Metallic alloy nanoparticles are synthesized by combining two or more different metals. Bimetallic or trimetallic nanoparticles are considered more effective than monometallic nanoparticles because of their synergistic characteristics. In this review, we outline the structure, synthesis method, properties, and biological applications of metallic alloy nanoparticles based on their plasmonic, catalytic, and magnetic characteristics.
Keywords: alloy nanoparticles; bimetallic nanoparticles; biological application; photocatalytic property; super-magnetism; synergistic effect; trimetallic nanoparticles.
