Researchers have developed a spray-on bandage for minor cuts and scrapes that helps to keep them clean and free from infection.
Based on a plastic that is used in Lycra, called polyethylene glycol, the thick liquid is sprayed on to the wound and sets within five minutes, the Daily Mail reported.
When the plastic sets it pulls the edges of the wound together, aiding healing and helping to prevent infection.
"Sprays allow more accurate and consistent delivery of the drug or treatment, and allow it to be held in the controlled sterile environment of a spray can," Sam Shuster from the Newcastle University said.
Spray-on teeth are also being developed by scientists at King's College London and Imperial College London.
The spray contains a type of calcium and helps repair damage to the tough outer coating of teeth
