Professor Hui Wei and coworkers have introduced a predictive descriptor—t 2 occupancy—to guide the design of spinel oxide-based nanozymes with enhanced peroxidase-like (POD) activity.

Schematic illustration of NB-rGO Reactions in Bioassays. Researchers were able to synthesize a peroxidase-mimicking nanozyme with superior catalytic activity and selectivity toward hydrogen peroxide.
