Optical label-free detection of SARS-CoV-2: investigating platform spectroscopic properties for oligonucleotide targeting.
Article in European biophysics journal : EBJ, 2026. 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
We characterized a DNA/gold interface designed for the detection of the SARS-CoV-2 RNA-dependent RNA polymerase/Helicase (RdRp/Hel) sequence. Using broadband spectroscopic ellipsometry (SE) and a difference spectra approach, we monitored molecular modifications at the interface, from probe sequence deposition to the insertion of a molecular spacer and subsequent hybridization with the target. The UV region revealed the characteristic DNA absorption peak around 260 nm, while changes in δΔ in the NIR correlated with increased optical thickness following each deposition step. The optical response was analyzed as a function of target concentration, and the binding affinity curve, derived from δΔ values at 800 nm, was fitted using a first-order Langmuir model, yielding a dissociation constant K
