>> Postdoctoral position: Development of a biosensor for pesticide detection

Publication: From December 10, 2018 to January 30, 2019

Project description

A wide variety of organic pollutants are found in natural and treated water sources, such as

pesticides. Traditional methods for their detection and quantification involve mass spectrometry, often in combination with gas or liquid chromatography. Since these methods are expensive, time-consuming, require a skilled labour, and are not suitable for on-site analyses, current research efforts are devoted to develop disposable sensors based on specific targeting coupled to colorimetric, fluorescence, or electrochemical detection. However, an emerging method involving DNA aptamers for pollutant detection is currently explored. These nucleic acids have been widely used as recognition elements for biosensor construction, especially in the detection of pathogens (Escherichia coli), drugs (cocaine), hormones (β-estradiol), organic pollutants (bisphenol-A), etc.

In this project, the main objective is to develop an aptamer-based biosensors for on site and real time analyses of pesticides. An electrochemical platform based on a screen-printed electrodes will be explored. Different strategies will be evaluated to immobilize the aptamer on the surface.

Keywords: Biosensor, aptamer, pesticide, electrochemistry

Working conditions

Hosting laboratory:  IPREM, UMR CNRS 5254, Université de Pau et des Pays de l’Adour.

Localisation address: IPREM, Technopôle Helioparc, Pau, France

Starting period: Beginning of 2019

Duration: one year

Gross salary range: 2665 €/month.

Funding: This post doc position is funded by the E2S-UPPA project (Energy Environment Solutions) of core scientific domain focused on Environment and Energy to meet challenges related to the energy transition, geo-resources, aquatic habitats and the environmental effects of natural and anthropogenic changes.
