Note: Using these sensors (nanobiosensors), 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.

With the advent of nanoscience and technology and the possibility of manufacturing electrodes on a very small scale, it became possible to manufacture nanometer sensors. These  sensors were named nanobiosensors due to their nanometer size and their application in biological environments. Nanobiosensors  are very small electrodes in nanometer size and cellular dimensions that have been made sensitive to the detection of chemical or biological species of interest in cells by immobilizing specific enzymes on their surface  . These sensors are used to detect and determine the amount of species in  biological systems. This technique is a very useful method in detecting the passage of some molecules through the cell wall or membrane. Various sciences such as biochemistry, biology, electronics, various branches of chemistry and physics are present in the design of a nanosensor. The main part of a chemical or biological sensor is its sensing element. The sensing element is in contact with a detector. This element is responsible for identifying 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.

Nanosensors are categorized into different types. One of these categories is based on the shape of the 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 spherical nanoscale materials that are used as photo-biological, photo-chemical receptors and spatial image sensors  . Such as silicon nanoparticle that are used as biosensors. Nanosensors can also be  divided into three categories based on their structure: quantum dots, carbon nanotubes and nanodevices.

Conclusion: 

Using these sensors (nanobiosensors), 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.
