The dependence of the efficiency of photothermal conversion of laser-synthesized bismuth (Bi) nanoparticles (NP) on size characteristics for applications in photothermal therapy is studied. It was shown that a decrease in the mode and half-width of the size distribution causes an increase in the photothermal conversion efficiency. Despite a decrease in the extinction in the relative transparency window of biological tissues (650–950 nm), Bi NPs of smaller sizes exhibit a more pronounced photothermal response caused by an increased contribution of absorption to the extinction. The unique combination of physicochemical properties of laser-synthesized Bi NPs forms a new promising alternative to conventional sensitizers of photothermal therapy of oncological diseases.
