Note: These synthetic nanosensors and gas nanosensors are prepared by connecting special electrical nanoparticles to the ends of carbon nanotubes and calculating the vibration frequency in the presence or absence of the particles.

 These nanosensors are often used to identify and control chemical reactions by nanoparticles. The construction of gas nanosensors has been one of the remarkable topics in recent decades due to their many applications in various food, chemical,  health, military and even space research industries. Leakage of deadly gases is one of the daily dangers of industrial life. Unfortunately  , the alarm systems in the industry often fail to detect such gas leaks very late. Examples of this type of sensors are made of  nanotubes with a thickness of about one nanometer and can absorb toxic gas molecules. They are also able to  detect a small number of molecules of deadly gases in the environment. Such gas sensors  have been successfully tested to identify ammonia and nitrogen dioxide gases, which are among the toxic gases.

Metal oxide nanosensors have attracted a lot of attention in the field of basic and applied sciences. These sensors  are mainly made of metal oxide semiconductors such as nano tin oxide, nano zinc oxide and nano copper oxide. The test sample of these sensors  has been able to instantly identify ammonia and nitrogen dioxide molecules at a concentration of 20 ppm (that is, 01 parts in a million parts). These sensors will be used to detect bio-chemical warfare gases, air pollutants and even organic molecules in space  .

synthetic nano sensors and LOC nanochip; in agriculture and medicine

Using these sensors, it is possible to identify very small amounts of chemical pollution or virus and bacteria in agricultural, food and medical systems. Also, among these sensors, we can mention a sensor based on nanowires that detects damage caused by radiation in the medical and laboratory industries. These nanosensors are placed in blood cells. Also, a laboratory on a chip (LOC) is a device that consists of one or more  laboratory operators on a chip with dimensions of a few millimeters or square centimeters and deals with very small volumes of liquids and  the desired information It can give us a lot from one sample.

Conclusion :

These synthetic nanosensors and gas nanosensors are prepared by connecting special electrical nanoparticles to the ends of carbon nanotubes and calculating the vibration frequency in the presence or absence of the particles.
