The Netherlands Centre for Electron Nanoscopy (NeCEN) is the open access research facility for cryo electron microscopy in The Netherlands and offers research institutes and companies, both Dutch and international, access to advanced cryo electron microscopy and expertise. The cryo electron microscopes at NeCEN are specifically designed to explore complex biological structures.
Between 2007 and 2011 experts from eleven organizations in the Netherlands worked closely together in a consortium to realize the NeCEN. In 2012 it opened its doors. Today, after several changes in its organization, NeCEN is embedded within the Leiden Institute of Biology (IBL) as part of the Faculty of Science.
