Method for synthesizing noble metal nanoparticles using dead cancer cells

Abstract

A method for preparing noble metal nanoparticles from dead cancer cells includes reacting an aqueous metal ion solution with an aqueous solution including dead cultured cancer cells to obtain a nanoparticle mixture, and isolating the nanoparticles from the mixture. The noble metal nanoparticles can be synthesized by using the dead cultured cancer cells with the media solution thereof or by using dead cancer cells from which cell culture media has been removed. The aqueous metal ion solution can include silver nitrate (AgNO3) and the noble metal nanoparticles formed can be silver nanoparticles. The metal ion solution can include chloroauric acid (HAuCl4) and the noble metal nanoparticles formed can be gold nanoparticles. The dead cultured cancer cells can include TK6 lymphoblastoid cell lines.
