Detection of Alzheimer’s disease amyloid-beta plaque deposition by deep brain impedance profiling

Philippe Renaud, Patrick Fraering, Amélie Barbara Hildegarde Béduer, Pierre Joris, Sébastien Mosser

OBJECTIVE: Alzheimer disease (AD) is the most common form of neurodegenerative disease in elderly people. Toxic brain amyloid-beta (ASS) aggregates and ensuing cell death are believed to play a central role in the pathogenesis of the disease. In this study ...

Polyimide foam-like microstructures: technology and mechanical properties

Martinus Adela Maria Gijs, Philippe Renaud, Sébastien Jiguet, Pierre Joris, Jagoda Anna Dobrzynska

We report a process for the realization of polyimide films with custom-designed microporosity based on the heat-induced depolymerization of polyimide-embedded polypropylene carbonate microstructures. The foam-like microstructures are up to 40 µm thick and ...

Accurate resistivity mouse brain mapping using microelectrode arrays

Philippe Renaud, Patrick Fraering, Vincent Delattre, Amélie Barbara Hildegarde Béduer, Pierre Joris, Sébastien Mosser

Electrical impedance spectroscopy measurements were performed in post-mortem mice brains using a flexible probe with an embedded micrometric electrode array. Combined with a peak resistance frequency method this allowed obtaining intrinsic resistivity valu ...

A microfluidic-based frequency-multiplexing impedance sensor (FMIS)

Philippe Renaud, Arnaud Bertsch, Robert Meissner, Pierre Joris, Bilge Eker

We present a novel technology for the simultaneous and simple impedimetric screening of multiple microfluidic channels with only one electrode pair. We have exploited the frequency dimension to distinguish between up to three channels. Each ‘sub-sensor’ po ...
