Sequestering ability to Cu2Â + of a new bodipy-based dye and its behavior as in vitro fluorescent sensor

The synthesis of a new Bodipy (4,4-difluoro-4-bora-3a,4a-diaza-s-indacene)-based chemosensor was developed. The sensor shows selective sequestering properties towards Cu2 + at micromolar concentrations. It crosses membrane of erythrocytes, colors them with a red fluorescence and is sensible to Cu2 + variation in cells.179
