Abstract

Wound dressings aim to restore the milieu required for skin regeneration by protecting the wound from environmental threats, including penetration of bacteria, and by maintaining a moist healing environment. A wide variety of wound dressing products targeting various types of wounds and different aspects of the wound healing process are currently available on the market. Ideally, a dressing should be easy to apply and remove, and its design should meet both physical and mechanical requirements; namely water absorbance and transmission rate, handleability and strength. In this article, our novel biodegradable antibiotic-eluting wound dressings are described and the engineering aspects in the design are emphasized. These unique new wound dressings are based on a polyglyconate mesh, coated with a porous Poly(dl-lactic-co-glycolic acid) matrix. They demonstrated excellent mechanical and physical properties and desired release profiles of antibiotic drugs which enable bacterial inhibition. Hence, a new generation of wound dressings is now emerging with clear benefits. These include better protection against infection and reducing the need for frequent dressing changing.
