We are also a member of uOttawa's Nexus for Quantum Technologies (NEXQT) Institute.

What we do

We combine materials chemistry with physical and biomedical aspects to design and study novel lanthanide-based nanophosphors as multifunctional nanocarriers for near-infrared based bioimaging and energy conversion technologies.

  • August 2024 - Congratulations to Hudson A. Bicalho and team from the Howarth Lab (Concordia University) for their paper on lanthanide-based MOFs. Thanks for including us in this study, now online at Chemistry A European Journal!
  • 21 June 2024 - Jeremy Doucette, étudiant diplômé, parle à Radio Canada de notre projet avec les Dr Nicolas Bordenave, Maria DeRosa et Riadh Hammami. Entendre parler des nanoparticules dopées au lanthanide (ainsi que des biscuits et des chocolats !) pour des applications biomédicales: "La recherche : La modification de surface des nanomatériaux aux lanthanides" (http://tiny.cc/lanthanides) 
  • April 2024 - What happens if we make Ln-NPs very small and dope them with a single Er3+ ion? Can the Murugesu-Lab observe single-molecular-magnet-like behavior? They can! Collaborative work with Drs. M. Murugesu, J. Moilanen, and X. Li just published in Nature Communications! Congrats to the team!  ​
