ABSTRACT
Molecular recognition is central to biosensor technology. Receptors,
enzymes, antibodies, aptamers, molecular beacons, and nucleic
acids are mainly used as molecular recognition elements in
biosensor development (Chambers et al., 2008). Since 1990, nucleic acids, especially deoxyribonucleic acid (DNA) have been used as
biorecognition elements in biosensor technology. These biosensors
are named as DNA-based biosensors.
