Plant-Based Dressing That Releases Antibiotics Directly to Wounds

Breakthrough Development
Researchers at the University of Bath, in collaboration with the University of Bristol and Newcastle University, have created a two-sided wound dressing from a plastic-like material derived from plants. The dressing releases a therapeutic concentration of antibiotics into the wound within four hours while the opposite side acts as a barrier to maintain a protected healing environment. Laboratory tests showed a marked reduction in bacterial growth against two common wound-infecting bacteria and a more than 90 % decrease in biofilm formation, which typically impedes healing.
Context and Potential Impact
Wound infections cost the National Health Service (NHS) billions of pounds each year, delaying recovery and affecting patients’ daily lives. By targeting bacteria before they establish a biofilm, the new dressing aims to shorten healing times and reduce the financial burden on the NHS. Researchers stress that further pre-clinical and clinical testing is required before the product can be used in medical settings.
Official Statements & Responses
University of Bath scientists highlighted the difficulty the body has in combating early bacterial colonisation and the challenge of delivering drugs into established biofilms. They emphasized that preventing biofilm formation quickly could enable more effective wound healing. The study, published in *Bioactive Materials*, is the first to apply sustainable furan-based polymers—previously explored for eco-friendly plastics—to infection-fighting medical dressings.

- “Wound infections are very costly, and they can delay healing and affect people's lives day-to-day.” — Dr Hannah Leese, University of Bath
- “The body itself finds it really hard to fight back against the bacteria and it makes it much harder for the drugs that we use to get into that film to start to break it up and kill the bacteria as well,” — Prof Hannah Leese, University of Bath
- “We want to try to prevent that from forming as quickly as possible so we can ensure the wound can heal as effectively as possible.” — Prof Hannah Leese, University of Bath
- “Dr Xiang Ding, the study's lead author, added that the antibiotics released through the dressing will provide a barrier to protect the wound.” — Dr Xiang Ding, lead author
Next Steps
The research team plans additional laboratory investigations followed by pre-clinical trials to assess safety and efficacy before pursuing clinical studies.
