A novel method to measure the total serum protein concentration is described in this paper. The method uses a tapered fiber optics based on the principles of fiber optic evanescent wave spectroscopy. The biosensor applies a commercially available fluorescent dye-immobilized porous glass coating on a multi-mode optical fiber. The evanescent waves at the fiber optic core-cladding interface are used...
