DNA is one of the most fascinating biopolymers. Besides its central role as carrier of genetic
information and translation of the genetic code into proteins, DNA holds great promise as a …

Sensors are devices that respond to physical or chemical stimuli and produce detectable
signals. 1r4 They are a critical extension of human perception of the world in many aspects …

Nucleic acid aptamers are single stranded DNA or RNA sequences that specifically bind a
cognate ligand. In addition to their widespread use as stand-alone affinity binding reagents …

Aptasensors are aptamer-based biosensors with excellent recognition capability towards a
wide range of targets. Specially, there have been ever-growing interests in the development …

In this critical review we review enzymatic systems which involve biocatalytic reactions
utilized for information processing (biocomputing). Extensive ongoing research in …

Mercury ion (Hg2+) is able to specifically bind to the thymine− thymine (T− T) base pair in a
DNA duplex, thus providing a rationale for DNA-based selective detection of Hg2+ with …

DNAzymes are single stranded DNA molecules that exhibit catalytic activity and are
exploited in medicine, biology and material sciences. Development in this area is related to …

Aptamers emerged over 20 years ago as a class of nucleic acids able to recognize specific
targets. Today, aptamer-related studies constitute a large and important field of …

Graphene oxide (GO) is implemented as a functional matrix for develo** fluorescent
sensors for the amplified multiplexed detection of DNA, aptamer–substrate complexes, and …

Aptamers are exciting smart molecular probes for specific recognition of disease biomarkers.
A number of strategies have been developed to convert target–aptamer binding into …
