Abstract:

Polymer self-assembly has received special attention in the development of nanotechnologies especially for metallic nanoparticles synthesis. In this context, tailoring both nanoparticle shape and size has been intensified recently. Here, we use the vapor-induced phase separation (VIPS) method, which is homopolymer self-assembly to elaborate monodisperse metallic nanomaterials particularly relevant in sensing. To make it possible, a simple deposition of PMMA dispersion, doped with gold precursor onto silicon substrate allows a spontaneous formation of gold nanocubes (GNCs) loaded polymer holes (see Figure 1). To be able to control the structural and optical properties of these nanoparticles, crucial for SERS application, a physico-chemical study of the VIPS process was made. In particular, we investigated the influence of the precursor concentration to obtain monodisperse and uniform nanocubes. References 1. 1. Omar, R., Naciri, A.
