| Abstract: | DNA is a satisfactory construction of new devices for nanotechnology and biosensors.DNA biosensors have been developed in recent years due to their high sensitivity and good selectivity.It has been found that a range of nanomaterials such as metal nanoparticles(MNPs)and carbon-based nanomaterials,have been introduced in the sensor design to enhance the sensing performance of electrochemical DNA sensor.In this review,we introduced and discussed recent progresses in the design and fabrication of efficient electrochemical genosensors based on carbon nanostructures such as field effect transistor,graphene and carbon nanotubes. |
