On-off transition and ultrafast decay of amino acid luminescence driven by modulation of supramolecular packing.
Article in iScience, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Luminescence of biomolecules in the visible range of the spectrum has been experimentally observed upon aggregation, contrary to their monomeric state. However, the physical basis for this phenomenon is still elusive. Here, we systematically examine all coded amino acids to provide non-biased empirical insights. Several amino acids, including non-aromatic, show intense visible luminescence. Lysine crystals display the highest signal, whereas the very chemically similar non-coded ornithine does not, implying a role for molecular packing rather than the chemical characteristics. Furthermore, cysteine shows luminescence that is indeed crystal packing dependent as repeated rearrangements between two crystal structures result in a reversible on-off optical transition. In addition, ultrafast lifetime decay is experimentally validated, corroborating a recently raised hypothesis regarding the governing role of nπ∗ states in the emission formation. Collectively, our study supports that electronic interactions between non-fluorescent, non-absorbing molecules at the monomeric state may result in reversible optically active states by the formation of supramolecular fluorophores.
