Superparamagnetic Biomembranes for Dynamic Nanoparticle and Molecular Patterning.
Article in Nano letters, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
We introduce superparamagnetic biomembranes as a novel, actively tunable hybrid platform. The superparamagnetic biomembranes are supported lipid bilayers (SLBs) with defined lipid composition and site-specific coupling of proteins and superparamagnetic nanoparticles (MNPs). Application of magnetic field gradients induces rapid and fully reversible lateral transport of lipid-anchored MNPs with forces in the femtonewton range. Using single magnetic tips as well as multiple magnetic tips and line structures, we achieve parallelized and spatially defined MNP patterning. Transition of the SLB from the liquid-crystalline phase to the gel phase enables reversible immobilization of the patterned MNP distributions. Local MNP accumulation displaces lipids and membrane-associated proteins, including Neutravidin, mEGFP, and CD19, thereby generating inverse molecular gradients that are recognized by living cells. This biocompatible substrate with dynamically controllable nanoparticle and molecular organization provides a versatile framework for applications in bio- and nanotechnology.
