Heat transfer in suspensions of MoS2 demonstrate potential for near IR photothermal therapy

Our recent paper has demonstrated chemically exfoliated MoS2 as a near IR photothermal agent.  As described in our publication in Angewandte Chemie International Edition (Angewandte Chemie International Edition 52, 4160-4164 (2013)), we show that owing to an absorbance profile reaching into the NIR, ceMoS2 heats up rapidly upon NIR irradiation. Because of its high surface-area-to-mass ratio, ceMoS2 also possesses loading capacities on par with GO, the current best-in-class.  Clearly, ceMoS2 possesses many desirable traits present in the aforementioned photothermal agents.

The TDTT (time domain thermotransmission) measurements were conducted by Brian Foley during one of Visiting Professor Bryan Kaehr’s trips to our lab.  This work was in collaboration with Dr. Kaehr along with Professor Jeff Brinker at Sandia/UNM and Drs. Stanley Chou and Vinayak Dravid at Northwestern.
