A group of scientists at the University of Wisconsin-Madison have shed light on a valuable new use for LEDs by demonstrating their usefulness as chemical sensors. In research published in the Jan. 25 issue of the journal Nature, the UW-Madison researchers illustrate how chemical exposure can alter the surface structure of LED materials, causing the intensity of the light to fluctuate.
Madison - Already glowing away on thousands of consumer electronics products, the light-emitting diode (LED) is proving to be a remarkably versatile material.
