  • SYNTHESIS OF GOLD NANOPARTICLES USING RED ALGAE EXTRACT
    Publication number: 20170298474
    Abstract: 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 a red algae extract, and combining the chloroauric acid (HAuCl4) and the red algae extract to produce gold nanoparticles.
