En biologie, l’ensemble des avancées scientifiques et techniques sont fortement dépendantes des techniques d’observation des échantillons d’intérêt. En microscopie, la dernière avancée majeure fut l’invention du «nanoscope», qui permet d’observer l’intérieur d’une cellule avec une précision révolutionnaire. Cette invention fût récompensée du prix Nobel de Chimie en 2014 et elle commence à s’imposer comme la technique de référence pour l’ensemble des chercheurs en biologie. Malgré la puissance de cette invention, son utilisation reste complexe, laborieuse et peu reproductible. De ce fait, seule une poignée d’initiés dans le monde se sont équipés de ce type d’instrument. Depuis 2010, les laboratoires de l’ISMO et de l’institut Langevin développent une solution alternative permettant de résoudre ces problèmes. Pour valoriser cette innovation, Nicolas BOURG et Jean-Baptiste MARIE, jeunes docteurs en physique, ont décidé de s’associer pour créer l’entreprise Abbelight. Créée en mars 2016, Abbelight commercialise un ensemble de produits permettant à un utilisateur de transformer un microscope de fluorescence en nanoscope de manière simple et automatique.
