Polymer structures serve as 'nanoreactors' for nanocrystals with uniform sizes, shapes
Atlanta GA (SPX) Jun 14, 2013
Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures - including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals. The technique relies on the length of polymer molecules and the ratio of two solvents to control the size and uniformity of colloidal nanocrystals. The technique could facilitate the use of nanoparticles for o ... read more
