Fig. 2From: Lipid-coated ZnO nanoparticles synthesis, characterization and cytotoxicity studies in cancer cellThe characterization of ZnO NPs structure (a–c). The HRTEM images of Pristine ZnO NPs (~ 7 nm; ~ 18 nm; ~ 49 nm). The inserted photos show the Fourier filtered image from the red box. d The SAED pattern shows a wurtzite pattern from sample ZnO NPs (~ 7 nm). e The EDX spectrum results from sample ZnO NPs (~ 7 nm), and f Lipid-coated ZnO NPs (~ 13 nm)Back to article page
