Note: These synthetic nanosensors and gas nanosensors are prepared by attaching specific particles to the end of carbon nanotubes and calculating the vibrational frequency in the presence or absence of particles.

 These nanosensors are often used to detect and control chemical reactions by nanoparticles. The construction of gas nanosensors has been one of the most important topics in recent decades due to their many applications in various food, chemical,  health, military and even space research industries. Deadly gas leaks are one of the dangers of everyday industrial life. Unfortunately,  warnings in the industry are often too late to detect such leaks. Examples of such sensors are  made of taklia nanotubes about one nanometer thick and can absorb toxic gas molecules. They are also able to  detect a small number of deadly gas molecules in the environment. Such gas sensors have been successfully tested to detect ammonia and nitrogen dioxide,  which are toxic gases.

Metal oxide nanosensors have attracted much attention in the field of basic and applied sciences. These sensors are  mainly made of metal oxide semiconductors such as tin nano oxide, zinc nano oxide and copper nano oxide. The test sample of these sensors was  able to instantly detect ammonia and nitrogen dioxide molecules at a concentration of 20 ppm (ie 01 parts per million parts). These sensors will be used to detect war biochemical gases, air pollutants and even organic molecules in space  . Using these sensors, it is possible to detect very small amounts of chemical or viral contamination in agricultural, food and medical systems. Among these sensors, we can mention the sensor based on nanowires, which detects radiation damage in the medical and laboratory industries. These nanosensors are placed in blood cells. Also, the on-chip laboratory (LOC) is a device that consists of one or more laboratory operators  on a chip measuring a few millimeters or square centimeters and dealing with very small volumes of fluids and information.  It can give us a lot of examples from one example.



Conclusion : 

These sensors will be used to detect war biochemical gases, air pollutants and even organic molecules in space  .
