The greenness of nanoenzymes is reflected in

Nano-enzymes catalyze the oxidation of TMB to develop color. Nano-enzymes catalyze h2o2 to make TMB color development, without adding hydrogen peroxide can make TMB color development green. Nano-enzymes are a class of simulated enzymes that have both the unique properties of nanomaterials and catalytic functions. Nanoenzymes are characterized by high catalytic efficiency, stability, economy and scale-up preparation, and they are widely used in the fields of medicine, chemical industry, food, agriculture and environment.
