Nano Laboratory on a Chip (LOC) is a Nano Electrical Device That Consists of One or More Laboratory Agents on a Nano Chip With Dimensions of Several Nanometers

These synthetic nanosensors and gas nanosensors are prepared by attaching special particles to the ends of carbon nanotubes and calculating the vibration 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. 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 single-layer 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. These sensors will be used to detect bio-chemical war gases, air pollutants and even organic molecules in space
