Metal nanoparticles show the ability to generate heat under optical illumination. The light to heat conversion is especially strong when the nanoparticles are excited by a light frequency corresponding to their plasmon resonance position. We are interested in this photothermal effect because the heat generated in metal nanoparticles, especially gold nanoparticles, can be used in various biomedical applications such as imaging, drug delivery and therapy. We are presenting the results of light to heat conversion experiments on self-synthesized sphere shaped metal nanoparticles as well as nanorods and hollow spheres. The dependence of temperature increase in those particle solutions from particle size, shape, concentration and ligand shell type is investigated. The results will further be compared to theoretical studies by Govorov and Richardson.
