Note: The main part of an electrochemical or biological nanosensor is its sensor element. The sensor element is in contact with a detector. This element is responsible for identifying and linking to the species in a complex specimen.

The detector then converts the chemical signals generated by the bonding of the sensor element to the target species into a measurable output signal. Biosensors rely on biological components such as antibodies. Enzymes, receptors, or whole cells can be used as sensors.



Nanosensors are classified into different types. One of these categories is based on the shape of nanoparticles and their application as follows:

A.  Nanostructured Materials: Like porous silicon, nanosensors made from these materials are used to detect chemical and biological reactions.

B -  Nanoparticles: such as nanoscale spherical materials that are used as optical-biological, optical-chemical receptors and space image sensors  Like nanosilicon particles that are used as biosensors. Nanosensors can also be divided into three categories based on their structure:  quantum dots, carbon nanotubes, and nanodevices.


Using these nano-sensors (nano-biosensors) it is possible to detect very small amounts of chemical contamination or viruses and bacteria in the agricultural and food systems. Research  in the field of nanomaterials is one of the most up-to-date scientific researches in the world. With the advent of nanoscience and nanotechnology and the possibility of making electrodes on a very small scale, the construction of nanometer sensors became possible. These  sensors having a size of nanometer and their application environments, Nanvbyvsnsvr) nanosensor bio (named. Nanosensors  biological electrodes are very small in size nm and cell size, which through consolidation of certain enzymes on their surface, to  detect chemical species Or biologically sensitized cells, from these nanosensors to detect and quantify species in Biological systems are used. This technique is a very useful way to detect the passage of certain molecules through a cell wall or membrane.



Conclusion :

The main part of a nano-electrochemical or biosensor is its sensor element. The sensor element is in contact with a detector. This element is responsible for identifying and linking to the species in a complex specimen.
