催化层。基于该合成方法，我们测试了不同材料在溶液中的运动性能。为更深入剖析不同因素对电机运动性能的影响，我们主要选取三类影响因子从多维度展开分析，分别为过氧化氢浓度、表面活性剂种类以及表面活性剂浓度。基于上述统计数据，可明确不同环境下微纳米电机的运动效率与运动多样性特征。
