One of the most clinically advanced forms of experimental disease-modifying treatment for Alzheimer disease is immunization against the amyloid β protein (Aβ)1,2,3,4,5,6,7, but how this may ...

Colorimetric reaction catalyzed by the peroxidase-like activity of natural enzymes (HRP) and mineral nanozymes with substrates (TMB). HRP, horseradish peroxidase. TMB, 3,3?,5,5?-tetramethylbenzidine.

The peroxidase-like activity of Pd-Ir nanoparticles was demonstrated by catalyzing the oxidation of TMB by H 2 O 2. Pd-Ir nanocubes (50 µl, 1.376 × 10 –13 M) were mixed with TMB substrate (50 µl, ...

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), generating an oxidised ...

The steady-state kinetics of XOD was recorded at 652 nm using a time-scan model of the microplate reader. Reactions without XOD-ASS or H 2 O 2 were set as controls. The peroxidase activity of XOD-ASS ...
