1 · What the graph read from it

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.

2 · The registry

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

Nanopore-based single-molecule biosensors have been extensively studied. Protein pores that have receptors attached to them are target-selective, but their real-time applications are limited by the fragility of the lipid membrane into which the protein pores are embedded. Synthetic nanopores are more stable and provide flexible pore sizes, but the selectivity is low when detecting in the translocation mode. In spite of modifications with probing molecules, such as antibodies, to potentiate specific targeting, these nanopores fail to bind individual target molecules. Distinguishing between binding and translocation blocks remains unsolved. Here, we propose an aptamer-encoded nanopore that overcomes these challenges. Aptamers are well-known probing oligonucleotides that have high sensitivity and selectivity. In contrast to antibodies, aptamers are much smaller than their targets, rendering target blockades in the nanopore much more distinguishable. We used aptamer-encoded nanopores to detect single molecules of immunoglobulin E and the bioterrorist agent ricin, sequentially captured by the immobilized aptamer in the sensing zone of the pore. The functional nanopore also probed sequence-dependent aptamer-protein interactions. These findings will facilitate the development of a universal nanopore for multitarget detection.
