Note: One of the potential advantages of nanosensors over conventional sensors is their high sensitivity. The internal sensitivity of a sensor is defined as the ratio of the sensor's output signal to the change in sensor properties. The amount of analyzes connected to the sensor is defined. 


A high-sensitivity sensor is capable of rapid instantaneous changes. Sensitivity can also be defined as a sensitivity test that explains how a diagnostic test is able to identify a specific sample with or without analytics. Sensitivity in sensors affects some properties, including repeatability and diagnostic accuracy.



Dynamic range in nano-biosensors

Another parameter that is rarely discussed in the field of nanosensors is the dynamic range of the sensor. During this period, the sensor is able to generate an output signal that indicates the amount of analysis. The response sensor curve is linear and describes the range of analyte values ​​and output of the corresponding sensor  .




Dedicated performance in nanosensors

In addition to the ability to generate an output signal that indicates the presence of analytics, a sensor must be able to detect a specific analysis. This capability is called proprietary performance, and is a factor that allows the sensor to operate in an unobserved environment that contains large amounts of unknown substances. Despite the sensitivity, it is difficult to measure the performance of a dedicated nanosensor  because the number of materials that should not produce an output signal is very large. Dedicated performance is more commonly used when a sensor has to detect a small concentration of a certain analyte in an environment containing large amounts of non-target material  , many of which may be unattractively connected to the sensor and thus produce an abnormal signal  . .



Conclusion:

Gold nanoparticles have the ability to transfer electrons quickly and directly  between a wide range of electrophoresis materials  They also provide light scattering properties and the ability to increase  the local magnetic field. Gold nanoparticles based  on gold nanoparticles can be classified into three categories: optical  nano-biosensors, electrochemical nanofluorescents, and piezoelectric nano-biosensors  Also, metal nanoparticles such as pallet and silver are very popular due to their unique size  and electronic opto properties  Their size depends on the optical, magnetic, chemical and electrical  properties
