Abstract : DNA, protein, and peptide strategies, together with chemical synthetic techniques, are exploited to create nanoparticle (NP) arrays for systematic study of quantum many-body physics in structures fabricated by biological techniques. Periodic arrays where quantum many-body physics occur within each NP and interparticle coupling of charge, electric dipole, or magnetic dipole occurs among particles are considered. The primary focus is placed on studies of magnetic interactions. Magnetic NP with organic shells suitable for functionalized attachment at specific sites on the scaffolding were assembled into arrays by DNA-directed self-assembly and drop-casting. The DNA scaffolding was suitable for controlling the coupling between the NP by DNA base sequence design and by NP shell composition and thickness, to allow future systematic studies of interactions within the arrays. The convergent goal of this interdisciplinary project was defined to be the use of DNA scaffolding for the assembly of ferromagnetic NP arrays closely coupled to an electron gas near the surface of a semiconductor for the study of many-body physics in electrically gated magnetic NP arrays. It is anticipated that this MURI will contribute to a fundamental understanding of electronic and magnetic behavior in nanoparticle arrays, which could impact computing, signal processing, and sensing.
