mPEG-CHO (MW 3400) participates in the formation of three-dimensional porous scaffolds and acts as a delivery carrier when combined with active substances. The -CHO functional group interacts with the -NH2 functional group of the chitosan chain to form a glutaraldehyde-type adduct, thus functionalizing mPEG. This functionalization and cross-linking can influence the rigidity of the delivery system, enabling the cross-linked conjugate system to have a slow release function.
