Singapore researchers today unveiled the first-ever antimicrobial hydrogel that can break apart biofilms and destroy multidrug-resistant superbugs upon contact.

Tests have demonstrated the effectiveness of this novel synthetic material in eliminating various types of bacteria and fungi that are leading causes of microbial infections, and preventing them from developing antibiotic resistance.

This discovery may be used in wound healing, medical device and contact lens coating, skin infection treatment and dental fillings.

The tests were carried out by researchers from the Institute of Bioengineering and Nanotechnology (IBN) and IBM Research.

More than 80 per cent of all human microbial infections are related to biofilm. Biofilms are microbial cells that can easily colonise on almost any tissue or surface.

They contribute significantly to hospital-acquired infections, which are among the top five leading causes of death in the US and account for US$11 billion in healthcare spending each year.

In Singapore, antimicrobial drug resistance is a major healthcare problem because of the extensive use of antibiotics and medical equipment such as intravascular catheters and orthopedic implants in patients.
