Swiss scientists develop wound dressing that kills bacteria

With antibiotic resistance becoming more widespread, researchers at the Swiss Federal Laboratories for Materials Science and Technology (Empa) have developed cellulose membranes equipped with antimicrobial peptides, which they believe could prove an effective solution against early bacterial infections such as Staphylococcus, particularly in complex wounds.

The research team led by Prof. Katharina Maniura from Empa’s Biointerfaces Laboratory in St Gallen, Switzerland, produced the membranes made of plant-based materials using electrospinning technology, with cellulose fibres with diameters of less than 1 µm spun to produce delicate, multilayered, three-dimensional fabrics.
