Développement d'une mesure électrochimique aux limites pour application biocapteurs :

Des travaux précédents ont démontré les possibilités d’une mesure électrochimique via une mesure haute fréquence (GHz), permettant d'atteindre des résolutions en courant faradique de l'ordre de l'attoampère (10^-18 A)[1–3]. Il a également été démontré qu'une mesure basée sur le bruit shot-noise faradique était possible [4]. L'enjeu est ici de transférer ces techniques à une mesure compatible avec les technologies sur puce via une architecture en guide d'onde coplanaire, d’évaluer leurs sensibilités, d’évaluer les possibilités de combiner les techniques, ainsi que de de les confronter à des échantillons biologiques réels, allant au-delà de la simple preuve de concept sur entité électrochimiques sans fonctions biologique.

Development of an Electrochemical Measurement at the Limits for Biosensor Applications

Previous work has demonstrated the potential of electrochemical measurement using high-frequency (GHz) techniques, achieving faradaic current resolutions on the order of attoamperes (10^-18 A) [1-3]. It has also been shown that measurement based on faradaic shot noise is possible [4]. The challenge now is to transfer these techniques to a chip-compatible measurement system using a coplanar waveguide architecture, assess their sensitivities, evaluate the possibilities of combining them, and test them with real biological samples—going beyond simple proof-of-concept demonstrations on electrochemical entities without biological function.

We are looking for a motivated candidate passionate about a project at the intersection of electrochemistry and high-frequency instrumentation. Ideally, you have a basic understanding of electrochemistry and/or electronics, along with signal processing skills, enabling you to actively contribute to the development of innovative experiments.

Your responsibilities will include designing and conducting experiments that combine electrochemistry, high-frequency (GHz) measurements, and noise analysis, as well as fabricating waveguides and electrodes for electrochemistry in a cleanroom environment.

Beyond technical skills, we highly value your scientific curiosity and ability to explore original approaches, as well as your commitment to an interdisciplinary project where autonomy and creativity will be key strengths.

This project sits at the crossroads of quantum chemistry, high-frequency electronics, and the development of innovative sensors. Candidates who demonstrate motivation and a willingness to engage deeply in these fields will be especially appreciated.
