Biosensors are rational or scientific devices that are generally used to convert any measurable and biochemical signal of a molecule or chemical entity into an analytical and useful, visual outcome based on physicochemical principle. A wide variety of stimulus are generally used by biosensors to transform qualitative or quantitative changes to identifiable or recognizable signals. They are of great benefit to society in current pandemic situations possessing huge potentials not only in the field of detection but also in diagnosis, prognosis and treatment. In contemporary times, diseases and infections have greatly increased taking a huge toll on health expenditure of individuals, overall quality of life and even mortality of persons at a time. Applications include early detection of disease, disease prognosis, biomolecule recognition, surveillance, monitoring, identification, etc. Besides, they also play a phenomenal role in pathogens or microbial identification and detection of various other lethal microbes in food, medication, various matrices and systems, diseased and infectious conditions and are being widely used nowadays. Many electronics as well as instrument manufacturers are currently investing in this burgeoning domain knowing that this health sector holds great promise and rewards. Massive progress and advancement have been witnessed in this scientific field in the past few years and expected to maintain this snowballing trend. Research and development (R & D) in modern micro-level and nanolevel sensor systems serves to associate multidimensions like biology, chemistry, nanoscience and physics, by the amalgamation of various fields such as nanomaterials, electrical circuits, chemicals, sensors, probes, etc. One of the most important areas of focus nowadays is the manufacture of specific, cost-effective and multiplexed or versatile bio-sensing devices that can be used in diverse fields of medicine and disease. This chapter explores the importance of the application of biosensors, their use, and current and future trends in the field of disease diagnosis, along with their advantages and disadvantages. |
