Zonal selectivity by sensitivity modulation in linear tetrapolar impedance sensors

Moretti, Fabián N.; Cabrera, Jorge L.; Madrid, Rossana Elena (Elsevier Science Sa, 2018-02)

This work investigates the behaviour of a tetrapolar impedance sensor due to sensitivity issues caused by inherent method measurement when inter-electrode spacing is changed. Finite Element Method (FEM) modelling of the ...

Electrochemical Behavior of Screen-Printed Carbon Electrodes as Transducers in Biosensors

Universidade Federal de Minas Gerais (UFMG); Univ Laval; Fundacao Ezequiel Dias FUNED; Universidade Estadual Paulista (Unesp) (Natl Assoc Corrosion Eng, 2020-06-01)

Screen-printed carbon electrode (SPCE) was examined as a transducer substrate for application in electrochemical sensors. Aqueous solutions of 0.1 M KCl and 0.1 M KCl + 5 mM K-3[Fe(CN)(6)]/K-4[Fe(CN)(6)] (redox solution) ...

Hybrid Layer-by-Layer Film of Polyelectrolytes-Embedded Catalytic CoFe2O4 Nanocrystals as Sensing Units in Capacitive Electrolyte-Insulator-Semiconductor Devices

Federal University of Triângulo Mineiro (UFTM); Universidade Estadual Paulista (Unesp); Federal University of Alagoas (UFAL); FH Aachen University of Applied Sciences; Research Center Jülich GmbH (2019-06-19)

Nanostructured materials have exhibited great potential applications in the field of (bio)sensing. In particular, the capacitive electrolyte-insulator-semiconductor (EIS) sensor is a suitable field-effect device for ...

Layer-by-Layer Films with CoFe2O4Nanocrystals and Graphene Oxide as a Sensitive Interface in Capacitive Field-Effect Devices

Federal University of Triângulo Mineiro (UFTM); Universidade Estadual Paulista (UNESP); FH Aachen; Forschungszentrum Jülich (2022-01-01)

Sensor devices have proved to be a promising technology for portable microelectronic systems for biomedical and environmental applications. Depending on the target analyte and/or the sensor platform chosen, the study of ...

Photochemiresistor Sensor Development Based on a Bismuth Vanadate Type Semiconductor for Determination of Chemical Oxygen Demand

Universidade Estadual Paulista (Unesp) (2020-04-22)

The present paper describes the development of a novel photochemiresistor sensor for the determination of chemical oxygen demand (COD). A chemiresistive device was produced by a thin film of the monoclinic phase of bismuth ...

Non-enzymatic impedimetric sensor based on 3-aminophenylboronic acid functionalized screen-printed carbon electrode for highly sensitive glucose detection

Universidade Federal de Minas Gerais (UFMG); Université Laval; CDN Isotopes; Fundação Ezequiel Dias (FUNED); Universidade Estadual Paulista (Unesp) (2019-04-01)

A highly sensitive glucose sensor was prepared by a one-step method using 3-aminophenyl boronic acid as a unit of recognition and a screen-printed carbon electrode (SPCE) as an electrochemical transducer. Scanning Electron ...
