Figure 1: TEM micrograph of PtNP synthesis via laser ablation. The histograms show the size distribution of the synthesised nanoparticles. a) Formation of PtNPs in 0.01 M SDS aqueous solution and b) PtNPs produced in pure water. c) and d) display the measured length of PtNPs from a) and b) respectively.
