This article provides notes on biosensors. Biosensors are analytical devices that show potential for development in the clinical, diagnostic, food analysis, process control, and environmental areas. Examples of commercially available biosensors include enzyme electrode biosensors for detection of glucose in blood and single analytes in food, as well as biological oxygen demand (BOD) in waste water. Biosensors historically have been [...]
