A triblock copolymer was synthesized by ring opening polymerization of ε-caprolactone in the presence of poly(ethylene glycol) (PEG). The resulted PCL-PEG-PCL triblock copolymer, PEG and monomethoxy (MPEG) were functionalized by end group acrylation. NMR and FT-IR analyses evidenced the successful synthesis and functionalization of polymers.

Hybrid hydrogel was prepared by crosslinking glucose oxidase (GOx), vanadium metal-organic polyhedrons (VMOP-2) and chitosan using glutaraldehyde as crosslinker. The formed GVCS hydrogel was characterized by using various techniques, including FTIR, SEM, XPS, TGA and EDX.

The is mainly composed of epithelial and stromal cells, and they produce the first immune response to invading pathogens. However, most of the epithelial cells are disrupted, and stromal cells are exposed to an inflammatory environment when endometritis occurs, especially postpartum.
