Optimized nanocage for cancer photothermal therapy and comparison with other nanoparticles
Résumé
The purpose of this study is to get more efficient gold nanocages for photothermal therapy (PTT) of cancer. Therefore a numerical maximization of the absorption efficiency (generating heat) is achieved. Two therapeutic cases (using visible and infrared laser) are considered. The optimization leads to an improved absorption of the nanocages compared with previous studies. The optimized nanocages are also compared with other gold nanoparticles (nanorods, hollow nanospheres and nanoshells) and are shown to be more efficient when infrared light is used.
