Abstract
The tremendous development of materials with fine tuning of their composition, shape, size and chemical functionalities at the nanometer scale has opened a wide range of applications, particularly in medicine. Metallic nanoparticles are extremely interesting for such developments. The fundamental study of surface plasmon resonance (SPR) versus the shape/size of a particle is an important challenge. In this field, we propose a synthetic strategy using an original biphasic emulsion process linked to chemo-reduction of gold salt HAuCl4. This method allows the preparation of new functional nanocapsules. These nanomaterials are fully characterized.
