One‐Step Photochemical Green Synthesis of Water‐Dispersible Ag, Au, and Au@Ag Core–Shell Nanoparticles

One‐Step Photochemical Green Synthesis of Water‐Dispersible Ag, Au, and Au@Ag Core–Shell Nanoparticles

A simple and green synthetic protocol for the rapid and effective preparation of Ag, Au and Au@Ag core–shell nanoparticles (NPs) is reported based on the light irradiation of a biocompatible, water‐soluble dextran functionalized with benzophenone (BP) in the presence of AgNO3, HAuCl4, or both. Photo...

Zusammenfassung:A simple and green synthetic protocol for the rapid and effective preparation of Ag, Au and Au@Ag core–shell nanoparticles (NPs) is reported based on the light irradiation of a biocompatible, water‐soluble dextran functionalized with benzophenone (BP) in the presence of AgNO3, HAuCl4, or both. Photoactivation of the BP moiety produces the highly reducing ketyl radicals through fast (
