Myriade is a French company created in 2017 that develops an innovative nanoscale imaging technology. Based on the works of the Langevin Institute, a French academic laboratory specialized in optical and ultrasonic technologies for life sciences, the technology Videodrop relies on a single-arm interferometric technique. It makes it possible to visualize without labeling living nanoparticles such as viruses, phages, or extracellular vesicles. The process was developed by Professor Claude Boccara at the request of the Professor Martine Boccara, specialist in virology, who was looking for a quick method to list viruses present in seawater samples collected during the Tara Oceans expedition in 2013. Myriade was born from the partnership between Quattrocento (Company builder, specialized in equipments for life sciences), Paris Sciences et Lettres, and the scientific team.
