TEOS as an improved alternative for chitosan beads cross-linking: A comparative adsorption study

In this work the use of tetraethoxysilane (TEOS) for cross-linking of chitosan hydrogel beads was studied at the level of 1 mmol TEOS per gram of chitosan. They were compared with glutaraldehyde and epichlorohydrin cross-linked beads. The hydrogels …
