A bioelectronic nose that mimics the human nose can detect traces of bacteria in water by smelling it, without the need for complex equipment and testing. According to a study, the technology works by using the smell receptors in the human nose. The sensor is simple to use and it can detect tiny amounts of contamination in water, making it more sensitive than existing detection methods. The authors of the study say this could make the technology even more useful in the field.
