Scientists at Queen's University Belfast have developed a gel that acts to kill hospital superbugs.
It targets Pseudomonas aeruginosa, staphylococci and E.coli.
Lead researcher Dr Garry Laverty said: "Our gels are unique as they target and kill the most resistant forms of hospital superbugs.
"It involves the use of gels composed of the building blocks of natural proteins, called peptides - the same ingredients that form human tissue."
He added: "These molecules are modified slightly in the laboratory to allow them to form gels that will rapidly kill bacteria."
The School of Pharmacy at Queen's and the School of Chemistry at Brandeis University, Waltham, US, collaborated on the research.
Their results will be published in the journal, Biomacromolecules, next month.
