Platinum-based micromotors have shown many exciting applications when functionalized using gold-thiol chemistry. However, thiols are known to bind to the Pt surface, which can lead to serious deactivation of the catalyst. In this paper, it is demonstrated that MnO2 can be used to protect Pt-based micromotors prior to the thiol treatment, thus fully avoiding the catalyst poisoning. This approach will greatly facilitate the use of the functionalized Pt micromotors for which the thiol toxicity has been a limiting factor.
