Note: An  electrochemical nano biosensor  is a device that provides direct information about the chemical composition of its environment and presents it to us in the form of an electrical, optical, etc. signal. 

The operation of a chemical nanosensor in the detection process is similar to that of the human nose; Chemical sensing methods are considered one of the modern and advanced nanoelectronic techniques today. These methods are part of the information acquisition process in which information about the chemical nature of the surrounding environment is provided instantly. In this process, an amplified electrical signal is generated as a result of the presence and interaction of a chemical particle with a sensing layer. Therefore, chemical sensing consists of two main and key steps, which are detection and amplification. The device that performs the above process is called a chemical sensor. 



The main part of an  electrochemical  nano biosensor  or biosensor is its sensing element. The sensing element is in contact with a detector. This element is responsible for recognizing and binding to the species of interest in a complex sample. The detector then converts the chemical signals produced as a result of the binding of the sensing element to the species of interest into a measurable output signal. Biosensors rely on biological components such as antibodies. Enzymes, receptors, or whole cells can be used as the sensing element.



Using these sensors,  electrochemical nano biosensors,  it is possible to detect very small amounts of chemical contamination or viruses and bacteria in the agricultural and food system. Research  in the field of nanodevices is part of the world's current scientific research. 

Conclusion: 

An  electrochemical nano biosensor  is a device that provides direct information about the chemical composition of its environment and presents it to us in the form of an electrical, optical, etc. signal.
