Natural Polymeric Nanoparticles for Brain-Targeting: Implications on Drug and Gene Delivery.

There is a broad range of biological, chemical and physical hurdles for drugs to reach the brain. Nanoparticulate drug delivery systems hold tremendous potential for diagnosis and treatment of brain disorders, including the capacity of crossing the blood-brain barrier and accessing to the brain after systemic administration. Thus, nanoparticles enable the delivery of a great variety of drugs including anticancer drugs, analgesics, anti- Alzheimer`s drugs, protease inhibitors, and several macromolecules into the brain.
