In order to fulfill the potential of research from the fields of molecular biology and biochemistry, we use nanotechnologies and microfluidics processes. This multidisciplinary approach helps accelerate our research projects through the implementation of concepts generated by our teams of biologists and bioinformaticians. To accelerate the detection and identification of nucleic acids, we have developed a microfluidic system capable of handling volumes at the nanoliter scale. We also use nanostructures with silica surfaces to purify nucleic acids and magnetic nanoparticles coupled to antibodies, ligands or synthetic nucleic acids to capture, confine and purify the target nucleic acids and cells. Furthermore, some nanostructures have been invented to perform the amplification and detection of nucleic acids on biochips while enabling to simplify the devices used for these purposes. The use of such technologies also requires engineering expertise that we have gained in recent years. The outcome of such research projects usually results in prototypes of medical devices that may be subjected to technology transfer towards industrialization and commercialization.
