Head of Research: Daniel Côté

This sector is experiencing strong growth and has become one of the most rapidly developing axes at our research centre. The main activities underway target imaging, diagnostics, the development of analytical tools and therapeutics. Work in this sector is supported by various partnerships with hospital-based research centers, in particular the Quebec University Institute of Mental Health, the organization that collaborated with the COPL in obtaining a second Canada Excellence Research Chair, this one in neurophotonics. The Chairholder is Dr. Pierre Marquet who joined the COPL in 2015.

Biophotonic probe
Several types of bacteria move around in their environment with the aid of long filaments called flagella. Bacterial flagella measure no more than 20 nm in diameter but can be observed with fluorescence microscopy. Here the genetic code of E.coli bacteria was modified to allow a fluorophore (Alexa Fluor 488) to be specifically attached to the filament's protein.
In vitro setup for in-depth study of the bacterial flagellum. Here a micropipette with an internal diameter of approx. 1 µm grasps an E.coli bacterium. Ultrafast laser pulses pierce the bacterium's membrane enabling access to the core of the cell as well as direct control of the flagellum's motor. The motor's rotation can be observed with high-speed fluorescence microscopy.
