We have demonstrated that output grating couplers on thin Si02-TiOz waveguides are sensors which respond (i) with sub-monomolecular sensitivity to the adsorption of molecules out of a gaseous or liquid sample covering the waveguide in the grating region, and (ii) to changes in the refractive index o
We demonstrated the feasibility of using integrated optical output grating couplers in direct immunosensing. We monitored as functions of time, first the adsorption of an antigen (Ag) on the waveguide's surface, and subsequently, the binding of the corresponding antibody (Ab), i.e. the formation of
