DNA Testing Using an Enzyme Based Amperometric Biosensor with Nano Composites and Its Instrumentation

Abstract

BIOSENSOR is an instrument in biomedical engineering which plays a key role in instrumentation systems and transducers. The instruments are divided into type in which they are used for a specific purpose. Example: LVDT, THERMO COUPLE are mechanical parametric measuring instruments. Voltmeters and ammeters are used in electrical measuring parameters. Biosensors are used in medical field with biological elements as transducers. Biological elements are ANTIBODIES, DNA, RNA, ENZYME, MICRO FLUIDICS. Transducers are electrical or electronic type which convert biological signal into measurable electrical signal.DNA is basic building block of human body which is sequenced and is used for cancer detection using biosensor.
