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, ...
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 ...
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 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 ...
A Biosensor Based on Zucchini (Cucurbita Pepo L.) Homogenate as a Biorecognition Layer for Ascorbic Acid Determination
(Informa Healthcare, 2010)
An amperometric biosensor based on zucchini (Cucurbita pepo) tissue homogenate is presented. The zucchini tissue homogenate was crosslinked with gelatine using glutaraldehyde and fixed on a pretreated teflon membrane. The ...
Detection of Parathyroid Hormone Using an Electrochemical Impedance Biosensor Based on PAMAM Dendrimers
(Wiley, 2015)
This paper presents a novel hormone-based impedimetric biosensor to determine parathyroid hormone (PTH) level in serum for diagnosis and monitoring treatment of hyperparathyroidism, hypoparathyroidism and thyroid cancer. ...
A sensitive and disposable indium tin oxide based electrochemical immunosensor for label-free detection of MAGE-1
(Elsevier Science Bv, 2017)
MAGE-1 (MAGE, for melanoma antigen), was identified by virtue of its processing and cell surface expression as a tumor-specific peptide bound to major histocompatibility complexes which was reactive with autolytic T cells. ...
