Beyond superquenching: Hyper-efficient energy transfer from conjugated polymers to gold nanoparticles
Open accessAbstract
Gold nanoparticles quench the fluorescence of cationic polyfluorene with Stern–Volmer constants ( K SV ) approaching 10 11 M — 1 , several orders of magnitude larger than any previously reported conjugated polymer–quencher pair and 9–10 orders of magnitude larger than small molecule dye–quencher pairs. The dependence of K SV on ionic strength, charge and conjugation length of the polymer, and the dimensions (and thus optical properties) of the nanoparticles suggests that three factors account for this extraordinary efficiency: ( i ) amplification of the quenching via rapid internal energy or electron transfer, ( ii ) electrostatic interactions between the cationic polymer and anionic nanoparticles, and ( iii ) the ability of gold nanoparticles to quench via efficient energy transfer. As a result of this extraordinarily high K SV , quenching can be observed even at subpicomolar concentrations of nanoparticles, suggesting that the combination of conjugated polymers with these nanomaterials can potentially lead to improved sensitivity in optical biosensors.

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.
