What are Nano Enabled Water Sensors?
Nano enabled water sensors are advanced devices that utilize
nanotechnology to detect and monitor various parameters in water. These sensors leverage the unique properties of
nanomaterials to achieve high sensitivity, selectivity, and rapid response times. They are employed to measure contaminants, pH levels, temperature, and other important characteristics of water quality.
How do Nano Enabled Water Sensors Work?
The working principle of nano enabled water sensors involves the interaction of nanomaterials with the target analytes in water. These nanomaterials, such as
carbon nanotubes,
gold nanoparticles, and
quantum dots, exhibit distinct electrical, optical, or chemical properties that change upon binding with specific contaminants or molecules. These changes are then transduced into measurable signals, providing accurate information about the water quality.
