Abstract:

The cancer treatment by laser-conjugated nanomaterials has become a new developing trend due of their unique physicochemical performance. In this paper, two-phase colloidal method has been used to synthesize a novel Mn-doped CuS (Mn-CuS) nanoprism with high-surface area with different Mn concentrations (0%, 1%, 3% and 5%) for first time. The characterization of synthesized Mn-CuS involved the structural, compositional, surface charges, optical and morphological properties analysis. XRD showed that the Mn-doped covellite copper sulfide nanoparticles have hexagonal structure and additional diffraction peaks, which are assigned to orthorhombic chalcocite CuS were appeared. FTIR confirmed that the CuS and Mn-CuS have been prepared by two-phase colloidal synthesis method at 180 °C. The absolute values of zeta potential were indicated the suspension of CuS and Mn-doped CuS nanoprisms was electrostatically stabilized and the nanoparticles were stable and mono-dispersed. From UV–visible analysis, the absorption spectrum of Mn-doped CuS has two peaks: the first in UV–visible wavelength range and the second in NIR range. The optical band gap of Mn-CuS decreased as the Mn concentration increased. The TEM images showed that the 1% is best percentage of Mn to produce Mn-doped CuS nanoprism with uniform shape and size distribution and less average edge lengths. The best sample nanoprism (Mn-CuS 1% nanoprisms) was modified with gum Arabic for first time to decrease the cytotoxicity and increase the biocompatibility and investigated as photothermal agent in MDA-MB-231 cancer treatment. The results showed that the cancer cells were killed effectively by GA@Mn-CuS 1% nanoprisms. This indicated that GA@Mn-CuS nanoprisms are able to be used as an efficient theranostic agent for tumor photothermal therapy in the future.Affiliations: Journal instruction requires a city and country for affiliations; however, city is missing in affiliations 1 and 2.
