One-Shot SERRS Detection of Iron and Acidity in Aqueous Systems.
Article in ACS applied materials & interfaces, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Optical strategies for ion sensing hold promise for portable and in situ analysis, yet their reliability is frequently limited by pH-dependent interferences that alter metal-ligand interactions. Herein, we present a multiprobe surface-enhanced resonance Raman scattering (SERRS) platform that enables simultaneous quantification of Fe(II) and direct in situ pH readout in aqueous media. The sensor is constructed from polystyrene beads (PS) densely coated with silver nanoparticles and functionalized with two probes: phenanthroline (Phen), a metal-selective dye, hydrophobically entrapped within a cetrimonium bromide (CTAB) bilayer to retain its Fe(II) binding activity, and 4-mercaptobenzoic acid (MBA), covalently anchored to the silver surface to provide a reliable pH response. Resonant excitation at 532 nm maximizes SERRS sensitivity, yielding Fe(II) detection down to 30 ppb with strong selectivity against competing metal ions. Crucially, the MBA readout decouples pH effects from Fe(II) quantification, avoiding false results at alkaline pH where iron hydroxide precipitates dominate. This dual-sensing strategy provides a robust concept to overcome pH interference in optical ion sensing and paves the way for portable, time-resolved monitoring of metal ions in biological and environmental systems.
