Photoelectrochemical (PEC) enzymatic biosensors integrate the excellent selectivity of enzymes and high sensitivity of PEC bioanalysis, but the drawbacks such as high cost, poor stability, and tedious immobilization of natural enzymes on photoelectrodes severely suppress their applications. AgCu@CuO aerogel-based photoelectrode materials with both remarkable enzyme-like activities and outstanding photoelectric properties were innovatively designed and synthesized to evaluate the activity of xanthine oxidase with a wide linear detection range and a low limit of detection.
光电化学（PEC）酶生物传感器将酶的优异选择性和 PEC 生物分析的高灵敏度结合在一起，但天然酶在光电极上的高成本、较差的稳定性和繁琐的固定化等缺点严重抑制了它们的应用。创新性地设计和合成了具有显著类酶活性和优异光电性能的 AgCu@CuO 气凝胶基光电电极材料，以评估黄嘌呤氧化酶的活性，具有较宽的线性检测范围和较低的检测限。
