In situ formation and immobilization of gold nanoparticles on polydimethylsiloxane (PDMS) exhibiting catalase-mimetic activity.

Published in: Chemical communications (Cambridge, England) (2020)

We report a heterogeneous reaction to reduce HAuCl4 solution and form gold nanoparticles (AuNPs) on stainless steel needle surfaces. Through bubbling of nitrogen, AuNPs dispersed into the solution homogeneously. Subsequently, AuNPs were immobilized on the surface of polydimethylsiloxane (PDMS). The immobilized AuNPs exhibit catalase-mimetic activity in a 2 wt% H2O2 solution.
