MURI: Electrochemically-Controlled Orthogonal Assembly of Monolayers on a Gold Surface via DPN

摘要

Nature utilizes molecular recognition between complex macromolecules to form sophisticated meso- and macroscopic architectures with tremendous control over the placement and orientation of nanoscopic building blocks within the extended architectures. The structures of proteins, duplex DNA, and phospholipid bilayers are maintained by cumulative weak and reversible interactions (hydrogen bonding and van der Waals interactions), and pairing principles for the constituent molecules. The biosyntheses are remarkably efficient, self-correcting, and high yielding; therefore, they are excellent models for how the synthetic chemist should consider designing complex nanostructured materials. The specific objective of the proposed research was to demonstrate orthogonal assembly of charged particles by electrochemically controlling particle deposition. In addition, the use of applied potentials to selectively miniaturize microscopic features to nanoscopic dimensions was explored.
