Bandages change color when they detect the presence of bacteria

Scientists have developed a bandage that changes color as it can detect and treat bacterial infections.


According to the World Health Organization, antibiotic resistance is one of the biggest threats to the world . The and treating bacterial infections as early as possible could help improve patient recovery, as well as the spread of antibiotic-resistant microbes.

Scientists at ACS Central Science they have manufactured a bandage that changes when it detects in wounds, drug-resistant bacteria and can be treated accordingly.

O Xiaogang Qu and his colleagues developed a που αλλάζει χρώμα από πράσινο σε κίτρινο όταν έρχεται σε επαφή με το όξινο μικροπεριβάλλον μιας βακτηριακής λοίμωξης. Σε απόκριση της ύπαρξης βακτηρίων, ένα υλικό που είναι ενσωματωμένο στον επίδεσμο, απελευθερώνει ένα αντιβιοτικό που σκοτώνει τα ευαίσθητα σε φάρμακα βακτηρίδια.

If drug-resistant bacteria are present, the dressing takes on a red color through the action of an enzyme produced by the resistant microbes. When this happens, the μπορούν να φωτίσουν το επίδεσμο, προκαλώντας το υλικό να απελευθερώσει αντιδραστικά είδη y that kill or weaken the bacteria, making them more sensitive to the antibiotic.

The team showed that the dressing could speed up wound healing in infected with drug-susceptible or drug-resistant bacteria. The Best Technology Site in Greecefgns
