e-BioSensors
Bioelectrochemical sensors are a promising tool for environmental analysis, as they can provide a continous online signal. Here, long-lasting, low-cost devices are proposed for freshwater and wastewater monitoring, with the use of non-toxic materials and simple construction.
CELL STRUCTURE
Simple construction and low-cost materials allow a wideaspread application of this sensor. Estimated price: 1.70€ for one cell.

Wastewater monitoring
Wastewater monitoring
The bioreceptor is a spontaneous electrogenic biofilm in equilibrium with the environment, which ensures the stability of the sensors for long periods of time, up to few years.
The trend of the current signal can be used as a multipurpose indicator of the environmental quality, as it can be correlated with Biological Oxygen Demand, dissolved oxygen in the water or the presence of toxic compounds such as heavy metals.
