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 …

This article reviews recent achievements in developing aptamer‐based electrochemical
biosensors (electrochemical aptasensors). Aptamers are single stranded DNA or RNA …

Protein nanopores have been used as stochastic sensors for the detection of analytes that
range from small molecules to proteins. In this approach, individual analyte molecules …

Aptamers are artificial oligonucleotides (DNA or RNA) selected in vitro that bind a broad
range of targets with high affinity and specificity; a sensitive yet simple method to utilize …

Oligonucleotides were once considered only functional as molecules for the storage of
genetic information. However, the discovery of RNAzymes, and later, DNAzymes, unravelled …

Surface plasmon resonance (SPR) biosensors prepared using optical fibers can be used as
a cost-effective and relatively simple-to-implement alternative to well established biosensor …

An electrochemical aptasensor is a compact analytical device where the bioreceptor
(aptamer) is coupled to a transducer surface to convert a biological interaction into a …

Single-stranded DNA or RNA aptamer molecules have usually been selected against
purified target molecules. To eliminate the need of purifying target molecules on the cell …

Many biological processes (physiological or pathological) are relevant to membrane
proteins (MPs), which account for almost 30% of the total of human proteins. As such, MPs …

Aptamers are a promising class of agents for biomolecules detection due to their small size,
chemical stability and cost effectiveness over conventional bioreceptors such as antibodies …
