Oct. 2, 2024 — Researchers have created an array of nanopillars that can breach the nucleus of a cell -- the compartment that houses our DNA -- without damaging the cell's outer membrane.

Illustration of a how a cell's nucleus (green) deforms around the nanopillars and causes its membrane to form temporary breaches, which are self-repairing.
