Abstract
There is provided a biosensor for detecting water contaminants. The biosensor has a microbial fuel cell compartment, having (i) at least one opening to allow water into and out of the microbial fuel cell compartment, (ii) an anode comprising electroactive microorganisms, and (iii) a cathode. The anode is electrically and physically separated from the cathode. The anode is anaerobic and comprises electroactive microorganisms. The cathode is aerobic. The biosensor has a storage compartment housing a biodegradable carbon source to supply the biodegradable carbon source to the electroactive microorganisms; an electric impedance load; an electric switch forming an intermittent connection between the microbial fuel cell compartment and the electric impedance load; an electric sensor; and a control system coupled to the electric switch and the electric sensor, receiving a measurement from the electric sensor, and outputting an indication signaling the presence or absence of the water contaminants based on the measurement.
