  • Title: Nanotechnology approaches for drug and small molecule delivery across the blood brain barrier.
    Author: Silva GA.
    Journal: Surg Neurol; 2007 Feb; 67(2):113-6. PubMed ID: 17254859.
    Abstract:
    Nanotechnology involves the design, synthesis, and characterization of materials and devices that have a functional organization in at least one dimension on the nanometer (ie, one billionth of a meter) scale. One area in which nanotechnology may have a significant clinical impact in neuroscience is the selective transport and delivery of drugs and other small molecules across the blood brain barrier that cannot cross otherwise. Using a variety of nanoparticles composed of different chemical compositions, different groups are exploring proof-of-concept approaches for the delivery of different antineoplastic drugs, oligonucleotides, genes, and magnetic resonance imaging contrast agents. This review discusses some of the main technical challenges associated with the development of nanotechnologies for delivery across the blood brain barrier and summarizes ongoing work.
