Journal ArticleDOI
Development of an impedimetric aptasensor for the determination of aflatoxin M1 in milk
Georges Istamboulie,Nathalie Paniel,Lorena Zara,Lucia Reguillo Granados,Lise Barthelmebs,Thierry Noguer +5 more
TL;DR: An aptasensor was designed for the determination of aflatoxin M1 (AFM1) in milk based on DNA-aptamer recognition and electrochemical impedance spectroscopy detection and application to milk analysis showed that a preliminary treatment was mandatory.
Journal ArticleDOI
Sensitive quantitation of Ochratoxin A in cocoa beans using differential pulse voltammetry based aptasensor
TL;DR: The proposed method, biotin labeled and free OTA competed to bind with immobilized aptamer onto the surface of a screen printed carbon electrode (SPCE), and percentage binding was calculated, demonstrating the efficiency of proposed aptasensor for such matrices.
Journal ArticleDOI
Highly sensitive detection of organophosphorus insecticides using magnetic microbeads and genetically engineered acetylcholinesterase.
TL;DR: The oriented and site-specific immobilisation combined with the high specificity of the B349 mutant allows a more sensitive detection of insecticides, concentrations as low as 1.31(-11)M (IC10) being detected for both pesticides chlorpyriphos-oxon and chlorfenvinphos.
Journal ArticleDOI
Disposable and portable aptamer functionalized impedimetric sensor for detection of kanamycin residue in milk sample
Atul Sharma,Atul Sharma,Georges Istamboulie,Akhtar Hayat,Akhtar Hayat,Gaëlle Catanante,Sunil Bhand,Jean-Louis Marty +7 more
TL;DR: In this article, a facile, label free and portable aptasensor for quantitative determination of Kanamycin (KANA) by electrochemical impedance spectroscopy (EIS), which accompanying the assembly of in-vitro selected single strand DNA (ssDNA) anti-KANA-aptamer functionalized screen printed carbon electrodes (SPCEs) used as transducer.
Journal ArticleDOI
Screen-printed poly(3,4-ethylenedioxythiophene) (PEDOT): A new electrochemical mediator for acetylcholinesterase-based biosensors
Georges Istamboulie,Tomasz Sikora,Elena Jubete,Estibalitz Ochoteco,Jean-Louis Marty,Thierry Noguer +5 more
TL;DR: The high conductivity of PEDOT:PSS allowed the accurate detection of the organophosphate insecticide chlorpyrifos-oxon at concentrations as low as 4x10(-9)M, corresponding to an inhibition ratio of 5%.
