Functional Hydrogels for Treatment of Chronic Wounds

Gels, Journal Year: 2022, Volume and Issue: 8(2), P. 127 - 127

Published: Feb. 17, 2022

Chronic wounds severely affect 1-2% of the population in developed countries. It has been reported that nearly 6.5 million people United States suffer from at least one chronic wound their lifetime. The treatment is critical for maintaining physical and mental well-being patients improving quality life. There are a host methods wounds, including debridement, hyperbaric oxygen therapy, ultrasound, electromagnetic therapies, negative pressure skin grafts, hydrogel dressings. Among these, dressings represent promising viable choice because tunable functional properties, such as biodegradability, adhesivity, antimicrobial, anti-inflammatory, pre-angiogenic bioactivities, can accelerate healing wounds. This review summarizes types phases process, key therapeutic approaches. Hydrogel-based reviewed multifunctional properties advantages Examples commercially available also provided to demonstrate effectiveness over other healing.

Enhanced Strength for Double Network Hydrogel Adhesive Through Cohesion‐Adhesion Balance

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(23)

Published: Feb. 15, 2024

Abstract Hydrogel adhesives exhibit great potential in various biomedical fields such as tissue sealing and soft robotics. However, the high‐water content defective network structures of these hydrogel result low intrinsic mechanical strength, severely impeding their application. In this study, it is reported that strong adhesive strength can be achieved when a balance established between forces cohesive forces. Based on principle, new double (DN) design created to combine an polyvinyl alcohol (PVA) first with flexible sodium alginate (SA) second network. A delicate cohesion adhesion by adjusting ratio rigid As result, balanced DN exhibits approximately three times higher than non‐balance situation.
