Molecularly Engineered Fluorescent Magnetic Microrobots for Sensing High-Energy Nitroaromatic Explosives in Highly Acidic Aqueous Environments.
Article in Small (Weinheim an der Bergstrasse, Germany), 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
Among various analytical sensing approaches currently in use, fluorescence sensing is known for its high sensitivity, rapid response, and applicability in monitoring a wide range of target molecules. Pairing an appropriate navigation system with a fluorescent molecule that can carry it to inaccessible or hard-to-reach environments can pave the way for remote and selective sensing applications. Herein, we design magnetic nanoparticles embedded with fluorescent material to form magneto-fluorescent, precisely navigable microrobots for sensing high-energy explosive compounds in acidic aqueous systems. Magnetic guidance via Helmholtz coils provides dynamic navigational control to direct the microrobots to specific regions of interest using externally applied magnetic fields. Upon specific interaction with picric acid, the sensing mechanism is triggered via fluorescence quenching ("on-off" switch). Materials characterization demonstrates that this quenching mechanism arises from the hydrogen bonding and charge-transfer interactions between ketenimine-functionalized probes and the hydroxyl group in picric acid, leading to the formation of water-soluble picrate complexes. Testing in microfluidic channels as proof-of-concept further validates the microrobot's ability for selective sensing of target analytes, emphasizing them as smart mobile sensors for environmental monitoring in harsh acidic conditions, confined spaces, hazardous material detection, and applications in the real world where conventional sensors face challenges.
