Aptamers and Aptamer-Coupled Biosensors to Detect Water-Borne Pathogens

open access: yesFrontiers in Microbiology, 2021
Aptamers can serve as efficient bioreceptors for the development of biosensing detection platforms. Aptamers are short DNA or RNA oligonucleotides that fold into specific structures, which enable them to selectively bind to target analytes.

Aptamers based sensing of pregnancy associated glycoproteins (PAG) of bovine for early pregnancy detection

open access: yesScientific Reports, 2021
Tosyl activated magnetic beads were used for aptamer selection against PAG- 7 and 18 proteins of bovine origin. PAG proteins were immobilized on beads with further addition of biotin tagged aptamer library.

Aptamers as Therapeutics [PDF]

open access: yesAnnual Review of Pharmacology and Toxicology, 2017
Aptamers are single-stranded nucleic acid molecules that bind to and inhibit proteins and are commonly produced by systematic evolution of ligands by exponential enrichment (SELEX). Aptamers undergo extensive pharmacological revision, which alters affinity, specificity, and therapeutic half-life, tailoring each drug for a specific clinical need.

Methods for Improving Aptamer Binding Affinity

open access: yesMolecules, 2016
Aptamers are single stranded oligonucleotides that bind a wide range of biological targets. Although aptamers can be isolated from pools of random sequence oligonucleotides using affinity-based selection, aptamers with high affinities are not always ...

Aptamers and Their Biological Applications [PDF]

open access: yesSensors, 2012
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 stability, low cost, and unlimited applications. In this review, we present the reasons why aptamers are known as alternatives to antibodies.
