[en] nanoparticles ; polymer
[en] We report on a simple procedure to tune the hydrophilicity of hybrid gold nanoparticles. The nanoparticles have
been prepared in the core of a poly(ethylene glycol)-block-poly( -caprolactone) (PEG-b-PCL) five-arm star block
copolymer. A hydrophilic corona was then added to these hybrid gold nanoparticles by direct chemisorption of
trithiocarbonate-containing poly(acrylic acid) chains. These polymers were synthesized by RAFT polymerization with
a trithiocarbonate as the chain-transfer agent. The efficiency of the grafting was evidenced by TEM, AFM, and DLS
and by the successful transfer of these nanoparticles from organic solvent to water.
