Sampling Sub-Diffraction Temperature Gradients with Spectrally Orthogonal Nanoparticle Luminescence.
Article in ACS photonics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Recording the temperature-dependent luminescence emitted by an isolated single nanoparticle offers one strategy for performing far-field optical thermometry with spatial resolution below the diffraction limit. However, such measurements are inherently restricted to probing the temperature at a single spatial point. Here, we demonstrate an approach to sampling temperature gradients at multiple points within a subdiffraction region by simultaneously collecting the emission from different nanoparticle species with spectrally orthogonal temperature-dependent luminescence. Taking advantage of the narrow spectral bands and wavelength tunability of lanthanide-doped upconverting nanoparticle (UCNP) emission, we use a single laser to excite both NaYF
