Peroxidase, usually derived from horseradish, is a common enzyme used in clinical testing reagents. It is widely used not only in several biochemical assays but also in immunoassay (ELISA) kits. As a ...

(Nanowerk Spotlight) Nanoparticles that mimic the complexity and function of natural enzymes can act as effective peroxidase to catalyse for the oxidization of 3,3’,5’5-tetramethylbenzidine (TMB), ...

Figure 1. Comparison of the catalytic activities of various nanozymes and horseradish peroxidase (HRP) toward TMB and H2O2. (Image: KAIST) Enzymes are the main catalysts in our body and are widely ...

Nanozymes are functional nanomaterials, such as metal oxides, with enzyme-like properties. Their ability to produce reactive oxygen species like hydroxyl (• OH) radicals makes them especially useful ...
