Executive Industry Relevance

Microcrystal electron diffraction (MicroED) enables rapid, atomic-resolution structure determination of small molecules directly from nanocrystals, addressing a key bottleneck in pharmaceutical discovery. This capability enhances predictive confidence in early-stage compound characterization and accelerates the transition from chemical synthesis to structural validation. MicroED's compatibility with standard cryo-EM infrastructure positions it as a scalable, enterprise-ready solution for portfolio-wide structural elucidation.
