Preparation and characterization of microporous bionanocomposites for biomedical applications

摘要: This article describes the preparation and characterisation of micro porous chitosan-silicon dioxidebionanocomposite via the incorporation of nano silicon dioxide nanoparticles into chitosan hydrogel. To explore the properties of prepared bionanocomposites were characterized by Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, UV-visible spectroscopy and high resolution transmission electron microscopy (HR-TEM). TEM observation revealed that the silica was dispersed in the chitosan matrix. The bionanocomposites showed enhanced porous properties. All these results suggested that the prepared bionanocomposite could be used for various biotechnological and environmental applications.
