Researchers successfully performed prolonged nanoscale optical imaging of micrometer-scale tungsten disulfide samples without signal degradation 

Optical nano-imaging techniques find immense applications in nanotechnology for visualizing nanoscale defects in samples. However, it is challenging to image large micron-sized samples at nanoscale resolution owing to signal distortions resulting from unavoidable thermal and mechanical drifts of the system over time. Now, researchers from Japan have developed an ultrastable nano-imaging system that successfully detects unique nanoscale defects not observed in conventional nano-imaging in micron-scale tungsten disulfide samples, widening the technique’s scope to biological samples.
