Abstract(s) :

(Anglais) The biomarker detection is an essential step for early cancer diagnosis. In that way, this work presents the development of an innovative plasmonic optical fiber immunosensor. A gold-coated optical fiber with a photoinscribed Tilted Fiber Bragg Grating (TFBG), embedded in a specifically designed packaging provides enough stiffness to penetrate into soft matters and human tissues. This biosensor is able to detect biomarkers thanks to the excitation of a surface plasmon wave. For the first time, we demonstrate the detection of a proteic target at very low concentration in hydrogels, what is an important milestone towards medical diagnosis.
