We have prepared Pt/Fe- and Fe-nanoparticle-labeled graphene sheets and demonstrate that these sheets can be detected by using impact electrochemistry through oxygen reduction mediation.
Self-propelled micromotors, as the next frontier of smart miniaturized machines, are able to carry out a plethora of tasks and operations. To date, the evaluation of their capabilities and behavior has been carried out by optical microscopy coupled with computationally intensive imaging software. The use of particle-electrode impact voltammetry serves as an alternative means of …
