Manufacture of gold nanoparticles

04/10: An ecological method is developed to manufacture gold nanoparticles

Using a class of unusual liquids known as ionic solvents, researchers at the Korea Advanced Institute of Science and Technology, located in Daejeon, have developed a simple and non-polluting method to produce pure metal nanoparticles for biomedical applications. This new method has been published in the Journal of Materials Chemistry.

Dr. Huen Lee led the team in their effort to develop an aqueous phase synthesis of gold nanoparticles using ionic liquids derived from alcohols. Lee and his colleagues saw the possibility of using ionic liquids to obtain metal nanoparticles because of the ability of these types of fluids to both stabilize and facilitate the transfer of electrons to metal ions. This transfer of electrons is essential for the formation of metal nanoparticles from metal ions dissolved in a solvent.
