Assembly-Controlled Biocompatible Interface on a Microchip: Strategy to Highly Efficient Proteolysis

A biocompatible interface was constructed on a microchip by using the layer-by-layer (LBL) assembly of charged polysaccharides incorporating proteases for highly efficient proteolysis. The controlled assembly of natural polyelectrolytes and the enzyme-adso ...

Photoproduction of proton gradients with pi-stacked fluorophore scaffolds in lipid bilayers

Natalie Renuka Banerji, Stefan Matile, Eric Vauthey

Rigid p-octiphenyl rods were used to create helical tetrameric p-stacks of blue, red-fluorescent naphthalene diimides that can span lipid bilayer membranes. In lipid vesicles containing quinone as electron acceptors and surrounded by ethylenediaminetetraac ...

Benefiting from the Unique Properties of Lanthanide Ions

The recent upsurge of interest in contrast agents for magnetic resonance imaging, of luminescent chemosensors for medical diagnostic, and lately, for optical imaging of cells has generated an impressive momentum for the coordination and supramolecular chem ...

Realistic modeling of nanostructures using density functional theory

Nicola Marzari

The development of materials and devices at the nanoscale presents great challenges, from synthesis to assembly to characterization. Often, progress can only be made by complementing work with electronic-structure modeling, harnessing the efficiency, predi ...

MEMS-based nanopatterning: new challenges and opportunities for Materials Science

Jürgen Brugger

Micro-mechanical systems are exquisite tools for high-resolution surface patterning. As an alternative to traditional photolithography, they can be used for local material deposition at the sub-100 nm scale. This can be either done by means of liquid dispe ...

Coexistence of one- and two-dimensional supramolecular assemblies of terephthalic acid on Pd(111) due to self-limiting deprotonation

Klaus Kern, Harald Brune, Marta Canas Ventura, Sylvain Clair

The adsorption of terephthalic acid [C6H4(COOH)(2), TPA] on a Pd(111) surface has been investigated by means of scanning tunneling microscopy (STM), x-ray photoelectron spectroscopy, and near-edge x-ray absorption fine structure spectroscopy under ultrahig ...

Autonomous Self-assembly in Swarm-Bots

Francesco Mondada, Michael Bonani, Roderich Gross

In this paper, we discuss the self-assembling capabilities of the swarm-bot, a distributed robotics concept that lies at the intersection between collective and self-reconfigurable robotics. A swarm-bot comprises autonomous mobile robots called s-bots. S-b ...

Directed assembling of gold nanoparticles using Van der Waals interactions

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

In the last past years, many promising applications of nanoparticles in quantum electronics such as nanocrystal memories, chemical sensors or nanodevices based on single electron tunneling and Coulomb blockade effects have attracted much attention. Nanopar ...

Nonlinear optics of molecular nanostructures in solution: Assessment of the size and nonlinear optical properties

Dmitri Ivanov

Most of the known self-assembly processes occur in solution, where nanosized objects interact each other forming new structures. Their real-time characterization in terms of the size and optical properties of these objects is vital for understanding those ...

Lipid membranes for the fabrication of functional micro- and nano-structures

Gopakumar Gopalakrishnan

The central goal of this thesis work is to fabricate novel, functional fluorescent nanostructures in confined systems offered by phospholipid membranes, which are known to have highly ordered, thermotropic and lyotropic structures. In separate approaches, ...
