Abstract

Herein, a novel hemin functionalized hybrid aerogel (He@GMA) is synthesized and applied to an electrochemical chip for real-time analysis of hydrogen peroxide (H₂O₂). The He@GMA shows a typical three-dimensional morphology and excellent peroxidase-like catalytic performance. The He@GMA-enabled electrochemical chip presents satisfactory performance for H₂O₂ sensing with a low limit of detection (0.96 μM). Besides, the chip platform shows some advantages of less sample consumption and easier detection operation.
