Spectral confocal microscopy was used to visualize neurons using silver and gold cell labeling. The development enables imaging of archived tissue samples, which could aid long-term clinical research efforts and the diagnosis of cancer and neurological disorders. Staining neurons with silver began in the 1800s, and now researchers at the University of Minnesota and Agnes …

A miniaturized hyperspectral device was developed as an add-on to a standard camera and could be used to reuse a camera to generate hyperspectral images and video for a range of applications. The device uses compressional sampling techniques to capture signals and images from far fewer samples or measurements than the traditional sampling theorem that …
