Electrochemical characterization and DNA sensing application of a sphere-like CeO2–ZrO2 and chitosan nanocomposite formed on a gold electrode by one-step electrodeposition
A simple, safe, and efficient approach to synthesise graphene/titanium dioxide (G/TiO2) nanocomposites with potential in electrochemical sensing application and relatively good biocompatibility to human cells.
AuNPs(EDAS) – rGO nanocomposites were prepared by a facile one step sonochemical synthesis process. Here, EDAS acts as an interlinker for anchoring gold on rGO and it also acts both as a reducing agent and a stabilizing agent. The AuNPs(EDAS) – rGO nanocomposites show excellent electro-catalytic activity towards oxidation of DA and UA. The AuNPs(EDAS) – rGO nanocomposites exhibit low detection limits, high sensitivity, it could be a potential candidate for sensing application and in biosensor technology in the future.
A one-step electrochemical route for the synthesis, functionalization and deposition of Au nanostructures and for the bi-enzyme functionalization of a Au electrode has been proposed.
LbL films of AgCl–PANI nanocomposites synthesized by the one-step chemical route were shown to be a potential material for sensing application in which PANI de-doping at high pH is to be avoided.
