Biosensors combine the selectivity of biology with the processing power of modern microelectronics and optoelectronics to offer powerful new analytical tools with major applications in medicine, environmental diagnostics and the food and processing industries.
What is a Biosensor? (1)
The term biosensor has been applied to devices either (1) used to monitor living systems, or (2) incorporating biotic elements. The consensus, however, is that the term should be reserved for use in the context of a sensor incorporating

Provides an example of using metabolic fluorophores (produced by the cells during the process) to monitor fermentations. The measured fluorescence signals are compared with cell concentration, protein concentration, and cellular activity.
