To address the Army need for a dressing that combines the features of several commercial products designed to treat burns, Physical Optics Corporation (POC) proposes to develop a new Wound Curing Dressing (WCD) that will contain embedded growth factors, microbicidal agents, antiproteinases, and nutrients; be capable of absorbing wound exudates; be able to remain in place for up to 7 days; and have a shelf life of 2 years at temperatures ranging from -30 to 150 degrees F. This proposed dressing combines lyophilized platelets with nanocrystalline silver. The WCD will improve treatment, with better cosmetic and functional outcome for the patient and a speedier return to duty. In Phase I POC will demonstrate the feasibility of the WCD by fabricating the prototype and testing its biostimulating and microbiocidal effects in vitro. In Phase II POC plans to develop and demonstrate the efficacy of a prototype wound dressing and conduct in-depth testing in an appropriate animal wound healing model, comparing the prototype dressing with a standard moisture-retentive dressing.
