3D electron diffraction of protein nanocrystals: a new scenario in the field of crystallography

The research groups lead by Mauro Gemmi and Gianpiero Garau at the Center for Nanotechnology Innovation of the Istituto Italiano di Tecnologia located in Pisa (Italy), determined for the first time the structure of a new polymorph of a protein by collecting 3D electron diffraction data from single nanocrystals. Obtaining crystals of sufficient size in the micrometer range for diffraction data collection is well known to be the major bottleneck of protein crystallography, the most powerful methodology to investigate at atomic level how proteins and other biostructures are made, function and interact in living organisms. The IIT researchers demonstrated that also protein nanocrystals, obtained at the first stages of the crystallization process and invisible in optical microscopes, can be used for the characterization of protein architectures. This result opens innovative scenarios in the field of crystallography of biomaterials and discovery of novel drugs by structure-based design.

5DNanoPrinting has started!

The 5D NanoPrinting project has started with its first virtual kick-off meeting held in the IIT - Center for MicroBioRobotics in Pontedera the 21st of September. The goal of the project is to create an innovative technology for the rapid-prototyping realization of micro(nano)machines and components that will find several cutting-edge applications in fields like consumer electronics, automotive and healthcare. 5dNanoPrinting was granted a budget of 3.58 million euros under the EU’s Horizon 2020 FET Open Program. CNI is participating to the project with a team of researchers of the Electron Crystallography research line coordinated by Mauro Gemmi.
