Abstract

original image

Tiny reactors: By using a surfactant (see picture), domains of poly(ethylene glycol) (PEG) at the nanometer scale are dispersed within reverse micelles formed in supercritical CO2. The size and properties of the PEG domains are tuneable by changing the PEG content. Furthermore, the PEG domains have been used as nanoreactors to synthesize highly dispersed gold nanocrystals.
