Our group has been studying the preparation of stable, colloidally dispersed, gold, bismuth, and copper nanoparticles using a variety of reducing agents, polymeric ligands and metallic salt starting materials. My presentation will focus on the details pertaining to our present work on the preparation and characterization of copper nanoparticles. The metallic salts involved include copper(II) sulfate, copper(II) acetate, and copper(II)gluconate. Expanding on experimental data from gold nanoparticle research, the reducing agents/ligands have included SURFONAMINE(R) L-100 (a polyethermonoamine), porcine gelatin, polyphenolics, hydroquinone and aminoacids such as lysine. Polymeric ligands have included poly(ethylene glycol),poly(vinyl alcohol), poly(vinyl pyridine), and poly(vinyl pyrrolidone) run in solutions of either water or propylene carbonate. Comparison with these experimental results with those of gold nanoparticles has shown both similar and varying effects of color observation and reduction potential. With UV measurements and further spectroscopic testings, we hope to obtain results similar to those of gold nanoparticles.
