 Context: A new ‘smart bandage’ helps in treating chronic wounds in a much more effective manner.

 

What is a smart bandage?

  • The bandage works by using biosensors to track the chemical composition of the wound exudates, which changes as the wound heals.
  • It also monitors pH and temperature to provide real-time information about infection and inflammation. The bandage has a hydrogel layer with electrodes that control the release of drugs. It is wireless, eliminating the need for bulky equipment and wired connections.
  • In tests, the bandage loaded with an antimicrobial substance proved effective against bacteria commonly associated with chronic wounds. It also enhanced tissue regeneration in skin cell investigations.
  • When applied to wounds in diabetic mice, the bandage accurately detected infection, inflammation, and metabolic statuses. Diabetic rats treated with the bandage and a combination of drugs and electrical stimulation showed faster wound healing and less scarring compared to those without this treatment.
