Design of an Intelligent Profiling Platform for Multiple Antibiotic Discrimination Enabled by Time-Resolved Histidine-Functionalized Cupric Oxide Nanozyme Sensor Array at Neutral pH.
Nanozymes with peroxidase-like (POD) activity have broad applications in biosensing, but their catalytic activity is often optimal under acidic conditions, which severely limits their applications in neutral environments. Here, we constructed a histidine-functionalized cupric oxide (CuO@His) nanozyme via defect enginee...
