It now appears that there is no fundamental limit in achieving ... microscopy), which rely on much shorter wavelengths than visible light. The arrival of super-resolution optical microscopes ...

The limit of resolution of the transmission electron microscope is now less than 1 nm. The TEM has revealed structures in cells that are not visible with the light microscope.

The diffraction limit restricts the spatial resolution of optical microscopes, making it challenging to observe structures smaller than approximately half the wavelength of the illuminating light.
