Electrospun Nanofibers as Dressings for Chronic Wound Care: Advances, Challenges, and Future Prospects

Chronic non-healing wounds show delayed and incomplete healing processes and in turn expose patients to a high risk of infection. Treatment currently focuses on dressings that prevent microbial infiltration and keep a balanced moisture and gas exchange environment. Antibacterial delivery from dressings has existed for some time, with responsive systems now aiming to trigger release only if infection occurs. Simultaneously, approaches that stimulate cell proliferation in the wound and encourage healing have been developed. Interestingly, few dressings appear capable of simultaneously impairing or treating infection and encouraging cell proliferation/wound healing. Electrospinning is a simple, cost-effective,…
