LED-Modulated Plasmoporation for Highly Efficient Intracellular Cargo Delivery to Suspension Cells.
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
Intracellular delivery of bioactive cargoes remains a major bottleneck in engineering therapeutic cellular responses. Here we report LED-modulated plasmoporation driven by the plasmonic photothermal effect of large-area gold nanoislands (AuNIs) for highly efficient cargo delivery into suspension cells. Plasmoporation operates through a sequential microfluidic network with AuNIs and a white LED module. LED-modulated mild photothermal cycling induces transient membrane phase transition and poration, followed by thermal relaxation for membrane recovery. Precisely controlled LED modulation shows intracellular delivery of propidium iodide into Jurkat cells with 80% delivery efficiency and 93% cell viability. Arrhenius-model-based analysis of LED-modulated temperature pulse-trains identifies an optimal cumulative cellular thermal damage (Ω) range of 0.11-0.15, yielding ≥70% delivery efficiency while maintaining high cell viability. Plasmoporation further demonstrates intracellular delivery of macromolecules up to 2000 kDa with delivery efficiencies exceeding 50%. This low-power, scalable plasmoporation offers a new approach for high-throughput immune cell engineering and therapeutic intracellular delivery.
