(a) Merged image of the transmission and fluorescence images obtained by confocal microscopy of HeLa cell loaded with RBITC labeled Pt NFs at a concentration of Pt of 5 × 10−4 mol L−1, incubated for 6 h; (b,c) The Fluorescence Lifetime Imaging Microscopy (FLIM) imaging of cervical cancer cells (HeLa) incubated with RBITC labeled Pt NFs and free RBITC respectively, fluorescence lifetime is showed in the nanosecond range; (d) Fluorescence decay curves (mean lifetime curve) of the free RBITC (black) and of the RBITC labeled Pt NFs (red) after an excitation at 550 nm.
