Caption

A diagram of the SION-105 prototype device: A vial containing a red luminescent suspension of SION-105 crystals is placed inside the device. When two drops of water sample are added to the vial, resulting changes in the brightness of SION-105 are measured by the photodiode, and instantly converted into an accurate quantitative reading of the fluoride concentration in the sample. The inset is a schematic of how the luminescence is quenched at the molecular level. Credit: Mish Ebrahim
