One-pot facile synthesis of PEGylated Au nanoparticles in an aqueous media

► Facile, one-pot, aqueous synthesis of monodisperse PEGylated gold nanoparticles. ► Oligo(ethylene glycol)ethylethermethacrylate(PEGEEM) as reductant and stabilizer. ► Exclusion of extra reducing agents or multi-step synthesis of PEG stabilizers. ► Fabrication of Pd and Ag nanoparticles using PEGEEM in aqueous media. ► An excellent blockage of the BSA adsorption by PEGylated gold nanoparticles.
