Figure 3. Characterization of fluorescein-modified nanoceria.

Figure 3

Fluorescein-modified nanoceria nanoparticles were characterized by A) FT-IR and B) UV-VIS and fluorescence spectroscopies. DLS analyses of particle suspension stability with fluorescein-modified and unmodified nanoceria in C) exposure medium (Ex vivo medium + 1%serum) and D) water and PBS. Particle suspensions were characterized at 0, 2, 16, 24 and 48 hours. Error bars and values in parentheses correspond to standard deviation of the measurements.
