Abstract:
The objective of the present study is to evaluate the potential of novel molybdenum disulfide (MoS2)-based nanocomposites for photothermal therapy. For this purpose, MoS2-CuS (MoCS) and MoS2-AuNR (MoAu) nanocomposites were synthesized by physically mixing MoS2 suspensions with CuS and AuNRs, respectively. The structural and optical properties of these nanocomposites were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), ultraviolet-visible (UV-Vis) spectroscopy, and Fourier transform infrared (FTIR) spectroscopy. The photothermal performance of the nanocomposites was assessed under near-infrared (NIR) radiation at a power density of 1 W/cm2 for 10 min. The results demonstrated that both MoCS and MoAu nanocomposites exhibited enhanced photothermal heating compared to their individual components. Furthermore, the MoAu nanocomposite generated higher photothermal heat than the MoCS nanocomposite. These findings suggest that the MoCS and MoAu nanocomposites have strong potential as novel photothermal agents for cancer therapy.

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
