Fibre-fluorescence immunosensor based on evanescent wave detection
A fibre-optic sensor capable of detecting an immune reaction between fluorescently labelled antigens and antibodies bound at the waveguide surface is described. In a configuration where skew rays were detected, a signal level was found that made detection of a concentration of 10e9 M antigen possible. Keywork Fibre-optic sensor; Immune reactions The evanescent wave is a well known physical phen...
متن کاملThe critical sensor : a new type of
A new planar waveguide immunosensor has been developed in which adsorption at a surface, changing the refractive index contrast, is measured. In this "critical" sensor the change in the effective refractive index contrast is transducted to a shift of the critical reflection angle. The sensor's response after a specific binding of antigens to antibodies is discussed theoretically. In addition, a...
متن کاملA reusable evanescent wave immunosensor for highly sensitive detection of bisphenol A in water samples
This paper proposed a compact and portable planar waveguide evanescent wave immunosensor (EWI) for highly sensitive detection of BPA. The incident light is coupled into the planar waveguide chip via a beveled angle through undergoing total internal reflection, where the evanescent wave field forms and excites the binding fluorophore-tagged antibodies on the chip surface. Typical calibration cur...
