Porous sensors for real-time monitoring of water quality risks

Objective

The unpredictable contamination of microbial communities in aquatic environments is a global concern for drinking water suppliers and aquaculture producers. Drinking water treatment expenditures, mainly caused by excessive proliferation of harmful cyanobacteria can cost over €150 million/year in European countries. The scenario aggravates when considering the debilitating attacks from pathogenic bacteria in aquaculture cages, generating global economic losses of over $25 billion. In both industrial sectors, the mitigation costs scales with microbial detection delay.

Existent monitoring solutions for water quality mostly rely on time-consuming and operator-dependent measurements of nitrogen and phosphorus fractions, temperature and dissolved oxygen or in using chlorophyll a as a proxy. Yet, these approaches fail to deliver effective and real-time detection of microbial contamination.

Within the ERC-funded GREEN project we have identified a promising commercial application which by means of ultrasensitive electrophysiology allows unprecedent real-time detection of harmful microorganisms in aquatic environments. An international patent has been filed and two research articles published. In addition, two distinct industrial partners and a state laboratory are committed to support and actively participate in PROTEGE.

The breakthrough has been realised by the development of ultra-sensitive porous conducting polyurethane foams which exploits the large electrode area, maximizing the double-layer capacitance and concomitant microbial detection sensitivity. The main aim of PROTEGE is to demonstrate a working prototype in the industrial partners facilities, capable of real-time detection of cyanobacteria in water-supply reservoirs and pathogenic bacteria in aquaculture cages, and to develop a business and exploitation plan for technology commercialization of a market-oriented prototype with real-time telemetry data.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

Host institution

UNIVERSIDADE DE COIMBRA
Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
