From: Label-free super-resolution imaging of adenoviruses by submerged microsphere optical nanoscopy
Images of adenovirus clusters. (a) An SEM image showing the place of interest. (b) An optical microscope image of a 100-µm BaTiO3 microsphere aligned on top of adenovirus clusters. (c) High magnification of SEM image of adenovirus clusters. (d) The low magnification SMON image of adenovirus clusters (100-µm BaTiO3 microsphere coupled with a 50× objective lens, NA=0.75). (e) A higher magnification of SEM image of adenovirus clusters. (f) A higher magnification SMON image of adenovirus clusters (100-µm BaTiO3 microsphere coupled with an 80× objective lens, NA=0.9). SEM, scanning electron microscopy; SMON, submerged microsphere optical nanoscopy.
