Explain biosensor in environment monitoring

Answer»

hala MATE,


The idea for biosensors — using some part of an organism to generate a SIGNAL to MEASURE or monitor the presence of a substance — has been around for more than a century. The classic example is the use of canaries in coal mines to detect toxic gasses. Because these tiny BIRDS are so sensitive to these GASES that they would sicken long before the miners felt the effects, they served as a warning system.


hope this helps!!!!
