How to prevent the spread of germs in hospitals

Inicio » EU News » How to prevent the spread of germs in hospitals

27/08/2019

Researchers have developed an antimicrobial adhesive material that could be used on hospital walls and floors to minimise contamination.

Infections that are caused by microorganisms like bacteria, viruses and some parasites, particularly drug-resistant ones known as superbugs, are a major threat to health worldwide. Their existence in hospitals leads to increasing mortality, patient suffering and rising healthcare costs.

The EU-funded FLEXPOL project has been developing a solution to this problem through a combination of materials and surface structures to provide a new means of sterilisation. The project team has produced a three-layered adhesive film with polypropylene (PP), a raw material used in food packaging applications.

These active substances, which are released in a controlled manner, are essential oils from natural resources like oregano or thyme with high antimicrobial efficiency. The top layer combines micro/nanostructures that mimic the lotus plant whose leaves have self-cleaning properties. The material developed by FLEXPOL partners prevents water from forming wet areas, thus obstructing the growth of bacteria.

“The combination of micropillars and nanospikes (black silicon) causes very high water contact-angles. This results in highly hydrophobic behaviour and creates a ‘lotus effect’ on the surface. As bacteria need a medium to grow, the absence of water effectively prevents the microorganisms from growing and spreading over the surface.”

The project team believes that the reduction in the transmission of infections in hospital settings will mean that fewer antibiotics will be used, ultimately helping to fight the dangerous increase of multidrug-resistant bacteria. The material will provide durable protection with good resistance on high-touch surfaces, and will ensure hygiene and patient safety, limiting the use of disinfectants.

Wide range of applications

The ongoing 3-year FLEXPOL (Antimicrobial FLEXible POLymers for its use in hospital environments) project will end in late 2019. In addition to healthcare, other application fields identified by project partners include public transportation, consumer goods and construction. For example, FLEXPOL material could be used to sterilise surfaces in buses or aircraft, or in public restrooms in transportation hubs and airports. Manufacturers of a variety of goods, from mobile phones and tablets to toys, as well as the packaging sector in food and drink production, could also benefit from FLEXPOL’s antibacterial film, according to the project website.
