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 ...
Electrochemical immunosensors based on quantum dots
(Elsevier, 2021)
The use of quantum dot-based electrochemical immunosensors in a wide perspective from disease markers to agriculture has gained importance in recent years. Due to this importance, many signal amplification strategies have ...
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 ...
Immobilization of anti-aflatoxin B1 antibody by UV polymerization of aniline and aflatoxin B1 detection via electrochemical impedance spectroscopy
(Informa Healthcare, 2012)
In the study, we investigated the practicality of the UV polymerization of aniline for anti-aflatoxin B1 antibody immobilization, and utilization of the resulting biosensor in the impedimetric determination of aflatoxin ...
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 ...
