7. Some elements of thermo-plasmonics

7.1 A nanoparticle is a nanosource of heat.

LSPR is characterized in particular by a resonance absorption peak. This corresponds to maximum absorption of light energy, which is entirely converted into heat in most situations. As a result, plasmonic NPs act as nanometric heat sources that can be activated by light. This has given rise to a significant number of studies and a few applications, such as plasmon-assisted nanochemistry, photothermal imaging, nanosurgery, and photothermal cancer therapies. Today, there is talk of a new field of study, thermo-plasmonics
