Introduction Immunosensor or commonly known as Biosensor came together by combining a biological receptors and a sensor to make one device. It is a device for the detection of an analyte. The analytical device which functions to analyze a sample for the presence of specific compound is the sensor and using a biological material to specifically interact with the analyte is known as biosensor. Biosensor involves converting a chemical flow of information into electric signal and is classified based on common types of bioreceptors. In general, the aim of biosensor is to enable quick convenient testing at the point of concern and care where the sample was procured. There are three components that made up a biosensor- bioreceptor, bio…show more content…
Disadvantaged is that the sensor’s lifetime is limited by the stability of the enzyme. iii. Nucleic acid interaction: Biosensor that optimizes this interaction may also be known as genosensors. The recognition is based on DNA’s complementary bases. Once, they are able to detect its targeted nucleic acid, the complementary base sequence can be synthesize, labeled and immobilized by the sensor. iv. Epigenetics v. Organelles: Different kind of organelles have different metabolic pathway and have enzymes to fulfill its function. e.g. Mitochondrion is used to detect the calcium concentration in medium. It also used for detection of water pollution. vi. Cells: Cells are commonly used as they are sensitive to surrounding and they can respond to all kinds of stimulants. They are more reactive as compared to organelles and are able to reproduce and make them reusable. It is commonly used to monitor the treatment of drugs and also used to detect global parameter like stress condition, toxicity and organic derivatives. vii. Tissue Tissues have abundance of enzymes available and hence it makes it easier to immobilize compared to cells or organelles. It has higher activity and stability from enzymes in natural environment. It is easily available and is inexpensive. Tissues are easier to use as there is no need to do tedious work such as extracting,
