Diagnosis of some diseases related to the histidine level in human serum by using the nano optical sensor Eu-Norfloxacine complex

A low cost, selective and sensitive method was developed for diagnosis of some diseases such as Histidinemia, Alzheimer, Rheumatoid arthritis, and inflammation in obese women. This method depends on the assessment of the histidine in blood serum samples of different diseases. The assessment of the histidine was based upon measuring the luminescence intensity of the nano Eu-Norfloxacine complex doped in sol-gel matrix optical sensor at 617 nm in acetonitrile at (pH 7.6, (ex = 380 nm) in the presence of different concentrations of histidine.
