This research was carried out to synthesize and functionalize amine to gold nanobipyramids it’s aims to increase the stability of the gold nanobipyramids properties. The gold nanobipyramids (GNBPs) have been successfully synthesized by seed mediated growth method. using growth solution which consists of 0.875 mL HAuCl4 0,01 M, 0.025 mL H2PtCl4 0,01 M, 20 mL CTAB 0,1 M, 0.2 mL AgNO3 0.01 …
