Rapid synthesis of self-propelled tubular micromotors for “ON–OFF” fluorescent detection of explosives

Abstract

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.
