Summary:The problem of thermal interaction between the gold nanoparticle heated by pulse-periodic laser radiation and the biotissue in which the nanoparticle is placed is numerically solved. A linear dependence between the heating time of the medium and the ratio of the time between laser radiation pulses to the time of the pulse for particles equally spaced in the biotissue is obtained. From the results of numerical calculations of biotissue heating by the single particle heated by periodic laser radiation the distance between the particles necessary for effective thermal damage of the biotissue is estimated.
