Graphene Sensor (IMAGE) University of Illinois Chicago Caption An illustration of the graphene-based COVID-19 spike protein detection process developed at UIC. The white rectangle represents the substrate with graphene functionalized with SARS-CoV-2 antibody (shown in yellow). When this graphene detector interacts with the virus' spike protein in a COVID-positive sample, its atomic vibration frequency changes.
