Abstract

Gold nanoparticles can be engineered to target cancerous cells and at the same time designed to absorb specific wavelengths of light. Consequently, with the presence of optically-tunable gold nanoparticles such as gold nanoshells, light can be effectively converted to heat via photothermal effect well enough to raise the temperature of medium surrounding gold nanoshells for thermal ablation or hyperthermia treatments of cancers. For further development and clinical translation of gold nanoparticle-aided thermal therapy, it is essential to have a computational tool by which the heat distribution within the tumor and surrounding tissues can be estimated. In this seminar, an overview of a computational model developed by Dr. Cho’s research group will be presented.


Biography

Dr. Sang Hyun Cho is currently an Associate Professor of Medical Physics at Georgia Tech. He received his Ph.D. in Nuclear Engineering specializing in Medical Physics from Texas A&M University, College Station. He came to Georgia Tech in January 2007 from The University of Texas M. D. Anderson Cancer Center, Houston, where he was an Associate Professor of Radiation Physics. He is a certified medical physicist in therapeutic radiologic physics by the American Board of Radiology and a licensed medical physicist in the same specialty by the State of Texas. His recent research has been focused on the use of gold nanoparticles for cancer therapy and detection.
