From the MIT Technology Review: A smart bandage signals infection by turning a fluorescent color. Researchers have developed a new kind of wound dressing that could serve as an early-detection system for infections. This could not only save lives, but reduce the need for antibiotics.
Bacterial infection is a fairly common and potentially dangerous complication of wound healing, but a new “intelligent” dressing that turns fluorescent green to signal the onset of an infection could provide physicians a valuable early-detection system.
Researchers in the United Kingdom recently unveiled a prototype of the color-changing bandage, which contains a gel-like material infused with tiny capsules that release nontoxic fluorescent dye in response to contact with populations of bacteria that commonly cause wound infections.
Led by Toby Jenkins, a professor of biophysical chemistry at the University of Bath, the inventors of the new bandage, which has not yet been tested in humans, say it could be used to alert health-care professionals to an infection early enough to prevent the patient from getting sick. In some cases it may even be able help avoid the need for antibiotics, says Jenkins.
Battlefield wounds are often dirty, infection, gangrene all too often led to amputation or death. I’m re-reading my way through the Patrick O’Brien Aubrey/ Maturin series of 18th Century sea stories, and there are plenty of shipboard wounds, and amputations, usually successful because Stephen Maturin was an excellent 18the century physician. But in the real world, it is a real problem. Our current military provides wonderful care, compared to their forebears. My family lost a young uncle on each side of the civil war to a battlefield wound and sepsis.
The article reminds us that caring for infected wounds costs billions of dollars annually. This is early on, but very promising.
