We discussed the synthesis of individual graphitic nanocups using a series of techniques including chemical vapor deposition, acid oxidation and probe-tip sonication. By citrate reduction of HAuCl4, the graphitic nanocups were effectively corked with gold nanoparticles due to the chemically reactive edges of the cups.

Exosome application is an emerging tool for drug development and regenerative medicine. We establish an exosome isolation protocol with high purity to isolate exosomes from novel identified stem cells called CB-SC for mechanistic studies. We also coculture CB-SC-derived exosomes with human monocytes, leading to their differentiation into phenotypically distinct macrophages.
