Metal Nanozyme with Ester Hydrolysis Activity in the Presence of Ammonia‐Borane and Its Use in a Sensitive Immunosensor

Metal nanoparticle surfaces are used for peroxidase‐ and oxidase‐like nanozymes but not for esterase‐like nanozymes. It is challenging to obtain rapid catalytic hydrolysis on a metal surface and even more so without a catalytically labile substrate. Here, we report that metal nanoparticle surfaces r...
