Biosensors are an interdisciplinary combination of bioactive materials (enzymes, proteins, DNA, antibodies, antigens, biofilms, etc.) and physicochemical transducers. They are an advanced detection method essential for the development of biotechnology. And monitoring methods are also rapid, micro-analytical methods for the molecular level of matter. Various biosensors have the following common structures: one or several related bioactive materials (biofilms) and physical or chemical transducers (sensors) capable of converting biologically active signals into electrical signals, a combination of the two Together, modern microelectronics and automated instrumentation technology are used to reprocess biosignals to form a variety of biosensor analysis devices, instruments, and systems that can be used. Principle of biosensor The substance to be tested is diffused into the biologically active material, and after molecular recognition, a biological reaction occurs, and the generated information is then converted into a quantifiable and processable electrical signal by a corresponding physical or chemical transducer, and then amplified by a secondary instrument. And output, you can know the concentration of the analyte. Biosensor classification According to the classification of living substances used in the susceptor, it can be divided into: microbial sensors, immunosensors, tissue sensors, cell sensors, enzyme sensors, DNA sensors, and the like. According to the principle of sensor device detection, it can be divided into: thermal biosensor, FET biosensor, piezoelectric biosensor, optical biosensor, sonic biosensor, enzyme electrode biosensor, mediator biosensor, etc. According to the type of bio-sensitive substance interaction, it can be divided into affinity type and metabolism type.
