<p>Abigail Lytton-Jean&nbsp;is&nbsp;the visionary and core director of the Nanotechnology Materials Lab at the Koch Institute for Integrative Cancer Research at MIT. Her lab addresses nano and materials characterization of bio-relevant materials with a strong emphasis on cryo electron microscopy. Of particular significance are the sample preparation and cryo workflows that&nbsp;make possible&nbsp;correlation between light and electron microscopy. This allows for the orchestration of multiscale imaging&nbsp;of&nbsp;a group of cells or tissue while providing pinpoint accuracy of desired regions with nanometer and subnanometer resolution. Dr&nbsp;Lytton-Jean&#39;s background is founded in bio and nanomaterials research. She conducted her graduate studies with Professor Chad Mirkin at Northwestern University and her postdoctoral work with Professors Robert Langer and Daniel Anderson at Massachusetts Institute of Technology.</p>

Collection Overview

In 2017 the Nobel prize in chemistry was awarded "for developing cryo-electron microscopy (cyroEM) for the high-resolution structure determination of biomolecules in solution." The field has quickly responded with a flurry of growth. Critical to the success of cryoEM is sample preparation and advanced image processing which have experienced a surge in new developments, as well. These include new workflows, correlation between imaging modalities, sample preparation techniques, workflow automation, data processing (including application of deep learning segmentation), and a rekindling of interest in existing techniques that are no longer widely practiced. These methods, routines, and techniques are intensively hands-on by nature, often involving great precision and user input/intervention over many steps. Frequently a single mistake early in the workflow is only identified during the final imaging or analysis steps, leading to lengthy troubleshooting in the hands of the uninitiated. This collection seeks to invite experts in the field to submit new methods, software routines, or detailed walk-throughs of existing approaches that will help document these processes, leading to better dissemination of methods to the rapidly expanding research community.
