英文摘要	a bodipy(4,4-difluoro-4-bora-3a,4a-diaza-s-indacene)-based fluorometric sensor array has been developed for the highly sensitive detection of eight heavy-metal ions at micromolar concentration. the di-2-picolyamine (dpa) derivatives combine high affinities for a variety of heavy-metal ions with the capacity to perturb the fluorescence properties of bodipy, making them perfectly suitable for the design of fluorometric sensor arrays for heavy-metal ions. 12 cross-reactive bodipy fluorescent indicators provide facile identification of the heavy-metal ions using a standard chemometric approach (hierarchical clustering analysis); no misclassifications were found over 45 trials. clear differentiation among heavy-metal ions as a function of concentration was also achieved, even down to 10(-7) m. a semi-quantitative interpolation of the heavy-metal concentration is obtained by comparing the total euclidean distance of the measurement with a set of known concentrations in the library.
