Nanotechnology protein sensor created

Abstract:
U.S. researchers have developed a protein sensor that is so sensitive it can detect changes in concentration spanning more than five orders of magnitude.

Most biosensors rely on changes in the intensity of the fluorescence emitted, which is difficult to calibrate but Nicholas Kotov and colleagues at the University of Michigan have created a device in which the wavelength of the emitted light shifts reversibly.
