Upgradation in biosensor: An emerging paradigm for advanced biomedical application

With the advent of the development of biosensor devices, scientists are more focused on emerging new biosensor technologies and tools. The existing application of these devices in fields of biomedicine, drug discovery, food safety, and environmental monitoring get remarkable importance. Till today diagnostic tests especially for early detection and monitoring of cancer and anticancer chemotherapeutic agents bearing major challenges despite their simplicity. This review aims to highlight the use of biosensors as diagnostic means along with their future applicability. In the past various achievement in the development of biosensors opened a new gateway for researchers to further modify biosensing elements to enhance their detection ability particularly in cancer that requires continued development and validation of biomarkers and development of ligands for those biomarkers, as well as continued development of sample preparation methods and multichannel biosensors able to analyze many cancer markers simultaneously. The future for biosensor is promising and bright however require a determined, cost-effective and multi-disciplinary approach to bring out biosensor system from research and development laboratory to market place.
