CryoWrite is a Swiss-based biotech company, and start-up company from the University of Basel. The vision of cryoWrite is to accelerate structure based drug design, by improving the protein structure determination workflow. The cryoWriter is our first tool to reach this goal: a robot for cryo-EM sample preparation that addresses a main bottle neck for structure determination by cryo-EM.
Cryo-EM is today’s fastest growing method to determine the atomic structure of biomacromolecules. The determination of the tertiary protein structure protein at atomic resolution to accurately study protein folding and side chains conformation has been dominated by X-Ray analysis of three-dimensional crystals. In the last decade, cryo-EM methods made impressive progress, benefitting from improved hardware and software. Consequently, cryo-EM has evolved to one of the structural biologist’s driving methods for structure determination, as indicated by an exponential growth of atomic structures solved by the single-particle analysis approach and entered into protein databank.
Importantly, the single-particle approach allows structure determination of proteins without crystallization. As a result, cryo-EM is mainly complementary to X-ray methods, especially for large proteins and complexes that are difficult to crystallize. cryo-EM can thus provide structural information on the structure of biomolecules that are otherwise inaccessible.
One bottle-neck in the cryo-EM workflow that has remained, is the sample preparation. cryoWrite has developed unique microfluidic methods for protein isolation, sample preparation, and nano-analytics to overcome this remaining hurdle. Our cryoWriter’s unique combination of automation, microfluidic protein purification, and loss-free (i.e. without blotting) nanoliter grid writing opens new avenues for efficient and reproducible sample preparation to leverage cryo-EM technology.
Founders
Andreas Engel, PhD, Prof. Em.
CSO
Andreas holds a PhD in physics. He worked on laser physics and holography before joining the Biozentrum Basel. He pioneered STEM and AFM imaging in biology and initiated the Nanoscience Curriculum. After retiring from the University Basel, he was appointed at the Case Western Reserve University in Cleveland and later at the University of Delft for cryo-EM of membrane proteins.
Thomas Braun, PhD
Board member
Thomas is a trained biophysicist. During his PhD, he studied membrane proteins by electron microscopy. Later, he worked on nanomechanical sensors. Thomas and his graduate students work on combining microfluidics of the cryoWriter with electron microscopy, focusing on single-cell proteomics to study neurodegenerative diseases.
Hans-Andreas Engel, PhD
President of Board
Hans-Andreas’ background is in theoretical physics and quantitative finance. His academic and entrepreneurial achievements range from a Science publication to starting various profit-generating operations. In addition, he is active as a business angel in over ten startups. Further, he is experienced in building robust and complex IT infrastructure automation and real-time data processing. At cryoWrite, he can leverage these skills and work on strategic planning, business decisions, physics modeling, and software architecture.
CEO
Patrick Frederix, PhD
Patrick studied applied physics in Eindhoven (Netherlands) and has a PhD in optical microscopy. After moving to Switzerland in 2001, he joined the lab of Andreas Engel in the Department of Structural Biology of the Biozentrum in Basel. He started working for Nanosurf AG in 2010, where he became head of applications and services, and was part of the extended board. In October 2023, he became successor of Andreas Engel as CEO of cryoWrite.
