Nanoparticle‐mediated photothermal therapy: A comparative study of heating for different particle types

Abstract

For the nanoparticles tested, the nanoshells generated more heat, per nanoparticle, than nanorods, primarily due to their overall larger geometric cross-section. Conversely, we found that the gold nanorods had a higher photothermal efficiency than the gold nanoshells. In conclusion, the ideal choice of plasmonic nanoparticle requires not only per particle efficiency, but also the in vivo particle targeting ability under study.
