A fluorescence-based optical sensor includes a membrane immobilized fluorophor secured to one end of a bifurcated fiber optic channel for exposure to the sample to be analyzed. The fiber optic channel also has an input end coupled to a radiation source arranged to supply radiation at two different wavelengths and an output end coupled to a bandwidth limited photosensor. The radiation source alternately excites the fluorophor at a first wavelength that excites an acid form of the fluorophor and at a second wavelength that excites a base form of the fluorophor, and a ratio of the resulting fluorescence intensities is taken as a measure of a characteristic of the sample being analyzed.

A dry analytical element is disclosed which can be used to sensitively and rapidly detect and quantitate protein. The assays are carried out using a dye that reacts with protein and molybdate ion to produce a measurable change in the spectral absorption of the dye. Also disclosed are polymers which stabilize and enhance the accuracy of the assay based on acrylamide, and compounds which reduce interference by bicarbonate.
