ABSTRACT Biosensors are analytical devices that integrate biological recognition elements with transducers to detect specific analytes, offering high sensitivity, selectivity, and real‐time monitoring capabilities. Biological sensors are playing a major and crucial role nowadays in many fields, whether it be medical diagnosis or monitoring the environment, drug discovery, forensics, and many more. The use of biosensors has made immense progress in the field of technology. In healthcare, biosensors are pivotal in detecting biomarkers for diseases, monitoring blood glucose, and managing chronic conditions. Food industries leverage biosensors for freshness evaluation and contamination detection, while biotechnology utilizes them for monitoring fermentation and cell culture processes. The continuous advancements in nanotechnology and microfabrication are further enhancing biosensor sensitivity and portability, driving their future potential in personalized medicine and point‐of‐care (PoC) diagnostics. Biosensors are also made from biological components and have become a game‐changer. This review paper explores biosensors, their components, and their use in various fields.
