New nanocarrier drug delivery technology crosses the blood-brain barrier
(PHYSorg.com Nanotechnology)

A Japanese research team has developed a cyclic peptide (a chain of amino acids bonded circularly) that enhances blood-brain barrier (BBB) penetration. By attaching the cyclic peptide to the surface of nanoparticles, research and development of new drug nanocarriers for drug delivery to the brain becomes possible.
