abstract = {Bovine serum albumin (BSA)-protected AgPt bimetallic
nanoparticles have been synthesized through a galvanic
replacement reaction, using a silver nanoprism as a
template. Synthesis was performed without the use of
synthetic chemical surfactants, using proteins as a surface
coating. Structural and compositional characterizations were
performed using several spectroscopic and microscopic
techniques. The protein-protected AgPt nanoparticles show
effective pH-switchable enzyme mimicking (“nanozyme”)
activity similar to catalase and peroxidase. The platinum
content in the AgPt nanoparticles is playing an important
role in determining the enzymatic catalysis rate of the
nanoparticles. Because of their porous structure, molecular
payloads such as calcein also can be incorporated into the
AgPt nanoparticles, which can be released on demand by
chemical triggers, such as hydrogen peroxide.},
