Recently, molybdenum disulfide (MoS2), as one of the most stable layered transitional metal dichalcogenides, has attracted lots of attention because it shows high absorbance in the near-infrared (NIR) region, high surface area, good photothermal properties, and good biosafety. So it has been extensively applied as a novel photothermal agent in biomedical applications. Here, we examine two nanocomposites comprised of molybdenum disulfide-gold nanorod (MoS2–Au) and molybdenum disulfide-iron oxide magnetic nanoparticle (MoS2-Fe3O4) having unique structural features. These nanocomposites were developed by using facile preparation strategies; then, all samples (MoS2 nanoflakes, MoS2–Au, and MoS2–Fe3O4) were characterized by X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), Raman, Fourier transform infrared (FTIR), and ultraviolet–visible (UV–Vis) spectroscopies. These characterizations confirm that gold nanorods (AuNRs) and Fe3O4 nanoparticles have been incorporated between MoS2 nanoflakes separately. Finally, photothermal results of samples indicate that MoS2–Au nanocomposite produced higher photothermal heat than two other samples after 10-min laser irradiation. So, MoS2–Au nanocomposite can be a suitable photothermal agent for further biological applications such as photothermal therapy and drug delivery.
