Advances and application of common biosensors

Abstract

Biosensors are devices that can detect and measure chemical components in organisms through specialized biological properties or reactions. This paper provides an overview of the three main types of biosensors: enzymatic, immunosensors, and microbial sensors. Enzymatic biosensors utilize enzymes to catalyze specific reactions between target molecules and other components of the biosensor, creating measurable signals. Immunosensors rely on immunological reactions between antigens and antibodies to detect and quantify substances in a solution. Microbial sensors use microbial cells to produce signal outputs being tested. Each type of biosensor has unique applications and mechanisms that make them useful in various scientific studies, including clinical medicine, laboratory research, environmental monitoring, and food engineering. Ongoing advancements in technology will undoubtedly continue to expand the scope of biosensors uses, making them increasingly important in many fields. This paper aims to provide researchers with an understanding of the mechanisms behind biosensors and strategies to improve their performance for better measurement, detection, and monitoring capabilities.
