Quantum-powered water sensor for detecting ultra-low concentrations of hormone pollutants

environmentTestedTRL 5

Imagine a super-sensitive flashlight and a high-tech camera that can spot a single tiny speck of dust in a swimming pool. This technology uses quantum dots and DNA structures to create a light source that is incredibly quiet and precise. It allows people to find harmful hormones in water without needing a giant laboratory or a PhD to run the machine.

The business problem

What needed solving

Current water monitoring for endocrine disruptors often requires expensive laboratory equipment and highly trained staff. There is a lack of robust, on-site tools capable of detecting these pollutants at extremely low concentrations.

The solution

What was built

A compact spectrometer featuring an electrically pumped single photon source and a thermoelectric-cooled detector. It includes a microfluidic flow cell for sample handling.

Who can put this to work

Aquaculture
SME
Target: Commercial fish farm operator

If you are a fish farm operator dealing with endocrine disruptors affecting fish growth — this project developed a compact spectrometer that detects contaminants in the sub ng/L range. This allows you to monitor water safety on-site without needing external infrastructure.

Water Management
enterprise
Target: Municipal water treatment plant

If you are a water utility dealing with strict regulations on drinking water purity — this project developed a low-noise detection method using single photon sources. This enables the measurement of the lowest absorptions of hormones to ensure public health safety.

Environmental Monitoring
mid-size
Target: Environmental consultancy firm

If you are a consultancy dealing with nature conservation monitoring — this project developed a robust, ready-to-use biosensor for the Vis to NIR range. This allows for field tests of water quality without requiring trained personnel on-site.

Frequently asked

Quick answers

What is the estimated cost or price of the device?

Based on available project data, the specific unit price is not mentioned, but the system is designed to be compact and avoid expensive cryogenic coolers by using simple thermoelectric cooling.

Can this be produced at an industrial scale?

The project involves 5 industrial partners and 4 SMEs, suggesting a focus on scalable manufacturing of the LED layer stack and nanocomponents.

What is the IP and licensing situation?

Based on available project data, specific licensing terms are not provided, but the project is managed by TU Chemnitz with a dedicated work package for dissemination of knowledge and results.

How does it integrate into existing water workflows?

The system includes a microfluidic flow cell and a sample concentration method, allowing it to be used as a ready-to-use, on-site monitoring tool.

What is the timeline for market availability?

The project period runs from 2023-01-01 to 2026-06-30, indicating that the final validated demonstrator will be ready by mid-2026.

Consortium

Who built it

The consortium is heavily industry-weighted with a 62% industry ratio, comprising 5 industrial partners (including 4 SMEs) and 3 academic/research entities. This structure, spanning 4 countries (DE, ES, FR, IT), indicates a strong push toward commercialization and practical application rather than purely theoretical research.
