Abstract Scope Over the past decades, gold and silver nanoparticles and their composites have received extensive attention owing to their unique properties called “localized surface plasmon resonance (LSPR)” that enables them to absorb and reradiate photons when they are exposed to electromagnetic radiation. This property made them promising candidates for chemical and biochemical sensing. The extreme levels of sensitivity arise from the LSPR associated with the nanogap of assembled nanoparticles. Using new models of interaction between nanoparticles, we have achieved a tighter localized plasmonic field, down to 2 nanometers apart in order to overcome the conventional detection limit. We also examined the plasmonic photothermal therapy by inducing localized plasmonic heating at the nuclear region of the cells. This study has provided valuable insight into the application of nanoparticles in medicine and molecular biology.
