1 Polyelemental Nanoparticle Libraries
NSF-MRSEC DMR M. Hersam, V. Dravid, C. Mirkin, Northwestern University MRSEC Multimetallic nanoparticles are useful in many fields (such as catalysis, electronics, optics, and magnetism), yet there are no effective strategies for synthesizing libraries of such structures with systematic compositional tunability. Mirkin used scanning probe block copolymer lithography (SBPCL, a technique invented in the Mirkin group) to synthesize multimetallic nanoparticles with independently controllable size and composition, incorporating up to five metals. SBPCL relies on the deposition of a polymer nanoreactor loaded with metal ion precursors, which are subsequently aggregated and reduced into multimetallic nanoparticles. This project leveraged collaborations with Hersam (IRG 3) and Dravid (IRG 2).
