Photochromic layer-by-layer films of spiroxazine polymer
Dyes and Pigments, 2007Abstract Photochromic films of cationic spiroxazine polymer ( SOP ) were assembled via the electrostatic layer-by-layer (LBL) method, in which SOP layers were alternated with the polyanionic polystyrenesulfonate ( PSS ). The multilayer formation was monitored via UV–vis spectroscopy by measuring the increase in absorbance at 610 nm.

Electropolymerization of layer‐by‐layer precursor polymer films
Polymers for Advanced Technologies, 2011AbstractThe layer‐by‐layer (LbL) self‐assembly has been used to fabricate polymer thin films on any solid substrates. The multilayer polymer thin films are constructed by alternating adsorption of anionic and cationic polymers. Polyelectrolyte multilayer ultrathin films containing anionic poly[2‐(thiophen‐3‐yl)ethyl methacrylate‐co‐methacrylic acid]; P(

Layer-By-Layer Film Engineering for Sequential Gene Delivery
2019Layer-by-layer (LbL) films are assembled with poly(amido amine)s (PAAs), a type of polycations containing bioreducible disulfide bond, and DNA plasmids to enable LbL film degradation in physiologic conditions by reacting with glutathione or redox-active membrane proteins.

Layer-by-Layer Thin Films of Carbon Nanotubes
MRS Proceedings, 2005AbstractLayer-by-layer films incorporating single-wall carbon nanotubes (SWNTs) with anionic or cationic coatings have been prepared. The process of self-assembly was monitored using the quartz microbalance technique, while the morphology of the resulting thin layers was studied with atomic force microscopy.

Surface Imprinting in Layer‐by‐Layer Nanostructured Films
Advanced Functional Materials, 2007AbstractIn this Full Paper, we develop a novel approach for the generation of stable molecularly imprinted sites in polymeric films by combining the layer‐by‐layer (LbL) technique and photochemical crosslinking of the layered structure. After photo‐crosslinking, the imprinted films show high reproducibility and rapid loading and unloading of imprinted ...

Multilevel and Multicomponent Layer-by-Layer Assembly for the Fabrication of Nanofibrillar Films
ACS Nano, 2015In this study, we demonstrate multilevel and multicomponent layer-by-layer (LbL) assembly as a convenient and generally applicable method for the fabrication of nanofibrillar films by exploiting the dynamic nature of polymeric complexes. The alternate deposition of poly(allylamine hydrochloride)-methyl red (PAH-MR) complexes with poly(acrylic acid ...

Protein-Triggered Instant Disassembly of Biomimetic Layer-by-Layer Films
Langmuir, 2011Layer-by-Layer (LbL) coatings are promising tools for the biofunctionalization of biomaterials, as they allow stress-free immobilization of proteins. Here, we explore the possibility to immobilize phosvitin, a highly phosphorylated protein viewed as a model of bone phosphoproteins and, as such, a potential promotive agent of surface-directed ...

Layer-by-Layer Assembled Films of Cellulose Nanowires with Antireflective Properties
Langmuir, 2007Natural nanowires (NWs) of cellulose obtained from a marine animal tunicate display surprisingly high uniformity and aspect ratio comparable with synthetic NWs. Their layer-by-layer assembled (LBL) films show strong antireflection (AR) properties having an origin in a novel highly porous architecture reminiscent of a "flattened matchsticks pile", with ...
