Noninvasive methods for monitoring diabetes are being developed to eliminate the need for invasive finger-prick testing. Here, we propose the noninvasive detection of tear glucose using contact lenses that contain cerium oxide nanoparticles (CNPs). We chemically conjugated CNPs with glucose oxidase...
