Adsorption Mechanisms in Layer-by-Layer Films

Sculptured Layer-by-Layer Films

The precise assembly of nanostructured materials into two (2D) and three-dimensional (3D) periodic microscopic arrays is achieved by employing various assembling technologies such as microparticle self-organization, photolithography, holographic lithography, selective chemical etching, ink printing, laser-based polymerization, selective responsive grafting, and inversion of bilayers. Soft litho...

Functional Multilayer Organic Thin Films Fabricated by Layer- by-Layer Sequential Adsorption Technique

A novel layer-by-layer sequential adsorption technique based on electrostatic interaction is a powerful way to fabricate multilayer organic thin films. The advantages of this technique include control over the number of layers, the architecture of the multilayers, and their ease of fabrication. By controlling the conditions of the polyion dipping solutions, such as salt concentration, solution ...

DNA release dynamics from bioreducible layer-by-layer films.

DNA release dynamics from layer-by-layer (LbL) films is an important aspect to consider with regards to localized gene delivery systems. The rate of DNA release and the condensation state of DNA during release are of particular interest in the field of gene delivery. A hyperbranched poly(amido amine) (RHB) containing bioreducible disulfide bonds is used to form interpolyelectrolyte complexes wi...

Layer-by-layer epitaxial thin films of the pyrochlore Tb2Ti2O7.

Layer-by-layer epitaxial growth of the pyrochlore magnet Tb2Ti2O7 on the isostructural substrate Y2Ti2O7 results in high-quality single crystal films of up to 60 nm thickness. Substrate-induced strain is shown to act as a strong and controlled perturbation to the exotic magnetism of Tb2Ti2O7, opening up the general prospect of strain-engineering the diverse magnetic and electrical properties of...
