NOT A DESSERT GONE WRONG!
So far the nucleic acids used to assemble objects are nano-sized and making them into larger visible object is expensive.
Now researchers have developed a gel-like materials that they could inexpensively extrude from a 3-D printer. Furthermore they showed that human cells could grow in the gels, which is the first step toward the ultimate goal of using the materials as scaffolds for growing tissues.
