Abstract
Nano- and micromotors have emerged as promising platforms due to their ability to efficiently convert chemical energy into motion, mimicking the way nature uses biochemistry to power biological motors. These tiny devices hold significant potential for a range of environmental and biomedical applications. When nano- and micromotors are modified with conductive polymers, they become functional to target analytes and provide the opportunity for electrochemical determination of analytes due to their functionality. In this paper, a novel type of multifunctional tubular micromotor (pDM-Au-Ni) was designed to detect Zn(II) ions. The pDM-Au-Ni micromotor was functionalized with a fluorescent conductive polymer that was electrochemically synthesized from a dansyl chloride-based polycarbazole derivative (DM) which has specific groups (–NH, –CO) for the interaction of Zn(II). pDM-Au-Ni micromotor provided fast, effective detection based on fluorescence intensity, magnetic speed, and electrochemical changes. This is the first report on the integration of functional dansyl-polycarbazole conductive polymer to tubular magnetic micromotor for Zn(II) detection with multi-signal outputs.
