New Simple Test Could Detect Dangerous Levels of Fluoride in Drinking Water

Northwestern University synthetic biologists developed a simple, inexpensive new test that can detect dangerous levels of fluoride in drinking water. Costing just pennies to make, the system only needs a drip and a flick: Drip a tiny water droplet into a prepared test tube, flick the tube once to mix it and wait.
