Pep-1-induced formation of spherical coral-shaped gold nanoparticles. a, b TEM images with different magnifications showing monodispersed spherical coral-shaped nanoparticles (scale bar, 50 nm for a, 10 nm for b). c HR-TEM revealing that the coral-shaped particles are composed of distorted nanorods (scale bar, 5.0 nm). dg, Four high-resolution TEM images of distorted gold nanorods and clusters of nanorods formed in early stages of spherical coral-shaped particle formation, in which nanorods with (111) lattice fringes are presented (d) and clusters of nanorods exhibit both (111) and (200) fringes (eg) (scale bar, 5.0 nm). hm In situ liquid cell TEM time series (scale bar, 20 nm) showing the birth of gold NPs (h, i), nanorods (j), distorted nanorods (k), and the clusters of distorted nanorods (l, m) during early stages of coral-shaped particle formation; top right corner insets of h, i are the high-magnification TEM images showing the gold NPs (scale bar, 10 nm). n The proposed model showing Pep-1-induced spherical coral-shaped nanoparticle formation via the random attachment of distorted nanorods
