Location control of Au/CdS nanoparticles in block copolymer micelles

Abstract

Micellar core-embedded Au or CdS nanoparticles (NPs), in which the number of NPs was controlled by a solid type or a solution type of metallic precursors and by their amounts, were constructed using a block copolymer as a template. The location of NPs located at the micellar core was dramatically changed to the corona by the solvent-induced micellar core-corona inversion. By mixing the synthetic methods demonstrated, harmonious Au/CdS NPs with different particle sizes, numbers, and positions in the micellar core were also prepared.
