Abstract

The extract of Clidemia hirta fruit has been selected as a reaction partner with chloroauric compounds in reactions that produce gold nanoparticles. Extract Clidemia hirta fruit was obtained in a simple way by heating the fruit in demineralized water at 70 C. The extract obtained was mixed with a solution containing gold ions at room temperature. The reaction proceeded quickly, as indicated by the extract^s rapid change in color when added to the gold ion solution drop by drop. According to the Transmission Electron Microscope (TEM) analysis, the particle size was between nanosize and microsize. The analysis results using the particle size analyzer (PSA) show that the current condition gives a particle size average of 121 nm.
