What is the upper limit of size for diffracting an object?

As far as I know the largest object that has been successfully diffracted is a oligoporphyrin molecule with a molecular weight of about $25000$. This was done on 2019 and is reported in Quantum ...

Diffraction proof

Two nothings is nothing. Reliably. So if you can pair each little virtual source with another that causes destructive interference you can be confident that when you add up the contribution from all ...

Difference between thin film interference and Bragg diffraction of electron

Promoted from a comment: Because the index of refraction at x-ray wavelengths for most materials is awfully close to 1.0, while the index of refraction in the visible can easily be 1.5 and above (1....
