Self-Aligned Multilayered Nitrogen Vacancy Diamond Nanoparticles for High Spatial Resolution Magnetometry of Microelectronic Currents.
Article in Nano letters, 2025. 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
Nitrogen vacancy diamond nanoparticles (NVNPs) are increasingly integrated with methods for optical detection of magnetic resonance (ODMR), providing new opportunities spanning the visualization of magnetic fields in microelectronic circuits, environmental sensing, and biology. However, only a small number of studies utilize aggregates of NVNPs for surface-wide magnetometry, with the fact that spin orientations in aggregate NVNPs are inherently misaligned, precluding proper magnetic field detection, compared with expensive monocrystalline diamonds. A post-processing method for layering NVNPs with aligned center orientations can potentially facilitate superior NV magnetometry by allowing sensitive detection with a simplified probe preparation. We present novel technology for creating densely stacked NVNP monolayers with inherent interlayer alignment for sensitive measurement of local field perturbations in microelectronic traces. We establish spatial characteristics of deposited aggregates and demonstrate their ability to capture dipoles from conducting microwires via ODMR. Our approach forms a novel accessible protocol that can be used for broad applications in micromagnetometry.
