    Type I collagen is a major structural protein in mammals and shows highly structured macromolecular organizations specific to each tissue. This biopolymer is synthesized by cells as triple helices, which self-assemble outside the cells into fibrils (10-300 nm) that further form fibers, lamellae or other 3D networks. This assembly mechanism depends critically on the collagen concentration, as...

  2. 279. Single mode fibre transmission apparatus, measuring light where it counts

    Measuring fine loss in transmission of single mode fiber when coupled with 405nm laser light requires a sensitive apparatus as closed loop feedback systems are not commercially available. A stable laser and detector system are described which measure changes in transmission to within 0.02% change per hour over a 17-hour period. This measurement apparatus has proved useful in both...

  3. 361. Near-Infrared Excited Nanoparticles: Towards a Multimodal Platform
    Prof. Fiorenzo Vetrone (INRS-EMT, Université du Québec)
    17/06/2014, 14:30
    Division of Atomic, Molecular and Optical Physics, Canada / Division de la physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)
    Invited Speaker / Conférencier invité
    Near-infrared (NIR) excited nanomaterials are emerging as useful tools in diagnostic medicine and therapeutics. Excitation with NIR light mitigates some of the drawbacks associated with the use of UV as the excitation source. NIR light is silent to tissues thus minimizing autofluorescence, possesses greater tissue penetration capabilities and does not incur damage to the sample. In this regard...

  4. 137. Interferometric Second Harmonic Generation imaging of biological tissues
    Charles-Andre Couture (INRS)
    17/06/2014, 15:00
    Instrumentation and Measurement Physics / Physique des instruments et mesures (DIMP-DPIM)
    Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)
    Second harmonic generation (SHG) microscopy is used to image structures lacking a center of inversion (non-centrosymmetric). Some biological tissues, particularly those made of collagen, possess this property. Because SHG microscopy is a coherent technique, the structure of the studied sample influences greatly the generated signal strength. By varying the polarization of the fundamental beam,...
