Background of the study: Skin injuries are just one of the many existing challenges in the healthcare domain. Such a diverse range, from burns to chronic wounds, is diverting attention towards biomaterial-based approaches for wound healing, including hydrogels as a possible alternative to traditional methods using tissue-engineered skin grafts. However, serious skin injury rehabilitation, like diabetic foot ulcers, requires further research and compelling advanced solutions that underline the importance of wound healing and recovery.
Methodology: Hydrogel blends were prepared using Polyvinyl Alcohol (PVA) and Polyethylene Glycol (PEG) solutions, and combining them in a specific 75:25 ratio. Glutaraldehyde (GA) was added in varying amounts of 3%, 5%, and 8% to promote chemical cross-linking of the two polymers to achieve enhanced mechanical stability of the hydrogel films. Preliminary characterization tests were then conducted on all the samples to assess the physical properties of the synthesized hydrogel films.
Results: The PVA-PEG hydrogel films showed favorable results, with controlled degradation characteristics throughout the experimental period. The prolonged swelling and degradation properties of PVA-PEG hydrogel films may suggest suitable applications in wound healing scenarios. Therefore, this reflects the versatility of PVA-PEG hydrogels in dealing with innumerable skin injuries and their potential application for rehabilitation studies.
Conclusion: PVA-PEG hydrogel synthesis with the integration of GA provides an interesting approach being developed for skin rehabilitation, as it provides mechanical stabilization and controlled degradation. These hydrogels show great promise for innovative approaches towards wound healing, particularly in treating conditions such as diabetic foot ulcers. Future studies need to perform cytocompatibility and various biological tests to facilitate easy clinical translation and elucidate the potential of biomaterial-based methods in improving patient outcomes in wound care and rehabilitation.
