Plasmonic Particles of Gold-Polymer Micelles with Nanoporous Surfaces |
| 초록 |
Plasmonic particles of gold-polymer micelles were produced by evaporation-induced self-assembly. At first, polymer(PS-b-P4VP) micelles with Au precursors were assembled into spherical particles by evaporating toluene-in-water-emulsion. Then, Au precursors were transformed into Au nanoparticles by reduction process. Before reduction process, the addition of CTAB into the plasmonic particles resulted in the selective extraction of Au precursors within the micelles near the surface of the particle due to the strong electrostatic attraction between CTAB and Au precursors, followed by forming porous nanostructures on the plasmonic particles. The pore size could be varied by controlling the P4VP core diameter of the PS-b-P4VP micelles. The pore depth could be modulated independently by tuning the amounts of Au precursors that were incorporated into the micelles. This method was then generalized using other additives, producing both controlled inner and surface morphologies of the particles. |
