Medicinal plants are considered to be bioactives valuable sources of anti-cancer. But these compounds are hydrophobic in nature and thus show decreased bioavailability. To overcome this issue, biocompatible drug delivery agents could be conjugating with these bioactives to improve their therapeutic efficacy. In the present study Curcumin loaded dextran coated Fe3O4NPs was synthesized by chemical precipitation method and coated with Dextran (DEX) using diffusion method. The structural, morphological and the magnetic properties of the prepared materials were studied by using Fourier transform infrared (FT-IR) spectro- scopy, transmission electron microscopy (TEM), X-ray diffraction (XRD), dynamic light scattering (DLS), zeta potential and Vibrating Sample Magnetometer (VSM). The MTT (3-(4,5-dimethylthiahiazol-2-yl)-2,5-diphenyl tetrazolium) assay of CUR loaded dextran coated magnetite nanoparticles (CUR/DEX/Fe3O4)NPs exhibited notable toxicity against MCF7 cells in a dose and time dependant manner. The IC50 values were 177μg/ml and 109μg/ml after 24h and 48h incubation respectively.
