Interdigitated electrode DNA biosensor for detection of food-borne pathogens by impedance spectroscopy

Daniel Berdat

The commercial application of biosensors has had a significant impact in a number of areas, particularly in the field of medical diagnostics. But in spite of the great number of publications, only a few systems are commercially available in food analysis. ...

Label-free detection of DNA with interdigitated micro-electrodes in a fluidic cell

Martinus Adela Maria Gijs, Daniel Berdat

We investigate the analytical performance of an interdigitated electrode sensor for the label-free detection of DNA, by monitoring the complex impedance of 5 µm wide interdigitated Pt microelectrodes on a glass substrate. We detect the hybridization of unl ...

DNA biosensor using fluorescence microscopy and impedance spectroscopy

Martinus Adela Maria Gijs, Daniel Berdat

Two types of DNA biosensors are presented. Both sensing principles are demonstrated using synthetic oligomer single-stranded DNA (ssDNA) with concentrations in the micromolar range. A first sensor type is based on the detection of fluorescently labeled ssD ...

Contactless electrochemical actuator for precise sampling on microchip

Martinus Adela Maria Gijs, Daniel Berdat, Lynda Metref

The scope of this work has been the design of a mechanical actuator in polydimethylsiloxane (PDMS) / glass for precise liquid sampling, based on the electrochemical generation of O2. The device is composed of two chambers separated by a PDMS membrane. In t ...
