Colorimetric sensor arrays for the detection of aqueous and gaseous analytes
… detect a wide range of analytes including toxic industrial chemicals. For aqueous detection, the newly developed porous glasses successfully immobilized otherwise soluble dyes that could detect changes in solution pH, caused by boronic acid-diol interactions. This allowed for rapid and sensitive …
