Incorporation of Hydroxyapatite/Doxorubicin into the Chitosan/Polyvinyl Alcohol/Polyurethane Nanofibers for Controlled Release of Doxurubicin and Its Anticancer Property

Abstract

In the present study, the doxorubicin-hydroxyapatite (DOX-HAp) has been loaded into the chitosan/PVA/PU single layer and core-shell nanofibers. The potential of synthesized nanofibers was evaluated for controlled release of DOX and bone cancer treatment in vitro. The synthesized DOX-HAp nanohybrid was characterized using XRD, SEM, and UV-Vis analysis. The morphology of synthesized nanofibers was examined by SEM and TEM analysis. For single layer nanofibers, some DOX-HAp nanohybrids were observed on the nanofibers surface. The fiber diameter was increased by increasing shell flow rate and no DOX-HAp nanohybrids were detected on the core-shell fibers surface. The DOX encapsulation efficiency of single layer and core-shell layer fibers was higher than 90 %. The initial burst release from single layer fiber at initial hours and the continuous release of DOX was observed from single layer nanofibers during 7 and 10 days under acidic and physiological pH. The sustained release of DOX was obtained within 10 and 14 days, 15 and 18 days, 21 and 25 days from core-shell fibers with flow rates of 0.3, 0.5 and 0.8 ml/h under acidic and physiological pH. The non-Fickian diffusion and Fickian diffusion were achieved from single layer and core-shell nanofibers. The cell attachment and cell death results indicated the high potential of DOX loaded-core-shell fibers for bone cancer treatment.
