I-PT: An Index to Rank Molecular Photothermal Agents
Résumé
Recently, a large variety of photothermal agents have been developed and are currently under study, owing to their wide range of applications. Nonetheless, a comparison of their relative performances remains a challenge, and it appears that no tool is yet available for rationalizing the data reported in the literature. Indeed, we demonstrate in this paper that neither the temperature increase (Delta T) nor the photothermal efficiency (eta) are sufficient to account for the performance of a photothermal agent. From this observation, we propose that a new index, I-PTmax, could be used, in order to properly rank molecular photothermal agents according to their efficacy for converting light into heat, in a similar fashion that brilliance is used to compare luminescence properties.
