The electrochemical biosensors are a class of biosensors which convert biological
information such as analyte concentration that is a biological recognition element …

Serving as the basis of cell life, interactions between nucleic acids and proteins play
essential roles in fundamental cellular processes. Aptamers are unique single-stranded …

Recently, aptamers have attracted the attention of many scientists, because they not only
have all of the advantages of antibodies, but also have unique merits, such as thermal …

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 have attracted intense interest and found wide applications in a
range of areas. In this review, we summarize recent advances in the development of …

Aptamers are ligand-binding nucleic acids whose affinities and selectivities can rival those
of antibodies. They have been adapted to analytical applications not only as alternatives to …

Nucleic acid aptamers are promising alternatives to antibodies in analytics. They are
generally obtained through an iterative SELEX protocol that enriches a population of …

The selection of aptamers—nucleic acids that specifically bind low‐molecular‐weight
substrates or proteins—by the SELEX (systematic evolution of ligands by exponential …

Aptamers are artificial nucleic acid ligands, specifically generated against certain targets,
such as amino acids, drugs, proteins or other molecules. In nature they exist as a nucleic …
