Antibacterial Nanofibres for Wound Care

Abstract

The development of improved antibacterial strategies is an important global challenge.  This project aims to develop an effective new scaffold for topical antimicrobial and immunomodulatory therapy. This aim will be achieved by developing electrospun nanofibous polymer membranes that provide 1) flexible scaffolds, 2) inherent antimicrobial properties, and 3) controlled release of incorporated TLR-4 antagonists.  The fibres and membranes will be characterized using imaging methods. The antibacterial and immune modulatory effects will be tested in vitro and in vivo, using a murine model of diabetic +/-  ischaemic wound healing.
