Heat generation with plasmonic nanoparticles

by H. Ammari and F. Romero and M. Ruiz

(Report number 2017-14)

Abstract
In this paper we use layer potentials and asymptotic analysis techniques to analyze the heat generation due to nanoparticles when illuminated at their plasmonic resonance. We consider arbitrary-shaped particles and both single and multiple particles. For close-to-touching nanoparticles, we show that the temperature field deviates significantly from the one generated by a single nanoparticle. The results of this paper open a door for solving the challenging problems of detecting plasmonic nanoparticles in biological media and monitoring temperature elevation in tissue generated by nanoparticle heating.

Keywords: plasmonic nanoparticle, plasmonic resonance, heat generation, Neumann-Poincare operator.
