Excited-State Relaxation and Förster Resonance Energy Transfer in an Organic Fluorophore/Silver Nanocluster Dyad.
Article in ACS omega, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A single-stranded DNA-based (ssDNA) dyad was constructed comprising 15 silver atoms stabilized by a ssDNA scaffold (DNA-AgNC) and an Alexa 546 fluorophore bound to the 5' end. The Alexa 546 was chosen to function as a Förster resonance energy transfer (FRET) donor for the AgNC. Time-correlated single photon counting (TCSPC) experiments allowed unraveling the excited-state relaxation processes of the purified DNA-AgNC-only system. The TCSPC results revealed slow relaxation dynamics and a red shift of the emission spectrum during the excited-state lifetime. The results from the model systems were needed to understand the more complicated decay pathways present in the collected high-performance liquid chromatography fraction, which contained the dyad (37% of the emissive population). In the dyad system, the FRET efficiency between donor and acceptor was determined to be 94% using TCSPC, yielding a center-to-center distance of 4.6 nm. To date, only limited structural information on DNA-AgNCs is available and the use of TCSPC and FRET can provide information on the center-to-center distance between chromophores and provide positional information in nanostructures composed of AgNCs.
