ABSTRACT:
An optical assay apparatus having an optical filter, an optical sensor with a light ray redirection portion and an assay sensing portion, and a filter to block certain wavelengths of excitation light rays and to pass certain wavelengths of signal recovery light rays from the optical sensor. A method for performing an assay that includes providing at least one assay station, moving the optical sensor into position over a respective fluid in at least one assay station, immersing the assay sensing portion in the respective fluid, and removing the assay sensing portion from the respective fluid.
