New dye changes bandage color if infection takes hold


Whenever you get a cut on your body some antiseptic cream and a plaster is usually the best course of action to keep it clean and let it stay protected while healing. For bigger wounds a bandage will be required, or even stitches and a longer period of time to heal.

One problem with covering wounds up is you don’t know if an infection has taken hold until you change the dressing. The act of changing the dressing can also be quite painful depending on where it is and what type of wound you have.

Researchers at the Fraunhofer Research Institution for Modular Solid State Technologies EMFT in Munich have come up with a solution to this problem. A new dye added to plasters and bandages will change color if an infection is detected. It works by reacting to the pH level of the skin. A value below 5 is normal and shows a wound that is healing or healed. Above 5 and something is wrong and an infection may have taken hold.

Using such a method of testing for infection could mean problems are spotted earlier and dressings have to be changed less often. Fewer people will have complications and in the end it could save both a lot of time and pain for the patient.

Tests are now going to be done in a hospital environment and then a commercial partner looked for. But the researchers aren’t just stopping at color-changing bandages. Optical sensors are being looked into which would allow for a precise pH level reading to be displayed as a digital output  rather than relying on a dye.

Things like this are awesome. They're just simple and helps people out instead of trying to make a profit for making stuff to help people.

From inventing MP3s, now to smart bandages, Fraunhofer is cool in my book.

I'd rather prevent the injury from even happening in the first place.

jeremy said...

yea hahaha this may be a bit expensive for a band aid consider you only need to take it off so see you have an infection.

It would take a lot of the tension out of most horror films - who's infected? The guy with the magenta boo-boo d'uh!

now this is cool, id never have to worry of infection again!

Zoy said...

Seems like a very simple design, that should perform its purpose well. Are you supposed to disinfect the wound after you remove the bandage, and before you put on a new one? I also read that you are supposed to let the wound breathe for awhile before applying another bandage?
