Fibronectin/polyelectrolyte multilayered assemblies: film formation and cell attachment studies

Biomimetic materials capable of specific interactions with a biological environment represent the current biomaterial paradigm within tissue engineering and drug delivery [1]. Electrostatically driven layer-by-layer (LbL) self-assembly [2,3] is a simple and robust method for realizing structurally tailored biomaterial coatings, of thickness ca. 10 nanometers, containing biofunctional ligands. W...

Porphyrin Diacid-Polyelectrolyte Assemblies: Effective Photocatalysts in Solution

Developing effective and versatile photocatalytic systems is of great potential in solar energy conversion. Here we investigate the formation of supramolecular catalysts by electrostatic self-assembly in aqueous solution: Combining positively charged porphyrins with negatively charged polyelectrolytes leads to nanoscale assemblies where, next to electrostatic interactions, π–π interactions also...

Counterion structure and dynamics in polyelectrolyte solutions

Investigations of the counterion distribution and correlations to polyelectrolytes have seen increased activity to understand intrinsically stiff and flexible polyelectrolytes in good solvents as functions of ionic strength, charge valence, and concentration. In particular, anomalous (resonant) small-angle X-ray scattering and small-angle neutron scattering have provided new insights on counter...
