Fluorescence Spectrum of Amikacin Sulfate Injection: Research on Its Properties

Objective To investigate the properties of fluorescence spectrum of amikacin sulfate injection. Methods Amikacin sulfate injection was excited by laser and got the fluorescence spectrum.Besides,the lifetime of amikacin sulfate injection was measured and the influence of dexamethasone sodium phosphate on amikacin sulfate injection was studied. Results The fluorescence spectrum of amikacin sulfate injection under different concentration had certain change,low-fluorescence spectral peaks were linearly red-shifted and the fluorescence intensity exponentially increased with the increment of concentration.The content of each fluorescence component was analyzed from the time-resolved fluorescence decay curve.Dexamethasone sodium phosphate had fluorescent quenching effect on amikacin sulfate injection. Conclusions Fluorescence spectroscopy which can determine the concentration of amikacin sulfate injection and the content of each fluorescence component provides effective means to determine some medicines.
