Paper Abstract

We present a novel sensing architecture consisting of a two-core transversally chirped microstructured optical fiber (MOF) suitable for label-free detection of molecules. The air holes of rings surrounding one core of the structure are functionalized for antibody detection by immobilization of an antigen sensor layer onto the walls of the holes. The change of the layer thickness of biomolecules can then be detected as a change in the device transmittance. Numerical calculations indicate that this novel structure can achieve acceptable level of sensitivity whereas the biosensor is mm long.
