Abstract
WE PROPOSE TO DEVELOP A FIBER OPTIC PROBE FOR LITHIUM ION BASED ON NEW FLUORESCENT LITHIUM ION CARRIERS IMMOBILIZED ONFIBER OPTIC BUNDLES BY LANGMUIR-BLODGETT FILM TECHNIQUES. IN PHASE I THE NEW FLUORESCENT IONOPHORE WILL BE SYNTHESIZEDAND TESTED FOR LI/NA SPECIFICITY. OPTICAL PROPERTIES WILL ALSO BE INVESTIGATED TO DETERMINE SUITABILITY FOR USE IN A FIBER OPTIC PROBE. IN PHASE II WE WILL SYNTHESIZE SOME ADDITIONAL ANALOGS OF THE FLUOROPHORES PREPARED IN PHASE I. THOSE HAVING THE BESTSPECIFICITIES AND OPTICAL PROPERTIES FOR LITHIUM WILL BE USED TO PREPARE FIBER OPTIC PROBES. THE PROBES WILL BE USEDTO DEVELOP A METHOD FOR DETERMINATION OF LI(+) ION IN THE BLOOD SERUM OF PATIENTS BEING TREATED WITH LITHIUM FOR MANIC/DEPRESSIVE PSYCHOSIS.
