A REVIEW ON RECENT ADVANCEMENT IN PORTABLE BIOSENSOR FOR HEALTH MONITORING

The use of biosensors and devices as instruments for health, education, and prevention has garnered a lot of attention in recent years. Personalized therapy depends on accurate and timely monitoring of biological markers and drug effectiveness, which is made feasible by biosensing devices in medications. The creation of the first real biosensor for oxygen sensing touches on the idea of biosensors. The “Web of Science” database had over 84,000 articles regarding “biosensors” between 2005 and 2015. Today, the field of research connects the foundations of electronics, micro/nanotechnology, applied medicine, and the basic sciences (physics, chemistry, and biology). The three primary components of a biosensor a bioreceptor, a transducer, and a signal processing system as well as the principles behind the various biosensor types are the main topics of the review. Additionally, the paper outlines several instances of biosensors being utilized to treat a range of illnesses, including infectious infections, diabetes mellitus, cardiovascular disease, and Alzheimer’s disease. Biosensors have several uses, many of which are intended to improve people’s quality of life. Applications in drug research, defence, food safety, illness detection, environmental monitoring, and many other fields are included in this spectrum. Additionally, biosensors can serve as platforms for tracking the nutritional content, safety, quality, and traceability of food.
