Electrochemical nanoarchitectonics through polyaminobenzylamine–dodecyl phosphate complexes: redox activity and mesoscopic organization in self-assembled nanofilms

Self-organization of mesoscopic silver wires by electrochemical deposition

Long, straight mesoscale silver wires have been fabricated from AgNO3 electrolyte via electrodeposition without the help of templates, additives, and surfactants. Although the wire growth speed is very fast due to growth under non-equilibrium conditions, the wire morphology is regular and uniform in diameter. Structural studies reveal that the wires are single-crystalline, with the [112] direct...

Crossbar nanoarchitectonics of the crosslinked self-assembled monolayer

A bottom-up approach was devised to build a crossbar device using the crosslinked SAM of the 5,5'-bis (mercaptomethyl)-2,2'-bipyridine-Ni(2+) (BPD- Ni(2+)) on a gold surface. To avoid metal diffusion through the organic film, the author used (i) nanoscale bottom electrodes to reduce the probability of defects on the bottom electrodes and (ii) molecular crosslinked technology to avoid metal diff...

DNA nanoarchitectonics: assembled DNA at interfaces.

DNA is a powerful biomaterial for creating rationally designed and functionally enhanced nanostructures. DNA nanoarchitectures positioned at substrate interfaces can offer unique advantages leading to improved surface properties relevant to biosensing, nanotechnology, materials science, and cell biology. This Perspective highlights the benefits and challenges of using assembled DNA as a nanosca...

Electrochemical Studies of Redox Properties and Diffusion in Self-Assembled Systems

Self-assembled virus-membrane complexes.

Anionic polyelectrolytes and cationic lipid membranes can self-assemble into lamellar structures ranging from alternating layers of membranes and polyelectrolytes to 'missing layer' superlattice structures. We show that these structural differences can be understood in terms of the surface-charge-density mismatch between the polyelectrolyte and membrane components by examining complexes between...
