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 ...
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. ...
A novel label free immunosensor based on single-use ITO-PET electrodes for detection MAGE1 protein
(Elsevier Science Sa, 2017)
This study is aimed to design a label free biosensor based on transparent ITO-PET (Indium tin oxide-polyethylene terephthalate) electrode to determine MAGE1 protein. Firstly, indium tin oxide (ITO) electrodes were modified ...
Quantification of Trypsin Activity by a New Biosensing System Based on the Enzymatic Degradation and the Destructive Nature of Trypsin
(Springer, 2017)
Trypsin is an enzyme that is included in the hydrolysis class of enzymes. Trypsin catalyzes the cleavage of proteins from a serine residue and is found in the digestive system of vertebrates. The cystic fibrosis, which is ...
A novel impedimetric disposable immunosensor for rapid detection of a potential cancer biomarker
(Elsevier, 2014)
A specific and sensitive biosensor was developed successfully for quantitative detection of human epidermal growth factor receptor by electrochemical impedance spectroscopy. Anti-human epidermal growth factor receptor ...
