Bending of Layer-by-Layer Films Driven by an External Magnetic Field
(Mdpi Ag, 2013-07-01)
We report on optimized architectures containing layer-by-layer (LbL) films of natural rubber latex (NRL), carboxymethyl-chitosan (CMC) and magnetite (Fe3O4) nanoparticles (MNPs) deposited on flexible substrates, which could ...
Amperometric glucose biosensor based on layer-by-layer films of microperoxidase-11 and liposome-encapsulated glucose oxidase
(Elsevier B.V., 2014-04-01)
An important step in several bioanalytical applications is the immobilization of biomolecules. Accordingly, this procedure must be carefully chosen to preserve their biological structure and fully explore their properties. ...
Renewable nanocomposite layer-by-layer assembled catalytic interfaces for biosensing applications
(2010)
A novel, easily renewable nanocomposite interface based on layer-by-layer (LbL) assembled cationic/anionic layers of carbon nanotubes customized with biopolymers is reported. A simple approach is proposed to fabricate a ...
Immobilization of liposomes in nanostructured layer-by-layer films containing dendrimers
(ELSEVIER SCIENCE BV, 2008)
Artificial vesicles or liposomes composed of lipid bilayers have been widely exploited as building blocks for artificial membranes, in attempts to mimic membrane interaction with drugs and proteins and to investigate drug ...
Structure and ferro/piezoelectric properties of SrBi(4)Ti(4)O(15) films deposited on TiO(2) buffer layer
(Elsevier B.V. Sa, 2009-05-27)
TiO(2) buffer layer was introduced between SrBi(4)Ti(4)O(15) (SBTi) thin films and Pt bottom electrodes through the soft chemical solution. The obtained films were characterized by X-ray diffraction, atomic force microscopy ...

The Bulk Band Structure and Inner Potential of Layered In4Se3
(Elsevier Science, 2008-12)
The layered In4Se3 system does have a bulk band structure (i.e. discernable and significant band dispersion) perpendicular to the cleavage plane. Band widths (the extent of dispersion) of 300 meV or more are observed, for ...
Molecular Ordering in Layer-by-Layer Polyelectrolyte Films Studied by Sum-Frequency Vibrational Spectroscopy: The Effects of Drying Procedures
(AMER SCIENTIFIC PUBLISHERS, 2008)
Sum-Frequency Vibrational Spectroscopy (SFVS) has been used to investigate the effect of nitrogen-flow drying on the molecular ordering of Layer-by-Layer (LbL) films of poly(allylamine hydrochloride) (PAH) alternated with ...
Layer-by-layer films containing SiO2 nanoparticles as field-effect pH sensors
(American Scientific Publishers - ASPValencia, 2013-02)
Devices for pH monitoring based on separative structures and high input impedance readout circuit were fabricated using silicon dioxide nanoparticles (SiO2-Np). SiO2-Np were self-assembled onto gold substrates via ...
Monoamine oxidase B layer-by-layer film fabrication and characterization toward dopamine detection
(Elsevier B. V., 2016-01-01)
In this work nanostructured film composites of the monoamine oxidase B (MAO-B) enzyme, free or encapsulated in liposomes, were fabricated by the layer-by-layer (LbL) self-assembly technique, employing polyethylene imine ...
