1. A scanning sensing method comprising:
- coupling a removable substrate comprising a plurality of in-coupling waveguides, a plurality of out-coupling waveguides and combiners for coupling the in-coupling and out-coupling waveguides, wherein the substrate is coupled in optical communication with an adapter, a light source, and a detector to provide a scanning sensor system, wherein the adapter is coupled to the light source and the detector;
delivering a sample suspected of containing a biologically active analyte to be detected to an optical sensing site of the substrate, wherein the optical sensing site comprises a well;
providing a first light wave using a light source to one or more of the plurality of in-coupling waveguides of the substrate, wherein the in-coupling waveguides are in optical communication with the optical sensing site, wherein the first light wave is transducable by a sensor associated with the optical sensing site to a second light wave carried to an out-coupling waveguide; and
detecting the second light wave using the detector, wherein a measurable change in the first light wave as measured in the second light wave occurs when the sensor interacts with the biologically active analyte.
