Facile preparation of Cu–Cu2O nanoporous nanoparticles as a potential catalyst for non-enzymatic glucose sensing

Abstract

We achieved the successful synthesis of Cu–Cu₂O nanoporous nanoparticles by the reduction of chalcanthite with ethylene glycol via a facile solvothermal method involving introducing oxygen. The resultant material showed a good linear dependence, an extraordinary limit of detection and a high sensitivity to the detection of glucose.
