Abstract

Here, we explore the enhancement of single molecule emission by polymeric nano-antenna that can harvest energy from thousands of donor dyes to a single acceptor. In this nano-antenna, the cationic dyes are brought together in very close proximity using bulky counterions, thus enabling ultrafast diffusion of excitation energy (≤30 fs) with minimal losses. Our 60-nm nanoparticles containing >10,000 rhodamine-based donor dyes can efficiently transfer energy to 1-2 acceptors resulting in an antenna effect of ~1,000. Therefore, single Cy5-based acceptors become 25-fold brighter than quantum dots QD655. This unprecedented amplification of the acceptor dye emission enables observation of single molecules at illumination powers (1-10 mW cm-2) that are >10,000-fold lower than typically required in single-molecule measurements. Finally, using a basic setup, which includes a 20X air objective and a sCMOS camera, we could detect single Cy5 molecules by simply shining divergent light on the sample at powers equivalent to sunlight.

  • Such structures exhibit a giant light-harvesting behavior due to the efficient ultrafast excitation energy transfer (EET, <30 fs), enabling the detection of a single particle with ambient light.

    “In addition, such structures exhibit a giant light-harvesting behavior due to the efficient ultrafast excitation energy transfer (EET, <30 fs), enabling the detection of a single particle with ambient light (Figure 8b).154”

    From The Pursuit of Shortwave Infrared-Emitting Nanoparticles with Bright Fluorescence through Molecular Design and Excited-State Engineering of Molecular Aggregates (2022) · cites this paper as [154]

    The Abstract and Discussion report giant light harvesting driven in part by EET on a ≤30 fs timescale. They describe detection of single Cy5 molecules using the nanoantenna under sunlight-equivalent illumination, rather than establishing the claim as phrased about detecting a single particle with ambient light. The Methods section on microscopy specifies that the illumination was an artificial white light source mimicking sunlight. (LLM, conf=0.84)

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.
