Figure 7From: Biofabrication of Anisotropic Gold Nanotriangles Using Extract of Endophytic Aspergillus clavatus as a Dual Functional Reductant and StabilizerAFM images of gold nanotriangles synthesized by the reduction of 1 mM HAuCl 4 by endophytic A. clavatus after 48 h (a–b) and 72 h (c–d). Vertical stacking and clustering was observed with advancement of reaction period (a, c) within nanoparticles. Surface roughness of the nanoparticles was measured 25–30 nm (b, d).Back to article page
