Chirality-selective optical transport of nanoparticles in the evanescent field of a nanofibre.

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
Selective optical manipulation of nanoparticles according to their chirality is a challenge due to the relatively small size of the chirality-dependent optical force. Here, we introduce the evanescent field of optical nanofibres as a promising tool for such manipulation. Using circularly polarised fibre modes, we demonstrate strongly chirality-selective optical transport of a chiral nanoparticle. Our experiments, backed by simulations, show that right- and left-handed circularly polarised modes produce clearly distinct velocities of optically trapped chiral nanoparticles along the nanofibre. Furthermore, using a counterpropagating mode configuration, the non-chiral component of the optical force can be cancelled, yielding selective forward and backward transport. The chiral optical force was found to be significant even for particle ensembles with natural variations in size and form, implementing optical separation of chiral enantiomers at the scale of 100 nm. Further development towards waveguide-assisted enantioselective manipulation approaching the molecular scale can be envisaged.
