Gold-Alloy Nanoparticles

Gold-alloy nanoparticles are fabricated by pulsed-laser ablation like the gold nanoparticles, except that the laser target is mixture of gold and a non-gold metal. These gold-alloy nanoparticles can be tuned for plasmonic and magnetic properties depending upon the non-gold metal and ratio of gold to non-gold metal.
