A facile approach for the delivery of inorganic nanoparticles into the brain by passing through the blood-brain barrier (BBB)

This study provides an easy and simple method to obtain inorganic nanoparticles that can penetrate the blood–brain barrier, the heavily guarded system in the brain, via cross-linked serum albumin surface coatings. Their intact BBB permeability was confirmed in both in vitro and in vivo tests.
