Abstract

Herein, we study the transport of cargo manipulation (loading and release) and self-propelling (Janus particle - JP) carrier, acting as a mobile microelectrode, is singularly controlled using an alternating current electric field. The underlying mechanism of the cargo manipulation was dielectrohporesis (DEP) which enabled selective and label-free loading and release by simply tuning the frequency. It is demonstrated that trapping is enabled via both negative and positive DEP with distinctly different trapping locations on the JP. In addition, magnetic steering enabled the study of the number of trapped cargo and the maximal loading as a function of the cargo size and electric field parameters.
