ABSTRACT
The combination of nanomaterials and biomolecules has led to a
new generation of DNA sensing devices. Taking advantage of the
size-dependent properties of nanomaterials and the unique inter-
facial phenomenon that result in their coupling with electrochem-
ical transducers, many different biosensing strategies have been
realized. The use of nanoparticles, various nanowires, nanotubes,
nanorods, etc. have all been incorporated into novel DNA sensing
schemes. Thus, the field of biotechnology has recently witnessed
extensive progress in the use of nanomaterial-based electrochemical
DNA sensors.
