Biocompatible carbon-doped MoSe2 nanoparticles as a highly efficient targeted agent for human renal cell carcinoma.

ABSTRACT

MoSe2 is a typical transition-metal dichalcogenide material, and many researches have been focused on using its property of near infrared strong absorption for laser mediated photothermal cancer treatment. However, the anti-canter effect of MoSe2 and its possible mechanism in renal cell carcinoma (RCC) is still unclear. RCC has high incidence of metastasis, which is known as one of the most lethal malignancies in the urological system. This study revealed that the carbon-doped MoSe2 particles can obviously inhibit proliferation for 786-O and ACHN cells. Meanwhile, the carbon-doped MoSe2 nanoparticles have little impact on the viability of KH-2 cells in vitro. The mechanism analysis revealed that the carbon-doped MoSe2 particles have hydrogen bond effect in aqueous solution, and the particle aggregation effect caused the KH-2 cells to have high viability. The carbon-doped MoSe2 nanoparticles with minimal toxicity may be a potential therapeutic candidate against RCC.
