Naccache Lab · Concordia University, Montréal
Luminescent nanomaterials for health, the environment and clean energy
We design carbon dots, inorganic nanoparticles and hybrid nanosystems, uncover their optical properties, and put that light to work in imaging, sensing, catalysis and energy.
About the group
Fundamental photophysics, practical problems
The Naccache group is based in the Department of Chemistry and Biochemistry at Concordia University’s Loyola Campus and is part of the Centre for NanoScience Research (CeNSR). We study how size, surface chemistry and composition control the way nanomaterials absorb and emit light, then use that understanding to build sensors, imaging probes, drug carriers, catalysts and materials for energy.
Our team brings together chemists, physicists, engineers and biologists, and we collaborate across Concordia and with partners in Québec, Canada and abroad.
Research
Five connected research directions
Nanomedicine & bioimaging
Carbon dots that light up cells, carry drugs and target cancer biomarkers.
Sensing & diagnostics
Fluorescent nanosensors for pollutants, pesticides and disease markers in breath.
Environment & water
Sustainable nanomaterials that capture and break down contaminants.
Clean energy & catalysis
Green catalysts for biodiesel, better lithium–sulfur batteries and solar nanocrystals.
Luminescence & materials under extreme conditions
Why nanomaterials glow, and how to keep them working in harsh environments.
Train with us
We welcome MSc, PhD, undergraduate and postdoctoral researchers from chemistry, physics, engineering and biology.
On the cover
Our research on journal covers
Selected cover articles from the group, from Nanoscale to Advanced Healthcare Materials.
In the lab
Chemistry you can see
Every colour here comes from a material made in our lab, excited by ultraviolet light. Tuning that colour, brightness and lifetime is what our research is about.
