Smart strip that changes color in case of infection

Rhode Island: The purpose of Mary Patti is to keep the medicine on the wound and protect it from infection. Now with the help of a smart bandage, any kind of infection and germs can be detected on the wound.

Scientists at the University of Rhode Island have developed a smart strip that emits light in the event of an infection or infection. It can be molded into many shapes and sizes.

In case of fistula, diabetic wound and severe infection for any reason, the bandage has to be opened repeatedly. But the process can be very painful and frustrating. That’s why a thin membrane made of carbon nanotubes has been created. It can be combined with ordinary fibers of dressing polymer. In this way the nanotubes do not penetrate the wound but they do not stay away from the wound and continue to emit chemicals or liquids.
Hydrogen peroxide is a well-known chemical released in the event of wound healing or infection, which is released from white blood cells in the form of germs (bacteria, etc.). This chemical changes color when exposed to carbon nanotubes. For this, a small device is placed directly on top of the bandage and the bandage begins to glow from below. It can also be reported to a smartphone.

Muhammad Moin Saifi, an alumnus of the university, has done important work on this project. “Our invention detects wound infections at the outset,” he says. This way there is no need to use antibiotics indiscriminately and even amputation can be avoided. Thus, it can play an important role in the management of chronic canker sores and diabetic wounds.

It will first be tested on laboratory-made cells and then on mice.
