Microfluidic-Integrated Chip Resonators for Electron Spin Sensing in Submicromolar, Submicroliter Solutions.

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
Planar or chip microresonators decrease the sample volume required for magnetic resonance spectroscopies to the nanoliter scale. However, the interrogation of nanoliter-scale solution samples on planar sensors is hindered by the lack of microfluidic devices that can simultaneously provide a small total volume and long-term sample stability. Here, we report microfluidic devices that decrease the total required sample volume to the submicroliter scale and also provide long-term physical stability and storability. We also report a 3D-printed microfluidic with a self-contained actuation mechanism, which allows the sample to be retracted from the microresonator surface for storage. The microfluidic devices are fabricated easily by laser cutting or 3D printing and are integrable with a broad range of planar sensors. We use planar inverse anapole (PIA) microresonators to obtain continuous wave (CW) electron paramagnetic resonance (EPR) spectra of natural-isotopic-abundance nitroxide radicals, which are ubiquitously used as reporters of biomolecular dynamics. We provide experimental evidence for a concentration sensitivity of 330 ± 40 nmol L
