General information

Reference : UMR5270-MARTAU-001
Date of publication : Friday, October 25, 2019
Type of Contract : FTC Scientist
Contract Period : 18 months
Expected date of employment : 6 January 2020
Proportion of work : Full time
Remuneration : From 2643€ to 3047€ gross monthly
Desired level of education : PhD
Experience required : Indifferent


This position is proposed as part of the collaborative project BELUGA, funded by the ANR and supported by a consortium of three technological laboratories (INL, LAAS, CINaM), an ecotoxicology laboratory (LEHNA) and the company OrigaLys. This project contributes to meet the needs of water quality monitoring actors for low-cost tools allowing more frequent and in-situ monitoring of the environment. For this purpose, we propose to integrate within the same lab-on-a-chip a bio-assay used in ecotoxicology as well as sensors for the physicochemical characterization of the medium. The bioassay is based on the evaluation of the photosynthetic apparatus state of unicellular algae via an optical measurement. The lab-on-a-chip will be designed in a way to be usable autonomously by the operator performing the measurement in the field without resorting to any infrastructure. A "lab-on-disk" approach was chosen because of its potential to respond effectively to this challenge.


The postdoc will participate in the design, implementation and characterization of the lab-on-disk for the handling and characterization of unicellular algae suspensions. After the design of the microfluidic network, he / she will participate in its realization by direct micro-milling in polymer substrates or by micro-machining of metal molds for hot embossing. He / she will also participate in the integration of optical sensors and sources produced by the other members of the consortium and participate in the evaluation of the metrological performance of the system. An interaction with the company OrigaLys will be necessary to ensure compatibility with its own instrumental system.


The candidate will have experience in the design and implementation of microfluidic systems. More specific skills in all or some of the following areas would be very significant for the project: knowledge of the physics of microfluidic flows, realization by micro-milling on polymer substrate or metal substrate, lab-on-disk, electronics and instrumentation.

Work Context

The recruited person will join the LOCI team (Lab-On-Chip & Instrumentation) of the “Institut des Nanotechnologies de Lyon” (INL, UMR CNRS 5270, of the University Claude Bernard at Lyon. This eight permanent members team specializes in the development of microfluidic tools for health and environment. The technical resources available are those of the NanoLyon platform, which includes all the necessary micro / nano manufacturing tools. The research activity of this project is the result of a multi-year collaboration between the INL and the “Laboratoire d'Ecologie des Hydrosystèmes Naturels et Anthropisés” (LEHNA, UMR CNRS 5023, Vaulx-en-Velin). LEHNA is among others specialized in the development of whole cell sensors for water quality monitoring.
