Data Collection Service For Nano Crystals
Rigaku offers a crystal structure determination service with scientific support, with data collection on a XtaLAB Synergy-ED diffractometer in Rigaku's own laboratories.
Access our electron diffraction service delivering all structural information, datasets, raw data files and software to re-process at your own leisure. Electron diffraction can be carried out on samples with crystallites under 1 micron in size, meaning that crystallization trials for traditional X-ray analysis no longer have to become a bottle neck to structural analysis.
What you will receive:
- Full experiment(s) with frames.
- CrysAlisPro ED data processing software
- AutoChem enabled datasets for automatic structure solutions.
- Initial structure solution model
- Help with description of experimental section regarding XtaLAB Synergy-ED data will be provided.
- Access to expert applications team for data processing support
- Complimentary access to Rigaku’s electron diffraction forum
- Cryo transfer available for hydrated or solvated samples

Notable papers
- 3D Electron Diffraction: The Nanocrystallography Revolution by Mauro Mauro Gemmi, Enrico Mugnaioli, Tatiana E. Gorelik, Ute Kolb, Lukas Palatinus, Philippe Boullay, Sven Hovmöller, and Jan Pieter Abrahams.
This article reviews most important 3D electron diffraction (3D-ED/MicroED) applications for different kinds of samples and problematics, related with both materials and life sciences.
- Electron diffraction determines molecular absolute configuration in a pharmaceutical nanocrystal by Petr Brázda, Lukáš Palatinus and Martin Babor
- Chirality and accurate structure models by exploiting dynamical effects in continuous-rotation 3D ED data by Paul Klar,Yasar Krysiak, Hongyi Xu, Gwladys Steciuk, Jung Cho, Xiaodong Zou, Lukáš Palatinus
Determination of the absolute configuration of organic molecules is essential in drug development and the subsequent approval process. In Brázda et al. it was shown for first time, that this determination is possible through electron diffraction using nanocrystalline material, making use of dynamical diffraction effects.
Building upon this ground-breaking result, in Klar et al., it is demonstrated that significant improvement of refinement quality and determination of absolute structures via dynamical diffraction can be applied routinely to a wide range of sample classes.
- Microcrystal electron diffraction in macromolecular and pharmaceutical structure determination by Max T. B. Clabbers, Hongyi Xu
- MicroED for the study of protein–ligand interactions and the potential for drug discovery by Lisa J. Clark, Guanhong Bu, Brent L. Nannenga & Tamir Gonen
The review papers by Clabbers et al. and Clark et al. specifically discuss the new opportunities opened up by 3D-ED/MicroED for drug discovery, fragment screening, and study of protein-ligand complexes
- Can 3D electron diffraction provide accurate atomic structures of metal–organic frameworks? by Zhehao Huang, Meng Ge, Francesco Carraro, Christian Doonan, Paolo Falcaro and Xiaodong Zou
Mesoporous framework structures pose a particular challenge for crystallographic structure determination due to their small crystal sizes and high radiation sensitivity. These issues can be readily overcome by 3D-ED/MicroED, which has been shown for the example of a metal-organic frameworks in the article by Huang et al.
- Towards automated diffraction tomography: Part I—Data acquisition by U.Kolb, T.Gorelik, C.Kübel, M.T.Otten, & D.Hubert
- Collecting 3D electron diffraction data by the rotation method by Daliang Zhang, Peter Oleynikov, Sven Hovmöller and Xiaodong Zou
- Three-dimensional electron crystallography of protein microcrystals by Dan Shi, Brent L Nannenga, Matthew G Iadanza, Tamir Gonen
- A Medipix quantum area detector allows rotation electron diffraction data collection from submicrometre three-dimensional protein crystals by I. Nederlof, E. van Genderen, Y.-W. Li and J. P. Abrahams
The foundations of modern 3D-ED/MicroED techniques have been laid by groups from, among others, Mainz, Stockholm, HHMI Janelia and Leiden, who creatively combined approaches from electron microscopy and single-crystal X-ray diffraction. These publications from the early days of 3D-ED/MicroED present their ground-breaking research.

Micro-ED is new emerging field that is game changer in structural characterization, especially in pharmaceutical field. In our field, it is not uncommon that we have form that is unstable, cannot be made as single crystal, etc while having crystal structure is unequivocally important for project decision. We used to solve the structure from PXRD data, but access to synchrotron and time needed to solve and refine the structure are sometimes not suitable for early drug development where speed matters.
Rigaku is forefront in making instrumentation for MicroED and development of Synergy ED is a real game changer. I have been working with different companies offering MicroED, and so far Rigaku provides the best support and data with the quickest turn around. The service is exceptional! The service is also a good way to provide real case to acquire this capability in-house or with the collaboration with local partner.
