Abstract

Nucleic acid-templated reactions have attracted significant attention for nucleic acid sensing and imaging. The level of signal amplification obtained from templated reactions is a function of the template turnover, wherein the template acts as the catalyst. Herein, we report the application of a pyridinium linker that immolates upon photocatalytic reduction with a ruthenium complex to yield the fastest nucleic acid templated reaction reported to date. We show that the templated reaction turnover is limited by the duplex dissociation kinetics beyond probes longer than a 6-mer and proceeded fastest for a 5-mer PNA probe. Using a beacon architecture that masks the catalytic template, we show that this methodology can be used for nucleic acid sensing extending the analyte recognition beyond a 5-mer. The system proceeds with a catalytic efficiency of 10 5 M –1 s –1 and achieves turnover frequency of >100 h –1 .

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Templated reactions (ligation or transfer reactions) are possible at much lower concentration, provided the hybridization yields sufficiently long-lived hybridization complex relative to the reaction rate.

    “Conversely, templated reactions (ligation or transfer reactions) have been shown to be possible at much lower concentration, provided the hybridization yields sufficiently long-lived hybridization complex relative to the reaction rate.22”
  • The primers used contain chiral PNA residues that hybridize exclusively to d-DNA.

    “However, the primers that were used contain chiral PNA residues22,41 that hybridize exclusively to d-DNA.42,43”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
