Nanoporous Graphene Integrated onto Bimodal Waveguide Biosensors for Detection of C-Reactive Protein.
Article in ACS applied nano materials, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Despite the outstanding progress in photonic sensor devices, a major limitation for its application as label-free biosensors for biomedical analysis lies in the surface biofunctionalization step, that is, the reliable immobilization of the biorecognition element onto the sensor surface. Here, we report the integration of bottom-up synthesized nanoporous graphene onto bimodal waveguide interferometric biosensors as an atomically precise biofunctionalization scaffold. This combination leverages the high sensitivity of bimodal waveguide interferometers and the large functional surface area of nanoporous graphene to create highly sensitive, selective, and robust biosensors for the direct immunoassay detection of C-reactive protein (CRP), an inflammatory biomarker widely used in the clinical diagnosis of infections and sepsis. The limit of detection was determined at 3 ng/mL, which is well below the clinical cutoff levels required for the diagnostic detection of CRP in patient samples. This innovative approach holds promise for transforming diagnostics, environmental monitoring, and various fields requiring precise biomolecular detection.
