We report a rapid strategy to construct self-propelled functional tubular micromotors. Based on the established strategy, magnetic covalent-organic-framework-functionalized micromotors were fabricated to implement sensing of explosives in water. Such micromotors can complete fluorescent “On–Off” detection of trace explosive 2,4,6-trinitrophenol within 10 min.

快速合成自走式管状微电机，用于炸药的“ON-OFF”荧光检测

我们报告了一种构建自走式功能管状微型电机的快速策略。基于既定策略，制造磁性共价有机框架功能化微电机以实现水中爆炸物的传感。这种微电机可以在 10 分钟内完成对痕量爆炸物 2,4,6-三硝基苯酚的荧光“开-关”检测。
