Drug-delivering particles aim to breach the blood–brain barrier

TL;DR - Nature surveys emerging drug-delivery particles designed to cross the blood–brain barrier, a longstanding obstacle in treating brain cancers and neurodegenerative diseases.

• Nanoparticle- and exosome-based techniques are competing as potential delivery platforms.
• The approaches aim to transport therapeutics into brain tissue despite the barrier’s restrictive biology.
• The provided excerpt describes the field and its clinical motivation but reports no specific experimental results.
