A biomimetic hybrid nanoplatform for encapsulation and precisely controlled delivery of therasnostic agents

Supplementary Figure 1. Fullerence has poor solubility in water while the C60S and LC60S nanoparticles can be stably dispersed in water. (a) A typical photograph of fullerence (C60), C60S nanoparticles, and LC60S nanoparticles in deionized water (2 mg ml-1). The C60S and LC60S nanoparticles can be well dispersed in deionized water while fullerene forms aggregates and sinks down at the bottom of the cuvette. (b) A typical photograph of the aqueous solutions of C60, C60S nanoparticles, and LC60S nanoparticles after shining a red laser beam (arrow) through them in dark. As a result of the Tyndall effect (i.e., scattering of laser beam by nanoparticles in solution), a light track (indicated by asterisks) is visible in dark in the solutions of C60S and LC60S nanoparticles. This indicates both the C60S and LC60S nanoparticles can be stably dispersed in deionized water while the aqueous solubility of C60 is negligible.
