Bio-informatics
Bio-informatics is an interdisciplinary field which addresses biological problems using computations techniques and makes the rapid organization and analysis of biological data possible. The field may also be referred to as computational biology and can be defined as—
“Conceptualizing biology in terms of molecules and then applying informatics technique to understand and organize the information associated with these molecules on a large scale.”
Bio-informatics plays a key role in various areas such as functional genomics, structural genomcs and proteomics and forms a key component in the biotechnology and pharmaceutical sector.
Biosensor
A biosensor is an analytical gadget comprising of an immobilized layer of a biological material (Example: enzyme, antibody, hormone) inconjunction with a transducer which analyses the biological signals and converts them into an electrical signal.
Example: BOD sensor, Nitrate sensor, Ammonia sensor, sulfide ion sensor.
Bio-sensor works on the following principle
A layer of suitable biological material is immobilized on a permeable membrane which is kept in the close vicinity of a sensor. The substance to be measured passes through the membrane and interact with the immobilized material and yield a product. The product passes through another membrane to the transducer. The transducer converts into an clectrical signal which is amplified and displayed or recorder.
