mPEG-CHO (MW 20000) plays a role in creating three-dimensional porous scaffolds and acts as a delivery vector by carrying active substances. The -CHO functional group interacts with the -NH2 functional group of chitosan chains, forming a glutaraldehyde-type adduct, thereby functionalizing mPEG. This functionalization and crosslinking can affect the rigidity of the delivery system, enabling the crosslinked conjugate system to possess a slow-release function.
