Abstract
The interactions of norfloxacin (NFA), DNA, and Cu2+ are studied by fluorescence and UV-spectra method. According to the experimental results, it can be concluded that NFA can form a steady binary complex with Cu2+. There is a linear relationship between the Fluorescence intensity of the norfloxacin–Cu2+–DNA system and the concentration of DNA. And when the concentration of the NFA is 1.95×10−5 mol L−1, they possess a good linearity in the concentration of DNA ranged from 4.7×10−6 to 2.8×10−5 mol L−1.It is a good method due to the high sensitivity and selectivity.
