Heterogeneous Nanopore Arrays - Selective Modification of Nanopores Embedded in a Membrane.
Article in Advanced materials (Deerfield Beach, Fla.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Much effort in the field of nanopore research has been directed toward reproducing the efficient transport phenomena of biological ion channels. For synthetic nanopores to replicate channel function on the scale of a cellular membrane, it is necessary to consider the modes of crosstalk between channels as well as to develop approaches to prepare nanopore arrays consisting of pores with different transport properties, akin to a membrane in an axon. In this manuscript, first ion concentration polarization (ICP) is identified as the primary means of the crosstalk, and subsequently, the extent and degree of ICP is tuned via targeted chemical modification of the pore walls' functional groups. Next, two fabrication methods of a model two-nanopore array are presented in a silicon nitride membrane in which one nanopore contains a bipolar ionic junction and functions as an ionic diode, while the other one is a homogeneously charged ionic resistor. The targeted chemical modification of a thin gold layer at the opening of one pore in an array that leaves the other pore located a few tens of nm away, unmodified, is utilized. These results provide an important framework for designing abiotic ionic circuits that can mimic physiological multichannel ion transport and communication.
