| 摘要 |
The present invention makes use of a unique methodology of double nano- encapsulation for protecting and controlling the release of active agents, either hydrophobic or hydrophilic, from stable nanoparticles of opposite characteristics. The protection of the active agent was achieved by loading the agent to be protected, into nanocarriers, which were subsequently encapsulated into sub-micron nanoparticles. The sub-micron nanoparticles formation has been successfully achieved by the use of novel nano spray techniques. |
