HR-TEM images of gold nanostars. The scale bars represent a 200 nm, b 50 nm, and c 5 nm. d A schematic representation of nanostars with an average size of 99.0 ± 47.0 nm. Image a was obtained without chitosan capping, and b and c were obtained with chitosan capping. The distance between neighboring lattices was measured to be 0.24 nm. Red arrows indicate the chitosan layer after capping
