Communication
Non-fluorescent nanoparticles resulting from the self-assembly of a new perylene diimide behave as fluorogenic probes for biological cells under physiological conditions giving a dosage-dependent green or red fluorescence and showing very low cytotoxicity. The emission colour can be tuned by photo-irradiation to achieve multicolour labelling.
