The term biosensor stands for the biological sensor. This sensor device is made up of a transducer and the biological elements. Usually, this consists of the biological elements such as an antibody, an enzyme, and a nucleic acid. To point out, the biological elements is the root cause to practice any biosensor technology. Also, these technologies are applicable in the several industries as the real-time application. To mention, these applications play a vital role nowadays while in comparison with the many latest trending inventions.
Usually, this is a simple process, and it gives many benefits in several industries. This is the process of interaction and testing. The interactions between the bio-element and analyte, and then the testing process occurs. Usually, the testing occurs after the completion of interaction, and it tests whether the biological response converts into an electrical signal with the transducer. This is to detect the analyte and henceforth, it is called an analytical device. To mention, this device gathers the biological components with the physicochemical which is a detector that detects the analyte.
Usually, the biosensor is of two following categories.
In this biosensor type, the antibody and the transducer of an acoustic wave is coupled. The membrane’s mass varies when the analyte molecule gets attached with the membrane. This results in the change of the resonant frequency on the transducer, and it is measured.
The output that is the frequency change of the resonant biosensor can also be the reason of the optical biosensor that is based on the optical diffraction and electrochemiluminescence. Particularly, this is an attractive application that is to detect the bacteria with this sensor, and it is also possible to detect the minute changes in the thickness or refractive index of the surface of the transducer. Additionally, several optical technique reports to detect the pathogens of the bacteria which includes dielectric waveguides, surface Plasmon resonance and so on. There are several subfields of the optical biosensor that may include the following:
The fields that use biosensor technology are:
Specifically, the glucose monitor is the well-known example for the clinically applied biosensors. The glucose monitor used routinely by every diabetic’s individuals to analyze their level of blood sugar. Through this device, it is possible to blood glucose amount in undiluted blood samples permitting for the dynamic self-testing and monitoring that has modernized diabetes management. Hence, it is much helpful in the medical industry for the detection purpose.
In the food industry, biosensors are useful to measure alcohols, acids, and carbohydrates. For instance, it is a quality control process. Additionally, this devices helpful for the fermentation check in the production of beer, yoghurt, and soft drinks. Another crucial application is, it can detect pathogens in the fresh meat, poultry or fish.
Biosensors use to check the quality of air and water. The devices use to pick up traces of organophosphates from the pesticides or to check the toxicity levels of wastewater.
In those days, there are no devices to detect any hazards in their field. But in recent days, with the help of biosensor technology, it is easy for farmers to detect if there are any hazards in their farm field.
As a result, these biosensor technology has its applications in several industries, and this facilitates to the human beings and diminishes the human resources.
