What is X-Ray Crystallography?
A technique for determining the atomic structure of crystalline materials by analyzing X-ray diffraction patterns. When X-rays interact with the crystal lattice, they diffract at specific angles described by Bragg's law. Used to determine the structures of proteins, DNA, and inorganic materials.

X-ray crystallography has determined the structures of thousands of proteins, nucleic acids, and small molecules, transforming biology and drug design. It confirmed the double helix structure of DNA. Pharmaceutical companies use crystal structures to design drugs that fit enzyme active sites precise…
X-ray crystallography uses ionising X-radiation requiring appropriate shielding of the instrument. Many protein crystals require cryogenic conditions using liquid nitrogen, which is an asphyxiation hazard in confined spaces.
