Research Interest


Hedi Mattoussi Laboratory Page



Research areas: We focus on understanding, controlling and tailoring the interfaces between inorganic nanocrystals and biological (as well as non-biological) systems.  This requires making progress on few parallel tracks, including: nanoparticle design, structural and optical characterization, ligand design and characterization, chemical interfacing of QDs, Au nanoparticles and magnetic nanocrystals with biological systems, biosensing assemblies, in vivo imaging and sensing.



Research tools: synthetic organic and inorganic chemistry; 1H NMR; X-ray and light scattering techniques; TEM and SEM; Optical spectroscopy; energy transfer (FRET); FT-IR; Cell growth; Cell imaging.



Area 1: Design, synthesis and characterization of inorganic nanocrystals


Area 2: Design, synthesis and characterization of multidentate and multifunctional ligands


Area 3: Design of nanoparticle-bioconjugates as analytical tools for sensing, imaging and diagnostics
