New Hydrogel Can Repair, Regenerate Tissue
Posted on: Thursday, 19 July 2007, 08:36 CDT
U.S. scientists have developed a biomaterial that has antibacterial properties and can be used as a hydrogel to repair and regenerate human tissue.
University of Delaware researchers said the biomaterial can be injected as a low-viscosity gel into a wound where it rigidifies nearly on contact, opening the door to the possibility of delivering cells and antibiotics to repair damaged tissue.
The researchers said the new technology has the potential of regenerating healthy tissue in a cancer-ridden liver, healing a biopsy site and providing wounded soldiers in battle with pain-killing, infection-fighting medical treatment.
Associate Professors Joel Schneider and Darrin Pochan said their patented invention marks a major step forward in the development of hydrogels for medical applications.
Schneider and Pochan reported their research in the May 8 edition of the Proceedings of the National Academy of Sciences. Their research is funded by the National Science Foundation and the National Institutes of Health.
