The aim is to get both the surface plasmon resonance (SPR) and catalytic performance of the composite material can be changed in response to external stimuli. Ag@poly(<i>N</i>-isopropylacrylamide-<i>co</i>-3-methacryloxypro-pyltrimethoxysilane) (Ag@P(NIPAM-<i>co</i>-MAPTMS)) hybrid microgels were synthesized by seed-emulsion polymerization using Ag nanoparticles (NPs) as the core and NIPAM/MAPTMS as monomers. Ag-Au@P(NIPAM-<i>co</i>-MAPTMS) bimetallic hybrid microgels were prepared by a galvanic replacement (GR) reaction between Ag NPs and HAuCl₄, with the composition and structure of these bimetallic nanocomposites being determined by the amount of added HAuClRSC advancesAg-Au bimetallic nanocomposites stabilized with organic-inorganic hybrid microgels: synthesis and their regulated optical and catalytic properties.PMC907963321173141Niu RZhang YLi LfalseAg-Au bimetallic nanocomposites stabilized with organic-inorganic hybrid microgels: synthesis and their regulated optical and catalytic properties.Herein, we present the synthesis of Ag-Au bimetallic nanocomposites stabilized with organic-inorganic hybrid microgels.
