Scientists at University College London (UCL) and Nanion Technologies in Munich have developed synthetic DNA-based pores that control which molecules can pass through a cell’s wall, achieving more precise drug delivery.

Therapeutics, including anti-cancer drugs, are ferried around the body in nanoscale carriers called vesicles, targeted to different tissues using biological markers. The new DNA-based pore design is intended to improve that process.
