    Journal: Langmuir; 2014 Feb 18; 30(6):1650-8. PubMed ID: 24495155.
    Abstract:
    Quantum dot based thermometry, in combination with double beam confocal microscopy, was used to investigate the absorption/heating efficiency of gold nanoparticles with different morphologies (nanorods, nanocages, nanoshells, and nanostars), all of them with an intense localized surface plasmon resonance within the first biological window, at around 808 nm. The heating efficiency was found to be strongly dependent on the geometry of the nanostructure, with the largest values found for gold nanorods and long-edge gold nanostars, both of them with heating efficiencies close to 100%. Gold nanorods and nanocages were found to have the largest absorption cross section per unit mass among all the studied geometries, emerging as optimum photothermal agents with minimum metal loading for biosystems.
