The invention relates to devices comprising a sensor layer capable of binding magnesium ions and a scavenging layer that preferentially binds to calcium ions in the presence of both magnesium ions and calcium ions. The sensor layers can comprise known or novel luminionophores. The invention further relates to methods of selectively detecting magnesium ion concentration in the presence of calcium ions.
