Abstract
In this study, we synthesized and characterized a novel starch glutaraldehyde cross-linked hydrogel for drug release. The hydrogel exhibited excellent properties such as absorption capacity and drug release. By optimizing the cross-linking reaction using varying concentrations of glutaraldehyde and reaction time, we obtained a hydrogel with a three-dimensional network structure, superior swelling properties, and mechanical strength. The results revealed doxycycline sustained and controlled drug release over a prolonged period, which could be adjusted by altering the cross-linking density of the hydrogel. Overall, the starch glutaraldehyde cross-linked hydrogel shows great promise as a drug delivery system with controlled release properties, applicable in pharmaceuticals and tissue engineering.
