Bioinformatics is the application of computer technology for the management of biological information. Biological and genetic information can be gathered, stored, analyzed and integrated by computers for further gene-based drug discovery and development. This scientific field is essential for understanding human diseases and identifying new molecular targets for drug discovery by using genomic information. Biosensors are analytical devices which can be used for the detection of an analyte by combining a biological component with a physicochemical detector. Generally, the main purpose of a biosensor is to quickly test a sample for the presence of a target analyte. Biomolecules are generally used as the recognition component for the biosensor.
