CdSe nanoparticles with polystyrene (PS) brushes are obtained by "grafting through" technique starting from solely aqueously synthesized nanoparticles. Mercaptoethanol (ME) capped nanoparticles are used to achieve double bond functional groups on the surface by condensation reaction with methacryloxypropyltrimethoxysilane (MPS). PS

Four [(CdSe)13(RNH2)13] derivatives (R = n-propyl, n-pentyl, n-octyl, and oleyl) are prepared by reaction of Cd(OAc)2·2H2O and selenourea in the corresponding primary-amine solvent. Nanoclusters grow in spontaneously formed amine-bilayer templates and are characterized by elemental analysis, IR spectroscopy, UV-vis spectroscopy

Microbial cells have shown a great potential to biosynthesize inorganic nanoparticles within their orderly regulated intracellular environment. However, very little is known about the mechanism of nanoparticle biosynthesis. Therefore, it is difficult to control intracellular synthesis through the manipulation of
