Nanoswimmers target brain tumors and deliver anticancer drugs to them

An international team of researchers has developed miniscule, self-propelled devices that mimic the way cells move. These “nanoswimmers” cross the blood–brain barrier highly efficiently, and could lead to the development of drug delivery systems that navigate through tissues and organs to target specific sites precisely.

…penetrating the blood–brain barrier, which prevents microbes, toxins and large molecules from entering the brain, has proved hugely challenging. One major goal is to develop self-guided polymersomes that traverse this barrier to deliver their cargo to a specific brain area.
