Preparation of Polymer Coated Gold Nanoparticles by Surface-Confined Living Radical Polymerization at Ambient Temperature
Abstract
Nanometer sized core−shell particles containing a gold core and poly(methyl methacrylate) (PMMA) shells were prepared by surface-confined living radical polymerization on gold nanoparticles. Gold nanoparticles were prepared in the presence of 11-mercaptoundecanol (MUD) and subsequently esterified with 2-bromoisobutyryl bromide (BIB). Atom transfer living radical polymerization was conducted on the Br-terminated gold nanoparticles using copper(I) bromide/1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane (Me 4 Cyclam) as a room-temperature catalyst. FTIR spectroscopy confirmed the presence of polymer on the nanoparticle surfaces. The resulting gold/polymer nanocomposite particles are stable in suspension. Transmission electron microscopy and UV−vis spectroscopy were performed to characterize the gold nanoparticles (GNPs).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
