A sustainable, plant-based wound dressing that delivers antibiotics before infection spreads could offer a greener and more efficient alternative to conventional wound care. The two-sided dressing developed by researchers at the University of Bath releases the broad-spectrum antibiotic tetracycline directly into wounds while maintaining a protective healing environment. Many advanced wound dressings rely on petroleum-based plastics or require additional chemical treatments. This allowed researchers to create a smart, two-sided dressing without any additional chemical modification. The wound-facing side contains tetracycline, a commonly used antibiotic, which is rapidly released into the wound.
