Synthesis of Gold Nanoparticles Using Red Algae Extract

Ayman E. El-Sharkawey

A method for preparing gold metal nanoparticles, e.g., nanospheres and nanoprisms, includes combining an extract of red algae with chloroauric acid (HAuCl₄). The red algae can be Laurencia papillosa. The extract can include a water solvent extract. The chloroauric acid (HAuCl₄) can be in an aqueous solution. The method can include providing chloroauric acid (HAuCl₄), providing red algae extract, and combining the chloroauric acid (HAuCl₄) and the red algae extract to produce gold nanoparticles.
