Got this result in Google News:

https://optics.org/news/12/6/4

A metamaterial can be used together with an optical microscope, and
apparently a computer to combine the images obtained, to view living cells
under ordinary light, and yet get images with a resultion heretofore only
attainable in electron microscopes.

Thus, living cells, that can't be placed in the environment of an electron
microscope, can now be examined at higher resolution.

This is exciting news in itself, but it also made me wonder if this might
not be an alternative to the use of EUV lithography in making integrated
circuits.

Metamaterials are interesting, agreed. They don't live up to their hype
100%, but then neither does anything else. ;)

Probably hard to do in litho. The metamaterials I know about rely on
surface plasmon behavior in metals, which doesn't occur in the UV.
