Fabrication of Neu-LPs. A–C DLS measurements of Neu-LP size (A), zeta potential (B), and polydispersity index (C) (n = 3). D Representative TEM image of Neu-LPs stained with uranyl acetate. Scale bars, 50 nm. E Confocal fluorescence microscopy images and co-localization analysis of Neu-LPs (top) and a physical mixture of LPs and NMVs (bottom). Green, NMVs; red, LPs; scale bars, 500 nm. Statistical analysis was performed using Student’s t-test. Data are presented as mean ± SD
