Sixsenso is a young biotechnology company that aims to change how water contamination is monitored worldwide. Our aim is to offer an environmental solution bringing the lab to the origin of water contamination by a rapid and robust microorganism monitoring tool which works as an early alarm to stop waterborne pathogens outbreaks. The system is based on the application of light to detect fluorescence emitted both naturally and by induced labelling techniques emitted by microorganisms. It comprises an automatic microfluidic labelling system and a fluorescence reader system, both coupled to a front end sample concentrator system which takes the target waters under investigation and converts them into a useful volume for system analysis. It is designed to be extremely accurate, portable, cost-effective, and easily integrable within a process stream or for on-site measurements with a time to result one order of magnitude lower than gold standard methods. It is suitable for phytoplankton and specific bacteria monitoring in bathing water, harbour water and ballast water regulations compliance, with direct applicability in waste water, industrial water, fresh water and beverage quality control.
