Executive Summary. 1  The bloodâbrain barrier (BBB) is a significant obstacle to therapeutic delivery for CNS disorders. Among various strategies, nanobiotechnology plays an important role in facilitating drug delivery across the BBB. 2  Desirable characteristics of the ideal method of therapeutic delivery across the BBB are described in this article.
The function of the blood-brain barrier is to allow water, lipid  soluble molecules, and gases into the brain extracellular fluid.  The barrier also lets in molecules that a â¦ re necessary for neural  function such as amino acids and glucose.Stax de Morgan.o put it simply, the main function of a Barrier Island is to protect the coastline, meaning that it serves as a shield for the coast, taking all the damage from the shifting â¦ tides and waves, and the violent waves that would bring severe damage to beaches.
