Abstract
One aspect of the present disclosure relates to the use of vitrified active agents such as growth factors and/or one or more antimicrobial peptides (AMPs), or other desired active agent, for wound healing as a component of a wound dressing whereby the active agents are vitrified onto one or more polymeric materials, and their release rate regulated by the presence of one or more biodegradable polymeric materials.
Claims27
A wound dressing device comprising:
- a time release active agent delivery layer, the time release active agent delivery layer comprising a water stable polymer and a biodegradable polymer, the water stable polymer comprising one or more active agents in the form of a stable glassy vitrified material in contact with the water stable polymer, the time release active agent delivery layer configured such that the biodegradable polymer may release one or more active agents to a wound site over the course of a treatment time, wherein the one or more active agents comprise an antimicrobial peptide, an antibody, a growth factor, insulin, or combinations thereof.
