PhD position - Colorimetric detection of organophosphorus based pesticides: From organic synthesis to colorimetric paper detector

JOB DESCRIPTION

SL-DRT-20-0714

RESEARCH FIELD

ABSTRACT

This PhD thesis deals with the design and synthesis of chromogenic dyes and the processing method needed for the development of chromogenic detector of organophosphorus pesticides.A chromogenic dye is a molecule that changes color when it is in the presence of a target molecule.At the CEA Grenoble, the LSIN laboratory has developed an expertise around the colorimetric detection, via the screening of a chemical library of commercial chromogenic dyes. We identified commercial reactive structures.The aim of this thesis is to synthesize more reactive structural analogues with controlled color change.It is proposed to validate the actual color changes on organophosphorus pesticides.Finally, the study of the reactivity of chromogenic dyes versus organophosphorus pesticides (NMR, FTIR, UV-vis-NIR, mass spectrometry, …) should allow us to better understand their reactivity and propose a reaction mechanism explaining the color changes observed.A prototype of a low-cost organophosphorus pesticide colorimetric detector will be developed at the end of the thesis.
