Wounding yourself can be bad enough, but having to regularly remove the dressing to check for infection can be painful and can also compound things by exposing the wound and giving germs the chance to enter. Now researchers have developed a new material for dressings and plaster that changes color if an infection arises, making it possible to check wounds without changing the dressing.

Wow, will wonders never cease?  Next you’ll tell me that we have machines that can inject meds without needles!
