Human activity has led important quantities of chemical pollution (colorants, synthetic intermediates, phytosanitary products, drugs,…). Among them, persistent organic pollutants (POP) are one main source for intoxication that are “consciously” spread in natural environments and are mostly produced by intensive farming and soil overexploitation agriculture. Faced to such global public health challenge, there is an urgent need for new tool developments in soil and water pollution monitoring. Moreover, such new tools shall be both generic to the largest group of POP but also cost-effective to lower the average cost per analysis to spread such a technology largely.
The French Reseach Agency (ANR) project “Sens-Pestols” aim developing organic electrochemical transistors (OECT) for POP detection, kepone more particularly, which is massively spread in Antilles banana plantations and makes an important sanitary scandal today. Those sensors will be functionalized with next-gen biochemical probes such as antibodies and aptamers. The studied environments composition being complex for containing various kind of polluting chemicals, using the devices multi-parametric sensitivity is a prerequisite to discriminate rich blends. Multi-variate data analysis on co-integrated multi-materials micro-sensor array will be performed. Although the methodology is generic and low cost, the challenge will lie on identifying an appropriate process to co-integrate each sensor marked with one unique and functional POP-specific probe.
On the long term, these new tools shall enable online monitoring for contaminated soil and water, track polluted areas to plan soil preventive and curative actions to control the overall consumer transmission chain and protect the population may be directly exposed.
In the Sens-Pestols project framework, we are looking for a talented engineer (IE) who is going to work on technological development of biomaterials co-integration on electronic sensors. He or she will autonomously carry on an interdisciplinary research work package from biological probes functionalization, surface characterization in a cleanroom environment, co-integrating them on electrochemical micro-sensors, and selectivity/sensitivity assessment by electrical tests on sensors. Although the main activity is centered on surface biofunctionalization in a cleanroom environment with physical/chemical characterization, he/she should be able to interact with other colleagues' expertise in biology, biochemistry and chemistry.
The candidate should have a degree in one of the above-mentioned discipline necessary to carry on the project: device/electronics and/or material sciences and/or electrochemistry and/or micro/nanofabrication. All skills are required for the mission (Master's degree or an equivalent engineering degree preferred). Additionally, competences bio/nano interfacing will be an asset. In general, the candidate shall have a core academic knowledge and a personal interest for interdisciplinary research.
The mission will take place at the Institute for Electronic, Microelectronic and Nanotechnologies (IEMN) in Villeneuve d'Ascq/France. IEMN is a join-research institute from CNRS (French Scientific Research Council), two universities, and an engineering school in the Hauts-de-France region. IEMN's microfabrication and characterizations facilities are at high-rank EU-level. IEMN is a 500+ people institute with 109 professors/associate-processors, 45 tenured CNRS researchers, 100+ engineers and administrative staffs, 150+ PhD students and 30+ post-docs and invited researchers. The lab is involved in many international research initiatives with 100+ foreign researchers at IEMN from 20+ countries abroad. IEMN's scientific activities includes broad domains from materials' physics, micro-wave structures, telecommunications, and acoustic instrumentations.
Constraints and risks
All experiments (chemical and biochemical materials) will be conduct complying CNRS' risk and safety rules at IEMN, moreover in glovebox and protective outfits. A training of specific technological resources will be provided, as well as the appropriate risk and safety guidance accordingly. An approval for entering in a national restrictive regime area (ZRR) will be required to fulfill the position.
