Dutch researchers create microscopic pyramids to cage living cells

A team at the University of Twente in the Netherlands has managed to create a tiny pyramid small enough to house a single living cell. The pyramids were developed using a new 3D micro and nanofabrication technology called "corner lithography," and they allow researchers to better view cells as they would normally behave in a three-dimensional environment — an improvement over the 2D view offered by a petri dish. Because of the pyramid's open sides, two cells close enough together will sti...
