Fluorescent microsphere fiber optic microsensor array for direct iodide detection at low picomolar concentrations
Katarzyna Wygladacz and Eric Bakker
Fluorescent optode microspheres doped with the halide-selective receptor [9]mercuracarborand-3 and a lipophilic pH fluoroionophore were found to exhibit picomolar limits of detection to iodide at pH 3.5, and were used to monitor the precipitation of iodide by silver ions at subnanomolar concentrations, just above their calculated solubility.
