Abstract

Fullerene C70 has been solubilized in aqueous solutions using phenol gallic acid. The supermolecule of C70-gallic acid is hypothesized to be assembled via pi-stacking as well as by caging of gallic acid around single or multiple C70. When excited with light, C 70-gallic acid exhibited two prominent fluorescence peaks at 540 nm and 719 nm. Using confocal fluorescence microscopy we have observed the translocation of C70-gallic acid and their consequent green fluorescence in CHO cells, oyster tissue, and living organism Ceriodaphnia. The resistance of C70-gallic acid to photobleaching combined with the antioxidation property of gallic acid can potentially be utilized for novel biological imaging, sensing, and drug delivery.
