TEM images of: (a) AuNSp5, (b) AuNSp10, (c) AuNSp20, (d) AuNR808, (e) AuNR980, (f) AuNR6 dispersed in (left) water, (right) PBS solution what imitates the human skin conditions. Noticeably, nanoparticles exhibit a strong tendency to agglomerate and adhere to the PBS particles, which is considered to reflect the similarity of the human skin – gold nanoparticles interaction.
