Abstract
Zinc is an important biogenic element which is able to connect with indicators such as a spiropyran. The spiropyran is known for its fluorescent character and selectivity towards zinc ions (and some other metal ions, e.g. cadmium). This complex, especially with zinc, gives a high fluorescence intensity which was analyzed by fluorescence spectra and by capillary electrophoresis with laser induced fluorescence detection. In addition, the influence of visible light irradiation on zinc release was tested. The spiropyran specificity to zinc was also investigated by coupling with copper and cadmium.
