London, ENG– Fabric with color-changing aspects have been tinkered with in the fashion industry for some time now. But researchers from the University of Bath in London are looking to take this idea and apply it to healthcare and ultimately solve major issues in the detection of deadly infections.
The researchers have just released a prototype of a color-changing bandage that glows bright green to signify signs of a potential wound infection. The product (still in prototype stage) is poised to decrease the amount of overprescribing of antibiotics that occurs every year and proactively spot early signs of infection well before a patient gets sick.
These bandages are lined with an outer layer of a dye-containing capsule that pop when they come in contact with certain toxins within the bacteria. Once enough toxins are detected, microbes prompt the release of the dye that turns bright green when it mixes with the bandage lining.
