Review of Biosensors in Industrial Process Control

摘要

This paper presents an overview of biosensors used for industrial process control. The review was performed on twenty selected papers. Two widely used biosensors were analyzed: the biosensor for glycerol detection and the biosensor for detection of antibiotic residue in milk. In the case of glycerol detection, using whole bacterial cells of Gluconobacteroxydans showed highest sensitivity. In addition, an amperometric biosensor with gold electrode based on enzyme glycerol dehydrogenase with added diaphorase immobilized in polycarbamoyl sulfonate hydrogel showed appreciable results. For antibiotic detection, the parallel affinity sensor array, based on antibody binding, showed the best performance characteristics, with the detection limit of 0.12 μg/L for certain antibiotics.
