• Metamaterial to Aid Observing Living Cells

    From Quadibloc@21:1/5 to All on Tue Jun 1 13:49:10 2021
    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.
