A Microfluidic SERS Assay to Characterize the Phenotypic Heterogeneity in Cancer-Derived Small Extracellular Vesicles.
Article in Methods in molecular biology (Clifton, N.J.), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Small extracellular vesicles (sEVs) are nanoscopic bioparticles that transport biomolecular cargoes between cells. sEVs have been implicated in many pathological processes such as cancer, rendering them as promising targets for therapeutics and diagnostics. Characterizing phenotypic differences in sEV biomolecular cargos could support understanding their roles in cancer. However, this is difficult due to similar physical properties of sEVs and requirement for highly sensitive analysis. Our method describes the preparation and operation of a microfluidic immunoassay with surface-enhanced Raman scattering (SERS) readouts, termed sEV subpopulation characterization platform (ESCP). ESCP applies an alternating current induced electrohydrodynamic flow to enhance collisions of sEVs with the antibody-functionalized sensor surface. Captured sEVs are labeled with plasmonic nanoparticles to facilitate multiplexed and highly sensitive phenotypic characterization of sEVs by SERS. ESCP is demonstrated for characterizing the expression of three tetraspanins (CD9, CD63, CD81) and four cancer-associated biomarkers (MCSP, MCAM, ErbB3, LNGFR) in sEVs derived from cancer cell lines and plasma samples.
