Abstract
Albumin immobilized nanoparticles are known to be biodegradable, easy to prepare and reproducible for drug delivery systems. In summary, we have synthesized a new drug carrier using modified iron oxide nanoparticles. The synthesized drug carrier was characterized by X-ray powder diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), Fourier transform infrared (FT-IR), vibrating sample magnetometry (VSM) and energy-dispersive X-ray spectroscopy (EDX). Three different drugs were loaded on the modified iron oxide nanoparticles and then human serum albumin (HSA) immobilized on the iron oxide nanoparticles. In addition, the in-vitro antiproliferative activity of Fe3O4@SiO2@Nev@HSA nanoparticles against Hela cancer cell line using MTT colourimetric assay was compared with nevirapine. The results show that Fe3O4@SiO2@Nev@HSA nanoparticles in comparison to nevirapine itself have more effective antiproliferative activity on Hela cancer cell lines. The IC50 value for Fe3O4@SiO2@Nev@HSA nanoparticles was 59.20 μg/ml, which is close to the antiproliferative activity of anti-cancer gefitinib with IC50 value of 76.24 μg/ml. Moreover, in vitro calf thymus DNA (ct-DNA) binding studies were investigated by various spectroscopy techniques.
