DNA Based Biosensors

Abstract

Biosensors especially DNA biosensors find use in diverse fields like clinical, food adulteration prevention, and in the monitoring of the environment. The DNA based biosensors have gained prominence in detection and monitoring and are the ultimate choice due to their high sensitivity and selectivity. Novel synthetic probes have been exploited for their use in various clinical settings. Here in this review, the major DNA biosensor technologies available in the market is discussed with the addition of two crucial technological breakthrough in detecting mercury poisoning as well as DNA damage due to ultraviolet light is also discussed. DNA biosensors technology is evolving at a faster pace and is coming up with the rational solution in the detection of various clinical conditions as well as coverage area like environmental pollution, which we can now detect at a faster rate with the help of state of the art DNA biosensors in no time. Thus DNA biosensors are becoming part and parcel of the mainstream science, and through this review, a try has been made to address the various issues relating to DNA biosensors in today’s world
