Results
Because of their high surface area and the hydrophobicity, mesoporous carbon nanoparticles (MCN) were successfully synthesized and utilized as a potential drug nanocarrier. In addition, a phospholipid layer was applied as a gate-keeper to control the load/release behavior of drugs. The MCN/phospholipid core/shell structure here provides a new alternative for next-generation bio-medical applications.
The research was supported by the National Taiwan University.
