Fig. 4From: Facile Synthesis of Monodisperse Gold Nanocrystals Using Virola oleifera TEM images of AuNPs used to determine the monodispersity (a–d) with the aspect ratio (AR) value inset. The scale bars represent a 200 nm and b–d 100 nm. HR-SEM images of the AuNPs (e, f), and the scale bars represent 200 nmBack to article page
