Experimental and Theoretical Studies of Heat Transfer in Graphene/Agar under Laser Irradiation - Crimson Publishers
Experimental and Theoretical Studies of Heat Transfer in Graphene/Agar under Laser Irradiation by Siheng Su * in Crimson Publishers: Peer Reviewed Material Science Journals As an effective energy absorber, graphene is able to convert other energy sources to heat, which can be used for hyperthermia therapy, triggered drug release and clinical surgery. In this paper, photo to thermal conversion of graphene derivatives under continuous near infrared laser irradiation was investigated. Near infrared light is widely used in biomedical field because of its low light absorption and light scattering of biological tissue, resulting in deep penetration. Herein, to simulate the heating process inside biological tissue with graphene under near infrared light irradiation, graphene oxide was embedded in hydrogel and its temperature evolution under irradiation was experimentally and theoretically studied. Experimental results show that graphene oxide greatly enhances light absorption and ...
