Dual enzyme mimicry exhibited by ITO nanocubes and their application in spectrophotometric and electrochemical sensing

The dual enzyme mimicry (peroxidase/catalase-like activities) exhibited by ITO nanocubes (ITO NCs) was investigated by spectrophotometric and electrochemical methods. The peroxidase mimic was successfully applied for the electrochemical detection of H2O2 and spectrophotometric biosensing of glucose. Further, the detection could be extended to the detection of glucose in real samples.
