Hypochondriac Travelers Could Soon Prove They Have Infections

Bandages come in a variety of colors, from attempts to match flesh colors to neon and prints that show everyone that lost a fight with a piece of paper and ended up with a cut, and the wood pulp one. But, a new bandage promises to change colors when you get an infection.

It works a lot like the litmus paper test you slept through in chemistry class, or the pH tests lifeguards run in pools. According to DVICE, German researchers injected an indicator dye into a bandage that changes color based on the pH of the skin it covers. Five is normal for skin, anything too far above that is a sign of infection, turning the bandage purple.

We don’t recommend using litmus paper or pool tests for a replacement while bandage makers decide whether or not to use the Fraunhofer Institute’s new discovery in their product lines. However, in the meantime if you’re worried about getting a scrape or cut in a less-than-kosher subway car or on the travel, just use some antibiotic cream as a precaution.

Then, when the mood-ring bandage comes out, you’ll be able to tell your friends, “Hey, this place really is a hotbed for infection.” Afterwards, of course, you’ll want to get medical attention.
