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, and reproducible process that can utilize both synthetic and natural polymers to address these specific wound challenges. Electrospun meshes provide high‐surface area, micro‐porosity, and the ability to load drugs or other biomolecules into the fibers. Electrospun materials have been used as scaffolds for tissue engineering for a number of years, but there is surprisingly little literature on the interactions of fibers with bacteria and co‐cultures of cells and bacteria. This Review examines the literature and data available on electrospun wound dressings and the research that is required to develop smart multifunctional wound dressings capable of treating infection and healing chronic wounds.
