Norfloxacin Fluorescent Probe for the Assessment of Cefepime in Biological Fluids and Pharmaceutical Formulation; Investigation of the Greenness and Blueness Characteristics.

In the present study, a norfloxacin (NFX) fluorescent probe was tailored for the spectrofluorometric measurement of cefepime (CFP). The proposed approach measured the quenching effect of CFP on the fluorescence intensity of NFX in acetate buffer solution. The obtained results show that CFP strongly quenches the fluorescence of NFX in a static mechanism.
