WebFiber-optic biosensors (FOBS) are optical fiber-derived devices which use optical field to measure biological species such as cells, proteins, and DNA. Because of their efficiency, accuracy, low cost, and convenience, FOBS … WebThis critical review emphasizes both the biological and transduction aspects of optical immunosensors. The basic concepts of antibody-antigen interactions in solution are reviewed, and factors affecting the kinetics at the solid-liquid interface are characterized.
