WGM sensor is a photonic sensor embodied by a transparent spherical glass touching a pair of tapered optical fibers. The sensor detects whatever occurs near the surface of the glass sphere. For example, immobilizing a ligand onto the surface readily turns the sphere into a sensor that detects binding of target molecules. Attaching a layer that selectively partitions lead ions turns the sphere into a lead ion sensor.
