Anisotropic nanostructures for their self-assembly have been of great interest to develop unique optical properties as well as physicochemical characteristics. In this study, we report controlled self-assembly of anisotropic bimetal-polymer nanoparticles for a variety of biomedical applications. Bimetallic core-shell nanoparticles composed of Au and Ag were eccentrically encapsulated with the polymer, resulting in formation of the anisotropic bimetal-polymer nanoparticles. As characterized by UV-Vis absorption, dynamic light scattering, zeta-potential and transmission electron microscopy, the anisotropic bimetal-polymer nanoparticles were self-assembled into the clustered architectures via noncovalent interaction when their diametric functionalities at each compartment were selectively modified. Conclusively, this work has great potential for controlled particular assembly and photonics-based biosensing. |
