Fig. 10From: Synthesis and In Vitro Performance of Polypyrrole-Coated Iron–Platinum Nanoparticles for Photothermal Therapy and Photoacoustic Imaging a The optical image and the corresponding NIR thermographic images of the nude mouse before injection of FePt@PPy NPs. b The left side: the optical image of the nude mouse with subcutaneous injection. The dashed red circle indicates the location of the injection. The right side: the NIR thermographic image of the nude mouse after 6 min under irradiation at an 808-nm laser (1 W/cm2). Note that the maximum heating corresponds to the injection site. c Temperature change of the skin’s surface at the injection site and in the mice with irradiation at the 808-nm laser (1 W/cm2) for 6 minBack to article page
