The interaction of semiconductor quantum dots CdZnSe/ZnS (QDs) and gold nanoparticles (Au NPs) in colloidal solutions was investigated. The replacement of ligands on the Au NP surface by mercaptocarboxylic acid molecules is shown to produce stable complexes of bound Au NPs and hydrophobic QDs with surface purified of organic ligands.
