Abstract: Curcumin, a natural polyphenol exhibits chemopreventive and chemotherapeutic activities towards cancer. In order to improve the bioavailability and therapeutic efficacy, curcumin is encapsulated in alginate aldehyde-gelatin (Alg Ald-Gel) nanogels. Alginate aldehyde-gelatin nanogels are prepared by inverse miniemulsion technique. Physicochemical properties of the curcumin loaded nanogels are evaluated by, Dynamic light scattering (DLS), NMR spectroscopy and Scanning electron microscopy (SEM). Curcumin loaded nanogels show hydrodynamic diameter of 431 +/- 8 nm and a zeta potential of 36 +/- 4 my. The prepared nanogels exhibit an encapsulation efficiency of 72 +/- 2%. In vitro drug release studies show a controlled release of curcumin from nanogels over a period of 48 h. Hemocompatibility and cytocompatibility of the nanogels are evaluated. Bare nanogels are cytocompatible and curcumin loaded nanogels induce anticancer activity towards MCF-7 cells. In vitro cellular uptake of the curcumin loaded nanogels using confocal laser scanning microscopy (CLSM) confirms the uptake of nanogels in MCF-7 cells. Hence, the developed nanogel system can be a suitable candidate for curcumin delivery to cancer cells. (C) 2016 Elsevier B.V. All rights reserved.
