Drug free antimicrobial surface technology.

Our technology can be adapted for use in a range of application from indwelling medical devices to coatings for domestic appliances.

Our Research

Our research is based around modifying existing polymer materials to confer them with antimicrobial properties, without any addition of chemical or metal ions. Using a small prototype, we have shown that our surfaces are able to kill ~35% of E. coli that attach to them. We aim to optimise our technology to kill a higher % of a range of different relevant pathogens.    

Reducing infection

Most persistent healthcare acquired infections (HCAIs) are due to indwelling medical devices becoming infected, which costs the NHS ~ £1 billion pounds a year in health complications and the negative health outcomes from these infections. Our drug-free approach to antimicrobial surfaces prevents the accumulation of bacteria that lead to infection, without the risks associated with introducing chemicals or metal ions into the body. This safer approach also helps to prevent the wider issue of antimicrobial resistant (AMR) pathogens, which is predicted to cause 10 million deaths by 2050 and seriously undermine many common medical treatments.  

Applications for BioSurf technology

Medical Device Manufacturing

Applying BioSurf technology to the surface of indwelling medical devices can help to reduce the health and economic impact of healthcare associated infections, without the use of chemical coatings which may leach into the body.

Domestic Appliance Manufacturing

Bacterial colonisation on domestic appliances (such as fridges and hand dryers) can drastically reduce their cleanliness and so performance. BioSurf coatings can prevent such fouling and give a better customer experience.

Food Packaging

Incorporating BioSurf technology into food package could help to increase the shelf-life of food products by helping to reduce the proliferation of bacteria which causes spoilage.      

Food Manufacturing

BioSurf technology can help to create more sterile environments for the safe preparation of food on a commercial scale.

Our Team

Our team’s main expertise lies in polymer physics, and the overlap between materials and biological physics. We also have strong expertise in microbiology and good links to the University of Sheffield Medical School.
