MPEG-CHO (MW 2000)

MPEG-CHO (MW 2000) is involved 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 chitosan chains to form a glutaraldehyde-type adduct, thereby functionalizing mPEG. This process of functionalization and crosslinking can affect the rigidity of the delivery system, enabling the crosslinked conjugate system to possess a slow-release function.
