CLEM & FAST: From Research to Start-up

Announcement

The dissemination of emerging technologies to end-users is a key objective of FranceBioImaging. It is indeed essential that developers can obtain feedback from the end-users on their technologies. It is equally important that end-users can feed the thoughts and work of the developers. France BioImaging has thus invested in the dissemination of recently developed technologies in the Paris Centre node in the form of short videos.

The first two videos focus respectively on a fast-developing correlative imaging method that combines fluorescence microscopy and electron microscopy, and on a powerful reversible fluorescent protein labeling technology. These two technologies (as well as others currently developed in the Paris Centre node of FranceBioImaging) led to the creation of two start-ups (CryoCapCell and Twinkle Bioscience) thus illustrating another side of the dissemination action engaged by the actors of FranceBioImaging.

We are proud to present these videos created in collaboration with Picta Productions and the Paris Centre Node. Xavier Heiligenstein (Curie Institute) and Arnaud Gautier (ENS) present their research and their work, supported by France BioImaging in their inception.

This research has led to the creation of CryoCapCell, which develops and manufactures new products for sample preparation in the field of electron microscopy, such as the CryoCapsule and the HPM Light µ machine.

Research and development of the FAST technology is now undertaken through the startup Twinkle Bioscience. FAST offers new perspectives for cellular imaging, notably for high content screening or genome editing.
