Multifunctional Hybrid MoS₂-PEGylated/Au Nanostructures with Potential Theranostic Applications in Biomedicine.

ABSTRACT: In this work, flower-like molybdenum disulfide (MoS₂) microspheres were produced with polyethylene glycol (PEG) to form MoS₂-PEG. Likewise, gold nanoparticles (AuNPs) were added to form MoS₂-PEG/Au to investigate its potential application as a theranostic nanomaterial. These nanomaterials were fully characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), photoelectron X-ray spectroscopy (XPS), Fourier-transformed infrared spectroscopy (FTIR), cyclic voltammetry and impedance spectroscopy. The produced hierarchical MoS₂-PEG/Au microstructures showed an average diameter of 400 nm containing distributed gold nanoparticles, with great cellular viability on tumoral and non-tumoral cells.
