New Virus inspired technique to deliver drugs to brain

Date: 13 October 2019 Tags: Biotechnology


Researchers have engineered small particles, similar to the size of viruses, to cross the protective border and reach the brain.


The research is path-breaking because a protective layer protects circulating blood from brain. The new particle could be used to deliver drugs to the brain more effectively in the future.



  • The new method allowed for combination drug delivery through intravenous injection to cross the blood-brain barrier (BBB).

  • To make it possible, the scientists modified components from a virus that targets the brain called bacteriophage fd to deliver drugs across the BBB.


  • Crossing the blood-brain-barrier has hindered the industry from effectively addressing central nervous system diseases, including brain tumours, and many neurological diseases like Parkinson's, Alzheimer's and Huntington's.

But now since a new way has been discovered, there are more chances of having drugs that can treat these brain affecting neurodegenerative diseases.
