Preparation, Characterization, and Release Study of Nanosilica/Chitosan Composite Films

The development of film materials that can control the release drugs is needed to create a smart drug delivery system. This paper reports properties and kinetic studies models made chitosan nanosilica. Nanosilica was directly incorporated into solution modify enhance composites as potential carriers. Fourier transform infrared spectroscopy results acknowledge successful fabrication chitosan/nanosilica composite films. Wettability tests showed inclusion nanosilica could make more hydrophilic by incorporating up 5 wt%. effective diffusion coefficients obtained mathematical modeling were in range 10
