Fig. 3From: Lipid-coated ZnO nanoparticles synthesis, characterization and cytotoxicity studies in cancer cellThe HRTEM images of pristine ZnO NPs. a ZnO NPs (~ 7 nm); b ZnO NPs (~ 18 nm); c ZnO NPs (~ 49 nm). The ZnO NPs formed layer-by-layer either parallelly or perpendicularly to the C-axis. The arrows indicate the boundaries of the pristine particlesBack to article page
