A biosensor is an analytical device that combines a physicochemical detector with a biological component for chemical substance detection. The sensitive biological element, such as cell receptors, enzymes, antibodies, nucleic acids, and so on, is a substance or biomimetic component that binds to, recognizes, or interacts with the analyse under investigation. Biology can also be used to make the parts that are sensitive to life. The transducer or the finder component, which changes one sign into another, works in a physicochemical way=electrochemical, electrochemiluminescence, optical, piezoelectric, etc., resulting from the analyses interaction with the biological component, making it simple to measure and quantify. The biosensor peruser gadget interfaces with the related hardware or sign processors that are fundamentally liable for the presentation of the outcomes in an easy to use way. This occasionally represents the most costly piece of the sensor gadget, but it is feasible to produce an easy to use show that incorporates transducer and delicate component (holographic sensor). In most cases, the readers are made and designed specifically to accommodate the various biosensor operating principles. The degree of integration of the various components in a biosensor can be divided into three generations. How the bio recognition or bio receptor molecule is attached to the base transducer element.


In the original, the bio receptor is genuinely entangled nearby the base sensor behind a segregating film like a dialysis layer. In resulting ages, immobilization is accomplished through covalent bonds at a reasonably changed transducer interface or by joining into a polymer framework at the transduction surface. The bio receptor molecule becomes an essential component of the base sensing element in the third generation, whereas the individual components remain essentially distinct in the second generation (for instance, control electronics-electrode- biomolecule). The analytical device that incorporates a biological sensing element is referred to as a “biosensor,” and it can be used for a wide range of purposes, including drug discovery, diagnosis, biomedicine, food safety and processing, environmental monitoring, defence, and security. The strategy of electrochemically detecting oxygen or hydrogen peroxide using an immobilized glucose oxidase electrode was used in the initial biosensor that Clark and Lyons developed in 1962 to measure glucose in biological samples.


Since then, innovative approaches ranging from electrochemistry to nanotechnology to bioelectronics have led to significant advancements in biosensor technology and application. This review aims to provide fundamental knowledge and present the scientific scenario of biosensor technology in light of the phenomenal advancements in the field of biosensors by introducing various technical strategies used in the development of biosensors. With a focus on the research tools that show how the performance of biosensors changed from electrochemical to optical/visual, polymers, glass, silica, and nanomaterial’s were used to increase the detection limit, sensitivity, and selectivity. Interestingly, bioluminescence and microbes also played a significant role in the development of label-based biosensors, whereas nanomaterials and devices based on transistors or capacitors were utilized in the development of label-free biosensors. For quantitative biologists, biosensors provide a foundation for comprehending technological advancement in instrumentation, which includes portable qualitative or semi-quantitative devices for non-specialists and sophisticated high-throughput machines for quantitative biologists. Finally, limitations in the field, challenges in the future, and current research trends are discussed. Even though these definitions were probably meant for enzyme electrode systems, biosensors in general can be categorized in a similar way. The bulk of these families’ development is now visible in the second and third generations [1-4].
