Reversible supramolecular modification of surfaces

Enzymes are biocatalysts widely used in a large number of industrial biotech processes as they offer clear advantages over their chemical counterparts. Indeed, enzymes often show high substrate selectivity along with elevated turnover rates. Enzymatic cata ...

Exploiting Dispersion-driven Aggregators as a Route to New One-dimensional Organic Nanowires

Riccardo Petraglia, Adrien Georges Nicolai, Hongguang Liu

The efficiency of charge carrier mobility in organic semiconductors is heavily dependent upon the long-range organization (i.e., morphology) and the local relative arrangement of the transporting molecules. Here, we exploit London dispersion forces as a de ...

Local Conformational Switching of Supramolecular Networks at the Solid/Liquid Interface

Klaus Kern, Magalí Alejandra Lingenfelder, Fernando Pablo Cometto

We use the electric field in a scanning tunneling microscope to manipulate the transition between open and close packed 2D supramolecular networks of neutral molecules in nonpolar media. We found that while the magnitude of the applied field is not decisiv ...

Supramolecular assemblies of organotin(IV)-diphosphoryl adducts: insights from X-rays and DFT

Kurt Schenk

Mono-, di- and tri-phenyltin(IV) adducts containing a neutral diphosphoryl ligand, Ph2P(O)OC6H4OP(O) Ph-2, were synthesized and characterized. These 2 : 1 adducts of two trans-organotin(IV) moieties and the bridging ligand all crystallize around a centre o ...

Infinite geometric frustration in a cubic dipole cluster

Tobias Schneider

The geometric arrangement of interacting (magnetic) dipoles is a question of fundamental importance in physics, chemistry, and engineering. Motivated by recent progress concerning the self-assembly of magnetic structures, the equilibrium orientation of eig ...

Molecularly Engineered Self-Assembling Membranes for Cell-Mediated Degradation

Jeffrey Alan Hubbell, Daniela Sofia Dias Ferreira, Yi-An Lin

The use of peptide engineering to develop self-assembling membranes that are responsive to cellular enzyme activities is reported. The membranes are obtained by combining hyaluronan (HA) and a rationally designed peptide amphiphile (PA) containing a proteo ...

Contact angle and adsorption energies of nanoparticles at the air-liquid interface determined by neutron reflectivity and molecular dynamics

Francesco Stellacci, Javier Reguera Gomez, Mauro Moglianetti, Evgeniy Ponomarev

Understanding how nanomaterials interact with interfaces is essential to control their self-assembly as well as their optical, electronic, and catalytic properties. We present here an experimental approach based on neutron reflectivity (NR) that allows the ...

Isolation and Characterization of Monodisperse Core Shell Nanoparticle Fractions

Francesco Stellacci, Randy Patrick Carney, Raffaele Mezzenga

Monodispersity is a key property to control the self-assembly of colloidal particles, and is typically reached after fine-tuning of the synthesis conditions. Monodisperse particle fractions can also be separated from polydisperse suspensions via ultracentr ...

A Study of Yield Predictions for a Model of Homogeneous Self-Assembling Components

Massimo Mastrangeli

Self-assembly of homogeneous components has the advantage of being a decentralised and highly parallel method for assembling multiple target structures, and is ideal for effective large-scale manufacturing. Yet assembly yield may be negatively affected by ...

Merging microfluidics and micro-array concepts: from molecular to nematode-based bioassays

Matteo Cornaglia

Essential in biomedical research is the necessity of gathering statistically relevant data about large populations of specific biological entities, e.g. organisms, cells or molecules, while preserving detailed information about each single entity under in ...
