Abstract
In the current paper we present preliminary data demonstrating therapeutic efficiency of local laser hyperthermia of mouse tumors with gold nanoparticles. Measuring the tumor temperatures both superficial and inner by means of standard NIR-thermograph and original acoustic thermometer correspondingly we show that the gold nanoparticles increase thermal sensitivity of tumor tissue. Transmission electron microscopy and histopathology of the tumor tissue indicated that the mechanism of apoptotic death of tumor cells is triggered following the laser treatment. 5 days after the treatment tumor growth inhibition was 104 %.
