What is it—and why does it matter?

In this hydrogel design, oxidized hyaluronic acid is chemically conjugated to the copper(II) complex of the peptide GHK (GHK-Cu2+). The evidence base summarized consisted mostly of preclinical studies with two randomized controlled trials.

    To overcome this limitation, we have developed a multifunctional injectable hydrogel, HCG@CDs, by cross-linking biocompatible carboxymethyl chitosan (CMCS) with oxidized hyaluronic acid (OHA) conjugated to the Glycyl-L-Histidyl-L-Lysine-Copper(II) complex (GHK-Cu2+) via dynamic Schiff-base linkages.
