The characterization of samples. a–c The TEM images and size distribution of pristine ZnO NPs (~ 7 nm; ~ 18 nm; ~ 49 nm). d–f Lipid-coated ZnO NPs (~ 13 nm; ~ 22 nm; ~ 52 nm), these samples were subjected to the negative staining techniques. In panels (a–f) the inserted figures show the size distribution of samples from the TEM images, n = 100 or 50
