What to know about DNA origami nanosyringe actively transports molecules into synthetic cells

Researchers at the University of Stuttgart have developed a programmable DNA origami nanosyringe capable of transporting molecular cargo into synthetic cells via mechanical penetration. The device uses DNA strand-displacement reactions to penetrate and retract from lipid membranes, allowing for the controlled initiation of biochemical processes.

What happened

DNA origami nanosyringe actively transports molecules into synthetic cells Lisa Lock Scientific Editor Robert Egan Senior Editor Transporting molecules across biological membranes is essential for life.

Why it matters

In nature, this can occur through passive transport, known as diffusion.

Common ground

"Biological systems often use mechanical motion to accomplish tasks that cannot be achieved by diffusion alone," says Professor Laura Na Liu, director of the 2nd Physics Institute at the University of Stuttgart.

Perspective signals
