Summary
The objective of this internship is to develop innovative electrochemical devices for the detection of various water pollutants. The aim is to enhance their performance and selectivity through the use of cage molecules and nano-objects with unique properties.
Full description
Water pollution is a matter of concern due to the real medium-term risk of losing access to drinking water—a vital resource. Consequently, the development of high-performance, user-friendly analytical tools appears essential for monitoring water quality.
We are developing at LEDNA innovative electrochemical devices based on liquid-liquid microinterfaces. Their unique feature is the ability to detect charged species via transfer between two phases but without an electrochemical reaction using simple, conventional electrochemical measurements. These transfers can be direct or assisted by the addition of molecules to enhance selectivity.
Since many years, LIONS develops novel cage molecules and porous nano-objects that possess highly specific supramolecular properties and reactivities tunable at the nanoscale. These chemical entities appear highly promising for electrochemical devices, offering a way to optimize the transfert of targeted pollutants and enhance the specificity of their detection.
The objectives of this internship, relying on complementary areas of expertise, will therefore be to:
• Perform electrochemical measurements in the presence of these molecules and nano-objects, and study their behavior in simple cases (model solutions).
• Select specific chemical entities based on the relevant target pollutants already well-studied in the laboratory (pharmaceuticals, pesticides, persistent pollutants, etc.).
• Determine optimal detection conditions for one or two pollutants of interest in various types of water for practical applications.
