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 visualise 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.
