This report describes a novel, one-pot synthesis of hybrid nanoparticles formed by a nanostructured inorganic silica core and an organic pH-responsive hydrogel shell. This easy-to-perform, oil-in-water emulsion process synthesizes fluorescently-doped silica nanoparticles wrapped within a tunable coating of cationic poly(2-diethylaminoethyl methacrylate) hydrogel in one step. Transmission electron...
Using apoferritin (apoFt) as a nucleation substrate, we have successfully synthesized 1–2 nm platinum nanoparticles (Pt–Ft) which are highly stable. By directly measuring the products of Pt–Ft-catalyzed reactions, we showed, with no doubt, Pt–Ft possesses both catalase and peroxidase activities. With hydrogen peroxide as substrate, we observed oxygen gas bubbles were generated from hydrogen peroxide...
