Controlled Release from Porous Platforms
The authors present a method for controlling the release of therapeutics by applying a plasma polymer layer to the surface of porous materials.

Conclusion

The authors described a method for controlled release of therapeutics from porous materials that has the potential to be applied to various therapeutics and types of porous materials. The method involves the application of a plasma-polymer layer on top of porous materials, and the thickness of this layer controls release kinetics. Athough the current study emphasizes plasma polymerization as a tool to reduce pore diameter at the surface, future work should consider the influence of the plasma polymer's physical properties, such as hydrophilicity, on drug release. The ability of plasma polymerization to provide films of various physical and chemical properties provides enormous flexibility for fine tuning drug-release platforms to suit various drugs and applications.
