Main types of biosensors
Biosensor applications in the food industry

The biological activity of a compound with its substrate can be monitored in various ways, for example by oxygen or hydrogen peroxide consumption, fluorescence measurement, change in pH, temperature or mass... Many transducers have been used to develop biosensors. The nature of the transducer is often the basis for classifying different biosensors. The advantages and disadvantages of the different types of biosensors are listed in table 1 .
