METHODS AND COMPOSITIONS FOR TARGETING FENESTRATED VASCULATURE

摘要

Targeting of a fenestrated vasculature at a body site by micro or nanoparticles can be increased by using particles that have a radius substantially equal to a critical radius of a normal vasculature at the body site. The particles can be used for treating or monitoring a physiological condition responsible for the fenestrated vasculature. A method of improving an ability of micro or nanoparticles to target fenestrated blood vessels in a body site by selecting particles from a population of the micro or nanoparticles, where the selected particles have a radius that permits enhanced delivery into the fenestrated blood vessels.
