Abstract
Intranasal administration is a promising effective and non-invasive drug delivery to the brain without passing through the blood-brain barrier (BBB). Cell penetrating peptide-modified block copolymer micelles (MPEG-PCL-Tat) have potential for improvement of mucosal permeability and nose-to-brain transport efficiency. Here we review the advantages of our MPEG-PCL-Tat micelles for intranasal drug and gene delivery.
