To study them, scientists have developed “micropatterning” techniques, which involve creating protein patterns to cultivate living cells. But it’s difficult to monitor and regulate the proteins surrounding a cell in vitro, and such techniques are often limited to the use of a single protein.

To make things easier, imaging specialists and cell biologists have developed a device—called PRIMO—that can print complex patterns consisting of multiple proteins in order to cultivate cells and uses a UV illumination system to visualize them.
