Fig. 3From: Nanotechnological engineering of extracellular vesicles for the development of actively targeted hybrid nanodevicesCharacterization of TNH nanoconstructs. Representative a BF-TEM micrograph of TNHs negatively stained with uranyl acetate (scale bar: 20 nm); b ADF-STEM micrograph and c–f related EDS elemental maps (Scale bars: 200 nm) of Carbon (C), Oxygen (O), Phosphorous (P) and Zinc (Zn) elements; g EDS spectrum. Nanoparticle Tracking Analysis measurements of h ZnO NCs, i EVs, j TNHs before and k TNHs after the centrifugation step. Samples were analysed in 1:1 (v/v) of 0.1 μm-filtered bd water and physiological solutionBack to article page
