The wonders of graphene are numerous—it can enable flexible electronic components, enhance solar cell capacity, filter the finest subatomic particles and revolutionize batteries. Now, the “supermaterial” may one day be used to test for amyotrophic lateral sclerosis, or ALS—a progressive, neurodegenerative disease which is diagnosed mostly by ruling out other disorders, according to new research from the University of Illinois at Chicago published in ACS Applied Materials & Interfaces.
