Selective Activation of Dynamics in Kinetically Frozen Supramolecular Polymer Bottlebrush Assemblies.
Article in Small (Weinheim an der Bergstrasse, Germany), 2025. 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
Supramolecular assemblies are typically characterized by their dynamic nature due to the comparable weak non-covalent interactions. While these properties confer adaptability, stability issues may limit application in areas such as drug delivery or tissue engineering. Here, supramolecular assemblies of amphiphilic polymers containing benzenetrispeptide and benzenetrisureas motifs are inherently stable and non-dynamic at ambient conditions is shown, but dynamic exchange can be selectively activated. Stimulated emission depletion microscopy combined with automated image analysis revealed no dynamic exchange between complementary labeled fibers independent of the length of the hydrophobic domains at ambient conditions in pure water for several days. Competitive solvent addition facilitates dynamic exchange but compromises stability. Raising the temperature of the samples in pure water to 60 °C, however, induces similar dynamics while fiber stability is maintained. The amphiphilic character, in combination with the strong hydrogen bonds, seems to endow these supramolecular polymer brushes with unique switchable dynamics.
