The team used a technique known as neutron reflectometry at STFC's ISIS facility in Oxfordshire to examine how Polymyxin B, a last resort antibiotic, interacts with the outer membrane of Gram-negative bacteria. These hardy bacteria are responsible for life-threatening diseases like pneumonia and meningitis, making them key targets for clinical research.

The more scientists can learn about these bacterial membranes, and the interactions of drugs with them, the greater chance we have of targeting the threat of antibiotic resistance and the impact on our ability to treat disease.
