Carbon nanotube enhanced label-free detection of microRNAs based on hairpin probe triggered solid-phase rolling-circle amplification.

A Label-Free and Sensitive Fluorescent Qualitative Assay for Bisphenol A Based on Rolling Circle Amplification/Exonuclease III-Combined Cascade Amplification

Bisphenol A (BPA) detection in drinking water and food packaging materials has attracted much attention since the discovery that BPA can interfere with normal physiological processes and cause adverse health effects. Here, we constructed a label-free aptamer fluorescent assay for selective and sensitive detection of BPA based on the rolling circle amplification (RCA)/Exonuclease III (Exo III)-c...

A cascade signal amplification strategy for sensitive and label-free DNA detection based on Exo III-catalyzed recycling coupled with rolling circle amplification.

A sensitive and label-free fluorescence assay for DNA detection has been developed based on cascade signal amplification combining exonuclease III (Exo III)-catalyzed recycling with rolling circle amplification. In this assay, probe DNA hybridized with template DNA was coupled onto magnetic nanoparticles to prepare a magnetic bead-probe (MNB-probe)-template complex. The complex could hybridize ...

A novel label-free cascade amplification strategy based dumbbell probe-mediated rolling circle amplification-responsive G-quadruplex formation for highly sensitive and selective detection of NAD

Sensitive detection of microRNA by chronocoulometry and rolling circle amplification on a gold electrode.

We developed a quantitative detection scheme for nucleic acids, combining solid-phase rolling circle amplification and chronocoulometry (RCA-CC). A gold electrode was directly formed on a polystyrene substrate as a cost-effective and flexible biosensor for sensitive detection of microRNA (mir-143) in blood samples.

Rolling Circle Amplification (RCA): an approach for quick detection and identification of fungal species

Conventional methods for fungal identification in the clinical laboratory rely on morphological andphysiological tests. These tests often need several days or weeks to complete and are frequentlyunspecific. Molecular identification mostly implies sequencing, which is relatively expensive andtime-consuming, as well as impractical for large numbers of isolates. The Rolling CircleAmplification app...
