Figure 7: Characterization of AuNPs formed with 1 mM HAuCl4.3H2O and 5% GGLE at 40°C by high resolution transmission electron microscopy (HRTEM). (a) Small spherical AuNPs; (b) Spherical and triangular; (c) Gold nanohexagon equilateral edges; (d) Gold nanotriangles; (e) Scanning transmission mode micrographs for gold nanotriangle; (f) Elemental mapping of gold nanotriangle.
