Binding of Perfluoroalkyl Substances to Nanoplastic Protein Corona Is pH-Dependent and Attenuates Their Bioavailability and Toxicity.
Article in Small science, 2024. 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
There is a severe lack of understanding of the effects of micro/nanoplastics on human proteins and cells, especially in the presence of organic pollutants. Herein, both in vivo and in vitro assays are conducted to structurally evaluate blood protein complexed with perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) as well as their coronas formed on polystyrene nanoplastics (PNs). PFOS is bound to serum albumin (SA) about 4 times as firmly as PFOA, which is not influenced by protein corona formation onto PN surfaces. However, the small molecular binding dramatically suppresses SA-PN aggregation. Low pH weakens the protein interaction of PFOS while not PFOA, which is also independent of PN adsorption, but the interaction with SA is still stronger for PFOS than PFOA, indicating higher serum persistence and risks. The presence of PN suppresses the cellular uptake of the chemicals and attenuates cytotoxicity due to low bioavailability. Overall, these results provide fundamental information on the ternary interaction mode of protein, particle, and organic pollutants in physiological environments with varying pH, as well as the subsequent cellular responses.
