Carbon nanotube injectors probe living cells without damage

In order to investigate the processes that go on inside a single human cell–or even specific subcellular compartments–researchers need a device that is small and controlled enough to pass through the delicate cell membrane. Carbon nanotubes (CNTs), with their needle-like geometry, high elasticity and strength, have recently shown that they’re up to the task.
