Description
Summary:One of the critical issues in the cancer tussle is the innovation of drug delivery platforms for the extremely selective, controlled, and sustained release of anti-cancer drugs. We herein report the fabrication of chitosan (CS), magnetite (Fe 3 O 4 ), graphene Oxide (GO) nanoparticles, and their nanocomposites for high loading efficiency and subsequent release potentiality of Carboplatin (CARB) anticancer drug. Fourier transform infrared (FT-IR), X-ray diffraction (XRD), and high-resolution transmission electron microscopy (HR-TEM) were used to characterize the crystalline structure, functional structure, and morphology of the fabricated nanostructures. The average crystallite size of the as-prepared chitosan (CS), chitosan-coated magnetite (CS-Fe 3 O 4 ), chitosan-coated graphene oxide (CS-GO), and chitosan-coated magnetite graphene oxide (CS- Fe 3 O 4 -GO) nanocomposites was found to be 5.5, 70.5, 10.6, and 80 nm, respectively. The percentage loading of Carboplatin on CS, CS-Fe 3 O 4 , Cs-GO, and CS-Fe 3 O 4 -GO was 70, 81, 58, and 74%, respectively. The Carboplatin releasing results indicated promising cumulative release percentages at pH 5.0 and pH 7.4. The cumulative release percentages for CARB-CS, CARB-CS-GO, CARB-CS- Fe 3 O 4 , and CARB-CS-Fe 3 O 4 -GO at pH 5.0 were 87, 80, 88, and 90%, respectively. While the corresponding percentages at pH 7.4 were 84, 72%, 89, and 87%. The in-vitro cytotoxicity of carboplatin (CARB), CARB-CS-Fe 3 O 4 -GO, and CS- Fe 3 O 4 -GO was explored against two human cancer cell lines (MCF-7 and Hep-G2) using MTT assay. The CARB-CS- Fe 3 O 4 -GO exhibited the greatest surviving fraction at concentrations 5 and 12.5 µM against Hep-G2 and MCF-7 cell lines, respectively, compared to the free carboplatin (CARB). The results indicated that CS- Fe 3 O 4 -GO nanocomposite is a better candidate as a drug delivery nano-carrier for the Carboplatin anti-cancer drug.
