Carbon nanoparticles suspension injection for photothermal therapy of xenografted human thyroid carcinoma in vivo.

ABSTRACT: Due to the unique structure, carbon nanomaterials could convert near-infrared (NIR) light into heat efficiently in tumor ablation using photothermal therapy (PTT). Carbon nanoparticles suspension injection (CNSI) is a commercial imaging reagent for lymph node mapping. CNSI has similar structural characteristics to other carbon nanomaterials, and thus, might be applied as photothermal agent. Herein, we evaluated the photothermal conversion ability and therapeutic effects of CNSI on thyroid carcinoma. CNSI was composed by carbon nanoparticle cores and polyvinylpyrrolidone K30 as the dispersion reagent. CNSI absorbed NIR light efficiently following the Lambert-Beer law. The temperature of CNSI dispersion increased quickly under the NIR irradiation. CNSI killed the TCP-1 thyroid carcinoma cell
