Nanotechnology ‘can help prevent bone infections’

A new nanotechnology-based technique for combating the bacteria and other harmful microorganisms that cause deep bone infections has been developed by researchers.

The study from the University of Sheffield's School of Clinical Dentistry showed applying small quantities of antibiotic to the surface of medical devices – from small dental implants to hip replacements – could protect patients from serious infection.

Using nanotechnology to work on small polymer layers inside implants, measuring between one and 100 nanometers, this approach is expected to deliver significant benefits for patients at high risk of infection, such as trauma victims.

This is a potentially significant discovery given that deep bone infections associated with medical devices are increasing in number, especially among the elderly.

Paul Hatton, professor of biomaterials sciences at the University of Sheffield, said: "As well as improving the quality of life, this new application for nanotechnology could save health providers such as the NHS millions of pounds every year."

Preventing infections in healthcare settings is considered a key challenge in care provision, particularly given the growing prevalence of antibiotic-resistant superbugs.
