| Outline of Final Research Achievements |
Controlling the self-assemblies of functional nanoparticles is a key technology for development of optical, electronic and medical devices. In this research, we present the pH-responsive coassembly system of gold nanoparticles with external anionic polymers in aqueous solutions. Oligoethyleneglycol-coated gold nanoparticles were coassembled with poly(acrylic acid)s as an external mediator under the acidic condition. The assembly size was tuned by molecular weight of the anionic polymers and the induction of hydrophobic moiety into the polymers changed the responsive pH range.
