Nanoscopy is the study of molecules and structures at the nanometre scale. Super‐resolution microscopy is often referred to as nanoscopy, because it uses fluorescence to specifically investigate molecules of interest at resolutions reaching down to 5 nm. Light microscopy was originally limited in resolution to around 250 nm, by the diffraction of light in the optical path. Super‐resolution, fluorescence‐based nanoscopy, allows optical microscopes to visualize the previously inaccessible nanoscale. This new technology poses a significant advancement for science and technology and was awarded the Nobel Prize in Chemistry in 2014.

The Nanoimager is the first desktop‐sized super resolution microscope commercially available.
