A nanocomposite of gold nanorods coated with Molybdenum disulfide (MoS2–GNRs) was fabricated in an aqueous solution and its photothermal heat was investigated upon exposure to near infrared (NIR) light irradiation. The optical property and morphology of all samples (MoS2, GNRs and MoS2–GNRs nanohybrids) were characterized by X-ray diffraction (XRD) and Ultraviolet-Visible (Uv-vis) spectroscopy. These characterizations confirm that GNRS are placed between MoS2 nanoflakes successfully. The photothermal results of samples indicate that temperatures of GNRS and MoS2 nanoflakes increase upon exposure to 808-nm continuous wave laser. But when MoS2 and GNRs are incorporated together, MoS2–GNRs nanohybrids produce higher photothermal heat than MoS2 individual sample. Photothermal experiment was also performed for different amounts of MoS2–GNRs aqueous solutions (1.2, 1.3, 1.4 and 1.5 mL). The result shows that the amount of concentration of GNRs affects the produced heat. The modified MoS2 nanoflakes with GNRs enhance photothermal heat thus these nanohybrids are well suited for further biological applications such as photothermal therapy and drug delivery.
