With the introduction of Nanoelectronics and Microelectronics Science and Technology and the Possibility of Making Electrodes on a Very Small scale, it Became Possible to Make Nanometer Sensors.

In the aerospace industry, there is a need for self-guided nanochips and nanosensors to  be placed in the aircraft body as a fixed warning system and to determine when the aircraft needs repairs. In the automotive industry, nanochips and nanosensors can be used for optimal fuel consumption. Also, in expensive cars , these nanosensors can be used to improve  the state of the seat and the state of existing controls in accordance with different body states. In the next step,  it can be used in information technology to encourage the spread of always-on mobile computer computing systems.

Biological sensor or biosensor, and Test of care mode

Biosensor or nano biosensor is the name of a group of sensors. These sensors are designed to react with only one specific substance  . The result of this reaction is in the form of messages that a microprocessor can analyze. These sensors  are used to detect and quantify species in biological systems.

These sensors consist of three parts:

A)  Biological acceptor or bioreceptor: It is a biological element (antibodies, nucleic acids, enzymes, cells, tissues and other biological substances)  that can selectively react only with a specific substance.

b)  Detector and converter: which comes into action after the reaction of certain substances with biological receptors and can  determine the type and amount of reaction with different physical-chemical methods (for example, by examining electrochemical, optical, mass or thermal changes before and after reaction (and send to the processor by  appropriate signals).

C)  signal processors: which are mainly responsible for displaying the results and performing sensor calculations.

Biosensors have been the focus of many research centers in recent years. Since biosensors are powerful tools for identifying biological molecules, today they are used in various medical sciences, chemical industries, food industries, environmental monitoring, production

They use pharmaceutical, health, etc. products.

The human sense of smell and taste, which detects different smells and tastes, or the body's immune system, which detects millions of different types of molecules, are examples of natural biosensors. Biosensors  are most widely used in medical diagnostics and military sciences. The most common use of these multi-purpose sensors in military sciences and medical sciences, including the rapid diagnosis of diseases using rapid tests or Test of care, the characteristic of these tests is the speed and cheapness of the testing method. With the introduction of nanoelectronics and microelectronics science and technology and the possibility of making electrodes on a very small scale, it became possible to make nanometer sensors.
