Job description

Topic background 

Water contamination affects animal life and threatens the supply of clean drinking water in the future. Monitoring of water quality at water treatment facilities and in surface water will allow the identification of excesses and enable timely response. Currently, there are no sensors to measure low concentrations of micropollutants, e.g. hazardous pharmaceuticals, pesticides, other chemicals, or nutrients such as phosphate and nitrate.

TU/e develops single-molecule optical sensors for monitoring biomolecules in both healthcare and environmental applications. The sensors monitor functionalized particles in a miniature imaging system, whose motion responds to the presence of a specific micropollutant/nutrient. This enables continuous monitoring, is extremely specific, and consumes no reagents. This will provide a game changer in the remote monitoring of surface water for e.g. eutrophication, illegal discharges, and contamination at sewage treatment facilities.

The project 

You will translate the sensing principles developed at TU/e, into a multiplexed optical prototype for two analytes that achieves long-term optical sensor stability in realistic surface water conditions. This requires developments in (a) the miniaturization of the read-out optics to achieve a highly miniaturized and stable interferometric microscope, (b) integration of electronics, and (c) multiplexing. You will develop a miniaturized interferometric microscope for single-molecule sensing with co-integrated sensors (e.g. temperature, electrical conductivity) that will be used to enable multiplexed sensing and background calibration. You will develop and characterize the sensor in the lab, integrate it into a device, and field-test it.

The research groups

This project will combine the expertise of Wetsus in water technology, and the expertise of TU/e in optical sensing. You will be stationed at Wetsus in Leeuwarden, and closely collaborate with researchers at TU/e.

Wetsus, European centre of excellence for sustainable water technology is a facilitating intermediary for trendsetting know-how development. Wetsus creates a unique environment and strategic cooperation for development of profitable and sustainable state of the art water treatment technology. Wetsus’ scientific research program is defined by the private and public water sector, devided into 23 research themes and you will be part of the research theme Sensoring. Around 60 PhD researchers are housed in Leeuwarden. Wetsus has a well-equipped analytical and optical laboratory, and has scientific, analytic and technical staff to support the research.

You will closely collaborate with the Molecular Biosensing research group at the Department of Applied Physics at TU/e. The group hosts ~40 researchers that share facilities and meets weekly. The group performs leading research on optical single-molecule sensing technologies, focusing on particle-based optical sensors. The multidisciplinary team hosts physicists, chemists, and biomedical engineers collaborating in a close-knit team. The lab hosts a range of state-of-the-art single-molecule microscopes in optical laboratories and wet-chemical labs where sensors are functionalized and integrated with fluidics.
