Aptamer-Modified Micellar Electrokinetic Chromatography for the Enantioseparation of Nucleotides

Analytical Chemistry, 2009
In this paper, a new aptamer-based capillary electrophoresis (CE) method, which was able to separate the enantiomers of an anionic target (adenosine monophosphate, AMP) displaying the same electrophoretic mobility as that of the oligonucleotidic chiral selector, is reported.

Artificial Nucleotide Aptamer-Based Field-Effect Transistor for Ultrasensitive Detection of Hepatoma Exosomes

Analytical Chemistry, 2022
An aptamer-based field-effect transistor (Apta-FET) is a well-developed assay method with high selectivity and sensitivity. Due to the limited information density that natural nucleotide library holds, the Apta-FET faces fundamental restriction in universality to detect various types of analytes.

Signaling Aptamers Created Using Fluorescent Nucleotide Analogues

Analytical Chemistry, 2006
A new approach to creating fluorescent signaling aptamers using fluorescent nucleotide analogues is presented. The fluorescence quantum yield of nucleotide analogues such as 2-aminopurine strongly depends on base stacking interactions when incorporated into double or single stranded DNA. This property is used to generate a binding-specific fluorescence
