Abstract

DESCRIPTION (provided by applicant): Collagen based biosynthetic materials have profoundly improved the outcome of reconstruction and restoration of congenital defects and traumatic injuries. This has been most apparent for massive burn victims that historically suffered lifelong severe scarring and lost of function following wound closure before the advent of these materials. Unfortunately the failure rate for biosynthetic implants is high, predominantly due to infection. This proposal intends to evaluate the feasibility of incorporating a silver technology directly into collagen biosynthetic scaffolding to impart short duration antimicrobial properties to prevent colonization during the first few critical days following surgical implantation. Currently, collagen implant failure rates exceeding 50 percent due to microbial growth lead to increased hospital stay, cause psychological distress to the patient, and retard healing and rehabilitation. In burns alone, over 51,000 Americans suffer could benefit from improvements in this material with additional benefits extending to plastic and reconstructive surgical applications that are increasingly using biosynthetic implants. It is the aim of this study to determine if antimicrobial activity can be incorporated into these important biomaterials for sustained release to control bioburden follow implantation. PROPOSED COMMERCIAL APPLICATIONS: If successful in reducing bioburden in biomaterials, this chemistry could be added to tissue graft and implant materials as a post treatment to reduce their likelihood of rejection due to infection. This will greatly enhance their effectiveness in healing difficult wounds and restoring to patients normal tissue function and quality of life.
