AgCu@CuO Aerogels with Peroxidase-Like Activity and Photoelectric Response for Sensitive Biosensing

Photoelectrochemical (PEC) enzymatic biosensors integrate the excellent selectivity of enzymes and high sensitivity of PEC bioanalysis, while the shortcomings of high cost, poor stability, as well as tedious immobilization of natural enzymes on photoelectrodes, severely suppress their applications. AgCu@CuO aerogel-based photoelectrode material with both remarkable enzyme-like activities and outstanding photoelectric properties was innovatively designed and synthesized to evaluate the activity of xanthine oxidase with a wide linear detection range and a low limit of detection.
