DOI: 10.1364/ol.463866

Abstract: Nanograting-based plasmonic sensors are capable of real-time and label-free detection for biomedical applications. Simple and low-cost manufacturing methods of high-quality sensors are always demanding. In this study, we report on a one-step etch-free method achieved… read more here.
