Development of an impedimetric aflatoxin M1 biosensor based on a DNA probe and gold nanoparticles
(Elsevier Advanced Technology, 2011)
The present work describes the construction and application of a new DNA biosensor for detection of aflatoxin M1. In order to immobilize a thiol-modified single stranded DNA (ss-HSDNA) probe that specifically bound aflatoxin ...
A novel, ultra sensible biosensor built by layer-by-layer covalent attachment of a receptor for diagnosis of tumor growth
(Elsevier, 2011)
In the presented research, a novel, ultra sensitive biosensor for the impedimetric detection of vascular endothelial growth factor (VEGF) is introduced. The human vascular endothelial growth factor receptor 1 (VEGF-R1, ...
Capacitive behaviors and Monomer Concentration Effects of Poly(9-benzyl-9H-carbazole) on Carbon Fiber Microelectrode
(Korean Fiber Soc, 2011)
In this work, 9-benzyl-9H-carbazole (BzCz) monomer was chemically synthesized by a new process. It was electrocoated on carbon fiber microelectrode (CFME) as an active electrode material in 0.1 M sodium perchlorate ...
Beta-galactosidase Determination by an Electrochemical Biosensor Mediated with Ferrocene
(Informa Healthcare, 2011)
In this paper, a new viewpoint on the activity determination of beta-galactosidase is reported. Glucose oxidase was directly immobilized on a glassy carbon electrode and mediated by ferrocene. The biosensor's performance ...
Glutathione (GSH) Determination by a Very Simple Electrochemical Method
(Springer, 2011)
Glutathione (GSH; gamma-glutamylcysteinylglycine) is ubiquitous in mammalian and other living cells. It contains an unusual peptide linkage between the amine group of cysteine and the carboxyl group of the glutamate side ...
Antioxidant Activity and Total Phenolic Content of Gagea fibrosa and Romulea romiflora
(Jihad Daneshgahi, 2011)
Free radicals involved in a number of diseases due to the oxidative damage to DNA, lipids, and proteins and which can result in failure of cellular functions. Dried plant bulbs and leaves methanolic and ethanolic extracts ...
Construction and Comparison of Trametes versicolor Laccase Biosensors Capable of Detecting Xenobiotics
(Informa Healthcare, 2010)
Amperometric biosensors using laccase from Trametes versicolor as a bioelement were developed for 2,4-dichloro phenoxy acetic acid (2,4-D). Laccase enzyme was immobilized by gelatin and glutaraldehyde onto a Clark oxygen ...
A New Voltammetric Method for the Determination of Lercanidipine in Biological Samples
(Slovensko Kemijsko Drustvo, 2011)
Electrochemical behavior and adsorption-diffusion properties of lercanidipine (LCN) on a glassy carbon electrode (GCE) were investigated in a mixture of ethanol-Britton Robinson buffer (BR) using voltammetric methods. From ...
A new impedimetric biosensor utilizing VEGF receptor-1 (Flt-1): Early diagnosis of vascular endothelial growth factor in breast cancer
(Elsevier Advanced Technology, 2011)
A new impedimetric biosensor, based on the use of vascular endothelial growth factor receptor-1 (VEGF-R1), was developed for the determination of vascular endothelial growth factor (VEGF). VEGF-R1 was immobilized through ...
A Biosensor for the Determination of beta-galactosidase Activity: A Different Viewpoint on Biosensors
(Informa Healthcare, 2011)
beta-galactosidase splits lactose into glucose and galactose. Because of its biotechnological interest, we presented a biosensor system in order to monitor beta-galactosidase activity. Immobilization steps of the biosensor ...
