Hierarchically Porous Chitosan–PEG–Silica Biohybrid: Synthesis and Rapid Cell Adsorption



original image

A hierarchically porous chitosan–PEG–silica (CPS) biohybrid has been prepared in a facile synthesis through in situ silica polycondensation within a chitosan–PEG hydrogel. This organic–inorganic composite is almost non-toxic and has quick cell-adsorptivity. As a result of its unique hierarchical structure and excellent biocompatibility, this CPS biohybrid has the potential to be used as a new biomaterial.
