Background: Alginate is one of the most widely used biopolymer for wound healing. But poor mechanical strength and degradability limits its application especially as a drug-delivery matrix. The aim of this study was to develop stable alginate based scaffold for insulin delivery toward wound care. Materials & methods: The xerogel alginate-g-poly (methacrylic acid; AGM2S) was characterized by various analytical techniques. Results: AGM2S xerogel showed improved physical stability, low degradation, good swelling and water vapour transmission rate (WVTR). About 70% of insulin was released from loaded xerogel over a period of 48 h and favorably modulated the healing response in in vitro scratch wound assay. Conclusion: Grafting improved the strength and stability of alginate xerogel and the results suggest the application of insulin loaded AGM2S xerogels as a potential wound healing material.
