Controlled fabrication of gold nanoparticles biomediated by glucose oxidase immobilized on chitosan layer-by-layer films
(ELSEVIER SCIENCE BV, 2009)
The control of size and shape of metallic nanoparticles is a fundamental goal in nanochemistry, and crucial for applications exploiting nanoscale properties of materials. We present here an approach to the synthesis of ...
A long-term controlled drug-delivery with anionic beta cyclodextrin complex in layer-by-layer coating for percutaneous implants devices
(2021-04-01)
This study demonstrated a drug-delivery system with anionic beta cyclodextrin (β-CD) complexes to retain tetracycline (TC) and control its release from multilayers of poly(acrylic acid) (PAA) and poly(l-lysine) (PLL) in a ...
Implementation of diverse non-centrosymmetric layer concepts for tuning the interface activity of a magnesium alloy
(2016-01-01)
Magnesium and its alloys are the lightest metallic materials used for structural applications. Tuning the surface functionalization of magnesium alloys may contribute to increasing their durability. Dry or wet processes ...
Enzyme activity of horseradish peroxidase immobilized in chitosan matrices in alternated layers
(ELSEVIER SCIENCE BV, 2009)
The successful immobilization of enzymes such as horseradish peroxidase (HRP) in solid films is essential for applications in sensors and for fundamental studies aimed at identifying possible biotechnological devices. In ...
Long-Term Stability at High Temperatures for Birefringence in PAZO/PAH Layer-by-Layer Films
(AMER CHEMICAL SOCWASHINGTON, 2012)
Optical memories with long-term stability at high temperatures have long been pursued in azopolymers with photoinduced birefringence. In this study, we show that the residual birefringence in layer-by-layer (LbL) films ...
Electrooptic proprieties of layer-by-layer films of a azobenzene containing copolymer
(2005-12-01)
The methacrylic copolymer functionalized with the azo chromophore 4-[N-ethyl-N-(2-hydroxiethyl)]-amino-2′-chloro-4-nitroazobenzene (MMADR13), in its polyelectrolyte form, can be used to fabricate thin films by the ...

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 ...
