Flavin adenine dinucleotide functionalized gold nanoparticles for the electrochemical detection of dopamine
(2022-11-01)
Dopamine (DA) is a neurotransmitter with multiple functions in the central nervous system, and whether found in low levels, activation of biological defense system and physiological activity is influenced. DA at abnormal ...
Copper hexacyanoferrate nanoparticles modified electrodes: A versatile tool for biosensors
(ELSEVIER SCIENCE SA, 2008)
Copper hexacyanoferrate nanoparticles of about 30 nm in size have been prepared by the sonochemical irradiation of a mixture of aqueous potassium ferricyanide and copper chloride solutions. The nanoparticles were immobilized ...
Mimetic biosensors composed by layer-by-layer films of phospholipid, phthalocyanine and silver nanoparticles to polyphenol detection
(2016-10-05)
Highly selective and sensitive modified electrodes have been the focus of many studies in sensing applications. Gene or enzymatic biosensors are greatly effective in this context, but they are often fragile and expensive. ...
Desenvolvimento de um biossensor bienzimático amperométrico para detecção de β-lactose através de filmes nanoestruturados layer-by-layer (LbL)
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-So, 2014-02-28)
In this work the immobilization of enzyme β-Galactosidase has been investigated with use of assembly technique of nanostructured films denominated LbL (Layer-by-Layer) for employment in an amperometric biosensor of ...
Silk fibroin organization induced by chitosan in layer-by-layer films: Application as a matrix in a biosensor
(Elsevier Sci Ltd, 2017)
In this paper, we show that chitosan may induce conformation changes in silk fibroin (SF) in layer-by-layer (LbL) films, which were used as matrix for immobilization of the enzyme phytase to detect phytic acid. Three ...
Phytase immobilization on modified electrodes for amperometric biosensing
(ELSEVIER SCIENCE SA, 2008)
Phytase (myo-inositol hexaphosphate phosphohydrolase) and phytic acid (myo-inositol hexaphosphate) play an important environmental role, in addition to being a health issue in food industry. Phytic acid is antinutritional ...
Nanostructured polyaniline thin films as urea-sensing membranes in field-effect devices
(ElsevierLausanne, 2013-07)
We report the development of a urea biosensor based on a separative field-effect structure containing polyaniline in nanostructured form. Urea is normally produced by the nitrogen metabolism in the body, but its excess is ...
