Cobalt Phthalocyanine-Sensitized Graphene-ZnO Composite: An Efficient Near-Infrared-Active Photothermal Agent.

ABSTRACT: Herein, a promising near-infrared-responsive photothermal agent was designed by anchoring of rice grain-shaped ZnO particles over graphene (GR) nanosheets and subsequent sensitization with cobalt phthalocyanine (CoPc). Thus, produced GR-ZnO-CoPc was able to attain the temperature of 68 °C by irradiating to 980 nm laser for 7 min, which is extremely higher than the endurance temperature of cancer cells. The linear fashioned progression in the photothermal effect of GR nanosheets was conquered by immobilization of ZnO particles and successive sensitization with CoPc. The excellence found in the photothermal effect of GR-ZnO-CoPc was verified by estimation of its photothermal conversion efficiency. The photothermal conversion efficiency assessed for GR-ZnO-CoPc was higher than those for the p
