Biosynthesis of gold nanoparticles using,,,, extract

biosynthesis of gold nanoparticles using dried flowers extract of . Achillea wilhelmsii . as the reducing agent. Rapid reduction of gold ions was observed leading to the formation of gold nanoparticles in solution. The formation of gold nanoparticles was confirmed by the presence of an absorption peak at 580 nm using UV–visible spectrophotometry.
