Caracterização por espectroscopia vibracional de filmes Layer-by-Layer contendo ftalocianina, polímeros condutores e gomas naturais
(Universidade Estadual Paulista (UNESP), 2014)
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 ...

Spray layer-by-layer films based on phospholipid vesicles aiming sensing application via e-tongue system
(Elsevier B.V., 2012-05-01)
The Layer-by-Layer (LbL) technique via spraying (spray-LbL) has been applied as new and alternative methodology to fabricate ultrathin films due to its versatility in relation to the conventional dipping-LbL method, mainly ...
Layer-by-layer composite film of nickel phthalocyanine and montmorillonite clay for synergistic effect on electrochemical detection of dopamine
(Elsevier B.V., 2018-04-01)
Dopamine (DA) abnormal levels are related to diseases which makes important the development of fast, reliable, low-cost and sensitive devices for diagnosis and pharmaceutical controls. Nanostructured film composite of ...
Nanocompósitos eletroativos de poli-o-metoxianilina e polissacarídeos naturais
(Sociedade Brasileira de Química, 2007-10-01)
In this work we take advantage of the polyelectrolyte character of some Brazilian native gums to fabricate electrically conductive, nanostructured films. The gums Sterculia urens, (caraia), Sterculia striata (chicha) or ...
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 ...
Immunosensors made with layer-by-layer films on chitosan/gold nanoparticle matrices to detect d-dimer as biomarker for venous thromboembolism
(2018-01-01)
We report on immunosensors to detect D-dimer, a biomarker of venous thromboembolism, which are made with layer-bylayer (LbL) films containing immobilized anti-D-dimer monoclonal antibody alternated with a layer of chitosan/gold ...
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 ...
Caracterização por espectroscopia vibracional de filmes Layer-by-Layer contendo ftalocianina, polímeros condutores e gomas naturais
(Universidade Estadual Paulista (Unesp), 2009-06-19)
Esta dissertação apresenta o estudo do crescimento (em escala nanométrica) e morfológica (em escala micrométrica) de filmes finos fabricados segundo a técnica Layer-by-Layer (LbL) contendo ftalocianina tetrasulfonada de ...
