Penn molecular scientists develop color-changing stress sensor

Posted On: August 18, 2011 - 9:00pm

It is helpful -- even life-saving -- to have a warning sign before a structural system fails, but, when the system is only a few nanometers in size, having a sign that's easy to read is a challenge. Now, thanks to a clever bit of molecular design by University of Pennsylvania and Duke University bioengineers and chemists, such warning can come in the form of a simple color change.
