CuO/WO3 nanoparticles decorated graphene oxide nanosheets with enhanced peroxidase-like activity for electrochemical cancer cell detection and targeted therapeutics

The novel method was developed for electrochemical cancer cell detection using CuO/WO3 nanoparticle decorated graphene oxide nanosheet (CuO/WO3-GO) with enhanced peroxidase like-activity, based on catalytic reaction of H2O2 with o-Phenylenediamine (OPD). The prepared nanocomposite conjugated with folic acid (FA), as a cancer cell-targeting ligand, and a miniaturized electrochemical cell for cancer cell detection was designed. In this strategy...
