摘要
We obtained complexes between core/shell type CdSe/ZnS semiconductor nanoparticles (NP) and the synthetic polyelectrolyte polyallylamine (PAA) as a result of ionic interactions in aqueous solutions and subsequent stretching on flat substrates using the "molecular combing" technology. By varying the size of the nanoparticles and the stoichiometric ratios of the concentrations of nanoparticles and PAA molecules in solution, we determined the factors ensuring formation of filamentary fluorescent nanoparticle–PAA complexes.
