Biosensors For Secondary Metabolites

Now-a-days, Biosensors are witnessed to be a booming interest in both research and commercial fields. DNA biosensors are otherwise called as Genosensors. DNA biosensors can be theoretically used in medical diagnostics and forensic science. The advantage in using these devices is no external monitoring is required. The usage of these bio sensors is rapidly increased in genetic screening and detection. In comparison to other methods of assays, DNA biosensors obtain promisingly the better and specific information in human, viral and bacterial Nucleic acid in a very faster, simpler and cheaper manner. The biosensor consists of a biological sensing element attached to the signal transducer. The sensing elements can be DNA, Antibodies, enzymes and the transducer may be optical or electrochemical. Transducers are the major component of a biosensor which measures the change in the fluorescence, absorbance and frequency of the elements. The covalent attachment involves the chemical attachment to the support molecules. It is important to be noted that the word “immobilization” can refer to a short-term, long-term or “permanent” localization of the biomolecule as it involve the pair of molecules with strong affinity interactions.
