A sensor for determining the concentration of a target ion in a liquid sample having a particulate silica doped with: an ionophore capable of binding the target ion; and an indicator capable of producing a detectable signal in response to binding by the ionophore of the target ion. The detectable signal is related to the target ion concentration in the liquid sample.
polymer containing AU-1 was prepared via a simple one-step homogeneous polymerization method. It exhibited mechanical properties suitable for the fabrication of plasticizer-free ion-selective membrane electrodes and bulkoptode films by solvent-casting and spin-coating techniques, respectively. The segmented sandwich membrane technique was utilized to assess the binding constant of free and covalently
