There’s a huge demand for engineering materials that detect dangerous substances invisible to the naked eye, such as these gloves that change color in the presence of hazardous substances. Similarly, researchers at the University of Bath have been developing a material to detect potentially deadly bacteria on open wounds. Using a hydrogel containing fluorescent dye, the prototype wound-dressing glows in the presence of bacterial ‘biofilms’ — a state bacteria exist in that’s difficult for drugs to penetrate. Treating open wounds can be complicated by the presence of certain bacteria, which can lead to infections, prolonging treatment and making the situation…
