A biosensor is an integrated bioanalytical device that employs biological elements, as analyte sensor, coupled to a transducer for signal detection. Biosensor provides sensitive and selective determination of various compounds of analytical relevance. Recently, use of self-assembled monolayer (SAM) is gaining attention as biosensor matrix. SAM provides a simple route to functionalize electrode surfaces for biosensor fabrication. The alarming rise in the rates of heart diseases due to abnormal levels of cholesterol in blood has stimulated public concern about the estimation of cholesterol...

Nucleic acid biosensors have been found to have interesting possibilities for applications in various fields including environmental and medical screening. The two types of analysis used for the nucleic acid biosensors are: (a) detection of genotoxicants/ DNA damage (b) detection of DNA hybridization. For the detection of genotoxicants, the double stranded calf thymus DNA has been electrochemically entrapped into conducting polymers like Polypyrrole (PPy) and Polyaniline (PANI) films to detect chlorpyrifos and malathion. Compared to DNA-PPy, DNA-PANI electrodes have better detection limit for...
