The structure of bacterial cells provides crucial clues about their interaction with their host. What are the key structural features of a bacterial cell that determine pathogenicity? What roles do these structures play in the life cycle, and how do they change during the infection process?

Can we determine the 3D structure of a chemotaxis core complex using single-particle reconstructions via cryo-EM?

Cryogenic electron microscopy (cryo-EM) is a powerful technique used to visualize the inside of cells and to study specific protein complexes. Within this thesis, I describe the use of various cryo-EM techniques to gain insight into the structural changes of the human pathogen, Vibrio cholerae, as it…

This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process.

X-Ray Diffraction (XRD), Nuclear Magnetic Resonance (NMR) and Cryo-electron microscopy (Cryo-EM) are the three main methods for solving structures of macromolecules.

Bacterial chemosensory arrays are protein assemblies that are the key structural and functional component for motile bacteria to sense their internal or environmental chemical signals.

A new executive board has been installed at NeCEN, a state-of-the art facility that offers the most advanced cryo-electron microscopes worldwide. The new board members are full of excitement: what are their ideas for the future of the facility?

Researchers need to work in specialized environments when they work with dangerous bacteria and viruses. These microbes spread easily, so only in labs with a high biosafety levels they can be studied. Unfortunately, to look at the microbes properly, expensive microscopes are needed that are not always…

The European Union has invested ten million euros in the so-called iNEXT-Discovery consortium. The goal of this new consortium is to enable European researchers to extend innovative structural biology research. The Netherlands Centre for Electron Nanoscopy (NeCEN) is also part of iNEXT-Disovery, which…

Chinese and Leiden scientists came together in Leiden to study the intricacies of modern visual techniques.

On 21 March The Netherlands Centre for Electron Nanoscopy (NeCEN) hosted the Life Sciences Café. Around 60 people from neighbour companies from the Leiden BioScience Park visited the facility for cryo-electron microscopy to get a glimpse behind the scenes. Head of NeCEN Ludo Renault believes it was…
