Sensitive and selective time-gated luminescence detection of hydroxyl radical in water.
A terbium probe for the selective time-gated detection of hydroxyl radical is presented. This probe demonstrates high sensitivity with an 11.0-fold increase in time-gated luminescence intensity for an hour-long exposure to hydroxyl radical concentration in the femtomolar range, and high selectivity for HO* over other reactive oxygen species.
