Fig. 2From: Dual-labeled nanoparticles based on small extracellular vesicles for tumor detectionPhysicochemical characterization of dual-sEVs. A Radioactive (red) and UV/VIS (blue) HPLC chromatograms of dual-sEVs (normalized intensity), and UV/VIS HPLC chromatogram of non-labeled sEVs (green). B Radio TLC chromatogram (counts/mm × 1000) of dual-sEVs. C Fluorimetric analysis (relative fluorescent units; RFU) of the maximum emission peak of dual-sEVsBack to article page
