📖 Recently, Deoxyribonucleic Acid (DNA) has become an interesting candidate for conduction of electrical current. The outcome could be useful in nanotechnology and nanoelectronics for the design of electrical circuits, which could in turn help to overcome the limitations that classical silicon (Si)-based electronics would be facing in coming years.The utilization of DNA in electronic device such as micro and nano sensors in recent years has increased. High throughput micro array sensors in biotechnology applications and medical diagnosis, MEMS and NEMS opens up new windows for utilization of DNA based sensors.
