Inhibition Assay of Biomolecules based on Fluorescence Resonance Energy Transfer (FRET) between Quantum Dots and Gold Nanoparticles
Abstract
An inhibition assay method was developed based on the modulation in the FRET efficiency between quantum dots (QDs) and gold nanoparticles (AuNPs) in the presence of the molecules which inhibit the interactions between QD- and AuNP-conjugated biomolecules. For the functionalization, AuNPs were first stabilized by chemisorption of n-alkanethiols and then capped with the first generation polyamidoamine (G1 PAMAM) dendrimers. By employing a streptavidin-biotin couple as a model system, avidin was quantitatively analyzed as an inhibitor by sensing the change in photoluminescence (PL) quenching of SA-QDs by biotin-AuNPs. The detection limit for avidin was about 10 nM. It is anticipated that the PL quenching-based sensing system can be used for the quantitative analysis and high throughput screening of molecules which inhibit the specific biomolecular interactions.

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.
