what is a proper protocol i can follow for an experiment regarding nano fabrication of hollow structures in SPR? , for example the methods and the instruments needed, chemical solutions, etc, and thanks.
Porous nanomaterials are synthesized by a sol-gel method (metal and non-metal oxides) or an electrochemical method. Porous silicon is obtained by electrochemical method in the presence of hydrofluoric acid. Surface plasmon resonance appears when electromagnetic radiation interacts with a collection of electrons (plasmons) on the surface of nanoparticles of gold, silver ... Therefore, it is necessary to synthesize a hollow structure, and then attach gold nanoparticles in the cavity. A detailed description must be found by yourself by keyword.
