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 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 …

We presented a new aptamer biosensor for thrombin in this work, which was based on
fluorescence resonance energy transfer (FRET) from upconverting phosphors (UCPs) to …

A novel bioassay strategy is designed to detect small‐molecule targets such as cocaine,
potassium, and adenosine, based on gold nanoparticles (AuNPs) and engineered DNA …

In this review we examine various methods for the immobilization of aptamers onto different
substrates that can be utilized in a diverse array of analytical formats. In most cases …

In this study, an electrochemical aptamer based sensor (aptasensor) was proposed for
