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.
