Note: Types of electromagnetic nanoparticles can be used in biosensors. And in order for magnetic nanoparticles to have biological applications , they must be biocompatible and biodegradable.
In fact, biosensors are analytical tools that can use the intelligence of biological materials to identify and react with compounds or compounds . The product of this reaction can be a chemical, optical or electrical message. Many biosensors used for biological applications are capable of capturing Ca, etc., and detecting parameters such as temperature, pressure, pH . In addition, they can be used as a biological 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 biological materials, has a biological nature . This element must be connected to a converter Converters (nanobio sensors) 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 to the attractive properties of nanomaterials, it paves the way for a wide range of electrochemical sensors that improve analytical power .
Nanotechnology has had a profound effect on nanosensors, so that it is now possible to produce a variety of nano-materials with controllable size, shape, surface load, and desirable physical properties. The potential for use as a non-invasive diagnostic tool and the combination of multiple methods in a probe are two major advantages of nanomaterials that can be mentioned. All of these factors cause high sensitivity in them and deeper knowledge of environmental processes. The ability of nano-biosensors to detect nano-bio-biology and features such as sensitivity, flexibility and functionality of this sensor can be used as a new model in analytical and clinical tools. Nanomaterials are usually sensitive to nanotechnology Elevated electrochemical or nanobiological. Among the developed nanomaterials, structures such as carbon nanotubes (CNTs), silicon nanoparticles (SiNWs) and conductive polymer nanotubes (CPNTs) are significantly used in the construction of sensitive sensors.
Conclusion:
In the case of nanobiosensors, the critical dimensions are directly related to the performance of the biosensor measurement, such as the next one that controls the amount of surface available to chart diagnostic elements , or the next one that measures the strength of a signal in nanochemical biosensors . Or the available level that detects the formation of complexes between the identifier elements and the target analyzes in the biosensors with mechanical converters . Structures such as nanowires, metal nanoparticles, magnetic nanoparticles, single-hole plates, and carbon nanotubes can be used to measure nanochemicals because of their unique nanotechnical, optical, and magnetic properties .
