Abstract

Nitric oxide (NO) acts in several physiological processes such as wound healing and vasodilation, which has stimulated the development of hydrogels capable of releasing NO locally in biomedical applications. The main objective of this project is the development of photocrosslinkable NO donor hybrid hydrogels for the 3D printing of biomaterials. The hydrogels will be synthesized from the photopolymerization of acrylic acid in the presence of poly (ethylene oxide)-poly (propylene oxide)-poly (ethylene oxide) (PEO-PPO-PEO-F127) triblock copolymer and poly (vinyl alcohol) (PVA). The physical-chemical characteristics of the obtained hydrogels will be studied through swelling tests, mechanical tensile and compression tests and morphological characterization by scanning electron microscopy. Parts of these hydrogels designed for specific applications such as cartilage replacement will be made by photopolymerization in a 3D printer. The materials will be charged with S-nitrosoglutathione (GSNO) as the NO donor and the kinetics of real-time NO release under physiological conditions will be characterized by chemiluminescence.
