Note: The increasing growth of nanosensors Nanosensor has had a significant impact on human life. These sensors are a powerful tool for detecting biological molecules. Electrochemical methods are suitable candidates for this technology due to their simplicity, high sensitivity and desirable properties. The basis of this Nano bio sensor. Measurable electrical properties such as electric current, potential and ionic strength are dissolved in the solution.
In fact, nano biosensors are analytical tools that can use biological intelligence to detect and react with a compound or compounds. The product of this reaction can be a chemical, optical or electrical message. Many nano-biosensors used for biological applications are capable of Ca, etc. 2 + detection of parameters such as temperature, pressure, pH. In addition, they can be used as a bio-diagnostic system for substances such as enzymes, antibodies, antigens and microorganisms.
In general, biosensors consist of three basic parts. The sensor element, which responds to a biological substance, has a biological nature. This element must be connected to a transducer to produce a visible response. The converters themselves are divided into several categories, which are based on the received signals: electrochemical, optical, thermal
Piezoelectric and so on. The third part is the processor, which is responsible for displaying the signals converted by the converter. In addition, the attractive properties of nanomaterials have paved the way for the construction of a wide range of electrochemical sensors that improve analytical power. Nanomaterials are very useful for drug release applications and can lead to the development of new therapies through highly complex, sensitive and measurable chemicals. Their ability to identify specific cells and specific anatomical locations in the human body has led to their optimal use in nanosensor applications. The ability of nanosensors to detect specific cells or anatomical locations in the body in medical diagnosis and features such as sensitivity, flexibility, and the ability to shrink the sensor can be used as a new model in analytical and clinical tools. Elevated sensors by electrochemical or biological methods. Among the developed nanomaterials, structures such as carbon nanotubes (CNTs), silicon nanowires (SiNWs) and conductive polymer nanotubes (CPNTs) have been used extensively in the construction of sensitive sensors.
Conclusion:
The growing growth of nanosensors Nanosensor has had a dramatic impact on human life. These sensors are a powerful tool for detecting biological molecules. Electrochemical methods are suitable candidates for this technology due to their simplicity, high sensitivity and desirable properties. The basis of this Nano bio sensor. Measurable electrical properties such as electric current, potential and ionic strength are dissolved in the solution.
