Thesis Title:

Development of a Lab-on-a-Chip for Heavy Metal Detection in Water: From Quantum Dots to Integrated Plasmonic Sensors

Research Context:

This project is motivated by the global health challenges posed by water pollutants, specifically heavy metals like Chromium (VI) and Mercury (II), which have been identified by the World Health Organization as among the top ten chemicals of major public health concern. The proposed research aims to integrate high-precision pollutant detection technologies directly into a chip, facilitating in-situ monitoring and potentially revolutionizing environmental surveillance.

Project Description:

The doctoral candidate will develop a low-cost, lab-on-a-chip sensor using Surface Plasmon Resonance (SPR) technology. This will involve the application of Quantum Dot (QD) multi-layer Quantum Light Emitting Diodes (QLEDs) for creating a highly selective and sensitive detection mechanism. The research will focus on enhancing luminescence efficiency through the integration of gold nanoparticles and optimizing the sensor design for real-world application.

Academic and Industrial Collaborations:

This thesis will be conducted under the guidance of Prof. Isabelle Bord Majek and Dr. Laurent Oyhenart at IMS (UMR 5218), WAVES research group. The project is in collaboration with ICMCB and leading industry partners, Chromatotec and Hemera, providing a rich environment for interdisciplinary and applied research.

Candidate Profile:

  • Master’s degree in Engineering or Master of Science with specialization in physico-chemistry, physics, materials science, or optics.
  • Demonstrable interest in environmental science and sensor technology.
  • Proficiency in experimental physics and instrumentation.
  • Strong analytical skills and a commitment to scientific excellence.

Application Process:

Interested candidates should submit a detailed CV, a motivation letter, and at least two references to Prof. Isabelle Bord Majek ( and Dr. Laurent Oyhenart ( Applications will be accepted until the position is filled.
