Time-dependent ex situ TEM images revealed some intermediate nanostructures during the Pep-1 induced formation of Au nanostars. A) TEM image showing Au nanocrystals formed at 15 min. B) HRTEM demonstrating the single-crystaline characteristics of small particles. C) TEM image of Au particles formed at 24 h, showing the formation of some spherical five-fold twinned nanocrystals. D) TEM image of Au nanocrystals formed at 36 h, showing the emergence of Au star. E) HRTEM image showing the five-fold twinned nanocrystals surrouded by small single crystalline particles. F) TEM image of Au nanocrystals formed at 48 h, showing the five-fold twinned star dominant structure. G), H) HRTEM image showing the exsitence of non-conventional or irregular five-fold twinned particles.
