Biomaterials and Cartilage Laboratory (LBC)

Polytechnique Montréal, Montréal, Québec
What the facility does

Use of biomaterials and nanoparticles for regenerative medicine and gene delivery

Areas of expertise

The laboratory's research activities focus primarily on the development of chitosan-based biomaterials and nanoparticles for regenerative medicine and gene therapy applications. The lab’s strength lies in the diversity and complementary nature of its cutting-edge infrastructure and its highly qualified personnel’s expertise and know-how. This combination enables in-depth physicochemical understanding  of biomaterials and nanoparticles and their biological activity. The lab’s facilities and equipment include a histology lab, a molecular biology lab, a confocal microscopy room, an environmental scanning electron microscope, a flow cytometer and steric exclusion chromatography devices. Tangibly, the lab’s activities cover the following areas :

  • Production, characterization and modification of medical-grade chitosan;
  • Development of theoretical tools to predict the behaviour of chitosan in solution;
  • Preparation and characterization of nanoparticles for nucleic acid delivery;
  • Development of hydrogels for tissular repair;
  • Nanostructure visualization by environmental scanning electron microscope;
  • In-depth study of the effects of nanoparticles in vitro, by means of advanced cellular biology, molecular biology and confocal microscopy techniques;
  • Full histological preparation and detailed analysis of animal study tissues;
  • Mechanical characterization of biomaterials and biological tissues.
  • The lab has an internal quality assurance service applicable to good fabrication lab practices. Research work has led to the commercialization of a product used to repair joint cartilage (BST-CarGel®, Piramal Healthcare Canada).
