Development of a Self-Adhesive Cellulosic Hydrogel Wound Dressing

What is it about?

A cost-effective dressing for moderately-exuding wounds was developed from hydroxyethylcellulose hydrogels layered with an adhesive derived from tannic acid and polyethylene glycol. The resulting biomaterial combined the properties of both the hydrogel and the adhesive in providing a physiologically-conducive environment for wound healing. Variation of dressing parameters (e.g. adhesive thickness, patterns, etc.) was coupled with performance evaluation tests (e.g. antimicrobial and cytotoxicity assays, adhesive strength testing, surface characterization, etc.) for product optimization.
