Scientists use cells to fold origami
Using the tip of glass pointer, scientists are activating these microscopic sheets of plastic to fold into 3 dimensional shapes, a process they call micro-origami. The researchers grew connective tissue cells on the seams of origami designs, allowing them to harness the traction force of the cells to fold the plastic sheets into different shapes. In another experiment, the researchers used rat heart cells to shape these tiny origami structures.
