Note: According to WHO, in 2018, more than 100,000 chemicals were released into the global environment due to their production, use, and disposal. In this regard, water is the key element for their effective transport in the food chain and since remediation can be extremely difficult, such pollution is leading to acute or chronic toxicity in aquatic organisms, loss of habitats and biodiversity as well as human diseases. But, industrial wastewater flows contain hazardous and toxic species that are not easy to process, and treatment installations need extremely reliable and sensitive sensing solutions to continuously monitor the efficiency of the side stream treatment processes. At the same time, the world population is increasingly depending on aquaculture for nutritious food. Frequent analysis of the water quality is essential and needs to be performed at point-of-testing, not in remote laboratories. The common challenges in environmental control, wastewater management and aquaculture are that, in small sample sizes, species need to be detected that are present in very low concentrations, with a technique that can be performed at point-of-testing, at low cost and in a minimum of time. In the last decade, new sensor technologies have emerged that can meet these challenges. These sensors however require the sample to flow over the sensor surface and, importantly, detection is only possible if the target species in flow makes contact with the sensor surface. This is one of the key technological hurdles that today’s microfluidics sensors have not overcome yet. In VORTEX SENSOR vortices will be induced in the flow channel with acoustic streaming, an approach which was developed in ERC Starting Grant EVODIS. This will enable long range transport of compounds towards the sensor surface. In VORTEX SENSOR a prototype of the very first biosensor with vortex microflow inducer will be built and its performance will be validated with two relevant pathogens for aquaculture of salmon.
