Scientists at the Fraunhofer Research
Institute for Modular Solid State Technology EMFT
in Munich, Germany have developed an indicator dye that reacts to
different pH levels by changing colors, and incorporated it into a
This makes it possible
to check wounds without removing the dressing.
If a bandaged
area becomes infected, an indicator dye will simply change color from purple to yellow.
One of our writers covered the infection detecting dressings in another article in more detail.
Does This Look Infected?
Dr. Sabine Trupp, a scientist at the EMFT said, "We
have developed an indicator dye which reacts to different pH values, and
we have integrated it into a dressing and a plaster. Healthy skin and
healed wounds usually show a pH value of below 5. If this value
increases, it is shifting from the acid to the alkaline range, which
indicates complications in the healing of the wound. If the pH value is
between 6.5 and 8.5 an infection is frequently present and the indicator color strip turns purple," about the chemical reaction.
Where will EMFT go from here?
For now, the dressings will be used for a project at the dermatology clinic of the University of Regensburg.
More importantly, Dr. Trupp and her team at EMFT are currently looking for an industrial partner to commercially produce the bandages.
is an extraordinary opportunity for any entrepreneur who can put
together the industrial resources or who has the right vision.
