Cirsium italicum (Savi) DC. was researched for its phytochemicals for the first time. Two new biflavonoids, 5,5'',7''-trihydroxy-3,7-dimethoxy-4'-4'''-O-biflavone (3), (8,3',4',5'-tetrahydroxy-7-O-alpha-glucosyl ...
A new immobilization procedure for development of an electrochemical immunosensor for parathyroid hormone detection based on gold electrodes modified with 6-mercaptohexanol and silane
(Elsevier, 2015)
Fabrication of a new electrochemical impedance-based biosensor for the analysis of parathyroid hormone (PTH), using self-assembled monolayers (SAMs) of mercaptohexanol and (3-Aminopropyl) triethoxysilane on gold electrodes, ...
Ultrasensitive electrochemical detection of cancer associated biomarker HER3 based on anti-HER3 biosensor
(Elsevier, 2014)
The development of a new impedimetric biosensor for the detection of HER3, based on self-assembled monolayers (SAMs) of 4-aminothiophenol on gold electrodes, is reported. Anti-HER3 was used as a biorecognition element for ...
Review study of electrochemical impedance spectroscopy and equivalent electrical circuits of conducting polymers on carbon surfaces
(Elsevier Science Sa, 2011)
Electrochemical impedance spectroscopy (EIS) is an experimental method for characterizing electrochemical systems. This method measures the impedance of the concerned electrochemical system over a range of frequencies, and ...

New antimony(III) chloride complexes with heterocyclic thioamides, thiourea (TU), 2-mercapto-5-methyl-benzimidazole (MMBZIM), 3-methyl-2-mercaptobenzothiazole (MMBZT), 2-mercaptopyrimidine (PMT), 2-mercaptopyridine (PYT) ...
Copolymer formation of 9-(2-(benzyloxy)ethyl)-9H-carbazole and 1-tosyl-1H-pyrrole coated on glassy carbon electrode and electrochemical impedance spectroscopy
(Springer, 2012)
In this work, 9-(2-(benzyloxy)ethyl)-9H-carbazole (BzOCz) and 1-tosyl-1H-pyrrole (TsP) monomers were chemically synthesized and characterized by Fourier transform infrared reflectance (FTIR) and proton nuclear magnetic ...
An impedimetric vascular endothelial growth factor biosensor-based PAMAM/cysteamine-modified gold electrode for monitoring of tumor growth
(Academic Press Inc Elsevier Science, 2012)
In the present work, we have developed a new biosensor based on fourth-generation (G4) PAMAM dendrimers for the analysis of vascular endothelial growth factor (VEGF). First, the PAMAM dendrimers were covalently attached ...
