Note: The way a chemical nano sensor works in the detection process is similar to the human nose; chemical sensing techniques are nowadays considered as one of the modern and advanced nanoelectronics techniques.
These methods are part of the acquisition information process where information about the chemical nature of the environment is provided in an instant. In this process, an amplified electrical signal is generated as a result of the existence and interaction of a chemical particle with a sensing layer. Therefore, chemical sensing consists of two main and key stages, namely detection and amplification. The device used to perform the above process is called a chemical sensor. A chemical sensor is a device that provides in-depth information about the chemical composition of its environment and provides it in the form of an electrical, optical signal, and so on.
This device includes a chemical tank and a physical converter. Terrain may be exemplified by a human nasal chemical sensor in which the process of detecting and subsequently producing and amplifying (nerve) electrical signals is carried out. Various types of chemical sensors have been used for the control of diabetes in various cases to detect and measure gases such as carbon dioxide and a number of other gases. Environmental sensitivity measurements have been widely used to determine various metal and nonmetallic contaminants of chemical sensors. Other applications of these applications include process control in food and fermentation industries, the method of nanosensor fabrication and its importance on cell-gel film, and how to modify the chemical to make it more sophisticated and sophisticated. The spectrophotometric detector and the variable effects of concentration and inactivation are described. In this study, we try to introduce a new type of chemical sensors (chemical nanosensors).
Due to the importance of pH measurement in acidic media, the following system was used as a sensitive film preservative prepared inside a TB spectrophotometer to insert a sol-gel membrane inside it. The safranine O reagent, which is chemically labeled on a sol-gel transparent film, is used as an optical nitrite sensor. In the preparation of the above nanosensor, the effect of various factors such as how the film is fixed on the film, the effect of the fixation time on the film, and also how the film structure is studied, and finally, the single-factor method is used for optimizing the parameters. Only the desired parameters are changed.
Conclusion Chemical nano-sensors
The structural similarity of several sensors built at the same time is called reproducibility, and the similarity between sensors built on separate frequencies implies reproducibility. Nitrite is measured by high-speed nanoparticles made with sol-gel film and high sensitivity by saffronin O. Safranin O binds to the covalent bond in the sol-gel membrane and is a very good binding type. The optical properties of safranine O attached to sol-gel membranes have been shown to be a function of nitrite concentration in the environment, the adsorption changes for safranine O in the range of pH = -2 are linear and for the fast sol-gel membranes . . The adsorption rate for safranine O is 520 nm on the sol-gel film and is now intensifying the covalent bonding It plays a crucial role between the narrator and the film. When the reagent is labeled on the sol-gel, it acts as an oxochrom and causes a change in the maximum wavelength.
