Scientists Create First Programmable Artificial Cells. You Won't Believe How

Описание: Scientists Create First Programmable Artificial Cells — A Leap Toward Smart Medicine

In a breakthrough that could transform medicine and materials science, researchers at the University of North Carolina-Chapel Hill have created the first artificial cells with programmable DNA and functional cytoskeletons. Led by Dr. Ronit Freeman, the team engineered these cells using a novel “programmable peptide-DNA” technology, allowing them to mimic key features of living cells — including shape, structure, and responsiveness to the environment.

Unlike natural cells that rely on complex proteins, these synthetic versions are built using reprogrammed DNA and peptides. Remarkably, the cells remain stable even in extreme heat (up to 122°F), making them suitable for harsh environments. Their structure can be adjusted for specific tasks, such as drug delivery, diagnostics, or forming responsive fabrics.

“These materials are made to perform a task and then adapt,” said Freeman. By bypassing biology’s limits, scientists can now create customizable cells for regenerative medicine, smart sensors, and more. This work, published in *Nature Chemistry*, not only sheds light on what defines life but also opens a path to materials that may one day surpass nature itself.

This innovation marks a significant step in synthetic biology, offering a glimpse into a future where life is not just studied — but designed.
