Highly Sensitive Colorimetric Detection of Ochratoxin A by a Label-Free Aptamer and Gold Nanoparticles
A label-free aptamer-based assay for the highly sensitive and specific detection of Ochratoxin A (OTA) was developed using a cationic polymer and gold nanoparticles (AuNPs). The OTA aptamer was used as a recognition element for the colorimetric detection of OTA based on the aggregation of AuNPs by the cationic polymer. By spectroscopic quantitative analysis, the colorimetric assay could detect ...
متن کاملDNA transducer-triggered signal switch for visual colorimetric bioanalysis
A simple and versatile colorimetric biosensor has been developed for sensitive and specific detection of a wide range of biomolecules, such as oligonucleotides and aptamer-recognized targets. Combining the signal transducer and catalyzed hairpin assembly (CHA)-based signal amplification, the target DNA binds with the hairpin DNA to form a new nucleic acid sequence and creates a toehold in the t...
متن کاملPVP-coated graphene oxide for selective determination of ochratoxin A via quenching fluorescence of free aptamer.
In this paper, we developed a simple method to detect fungi toxin (ochratoxin A) produced by Aspergillus Ochraceus and Penicillium verrucosumm, utilizing graphene oxide as quencher which can quench the fluorescence of FAM (carboxyfluorescein) attached to toxin-specific aptamer. By optimizing the experimental conditions, we obtained the detection limit of our sensing platform based on bare graph...
متن کاملFast colorimetric sensing of adenosine and cocaine based on a general sensor design involving aptamers and nanoparticles.
Aptamers are nucleic acid based binding molecules that are obtained through a combinatorial selection process known as systematic evolution of ligands by exponential enrichment (SELEX). 2] They are emerging as a new class of molecules that can rival antibodies in terms of the broad range of molecules they can selectively bind. In comparison with antibodies, aptamers, particularly DNA aptamers, ...
متن کاملA peroxidase-active aptazyme as an isothermally amplifiable label in an aptazyme-linked oligonucleotide assay for low-picomolar IgE detection.
A peroxidase-active hemin-aptamer was clicked onto an immunoglobulin E (IgE) binding aptamer. The resulting bifunctional aptamer was successfully used in a highly sensitive aptazyme-linked oligonucleotide assay (ALONA) for the detection of IgE. The sensitivity of the assay is enhanced by isothermal amplification of the aptazyme followed by colorimetric detection of the aptazyme's peroxidase act...
