Super-resolution plasmonic imaging microscopy for a submicron tracking emulsion detector

A Nano Imaging Tracker (NIT) is a super-fine-grained nuclear emulsion that is capable of detecting an ionizing particle with nanometric resolution and recording the track by a line of silver nanograins of various shapes and sizes. The particle tracks need to be read out by some microscopic techniques; here we focus on the optical response of silver nanograins to realize a readout method beyond the diffraction limit. In this paper,...
