Synthetic DNA to Become “Ink” for 3D Printed Nanoscale Structures in Medical and Scientific Applications

We’ve heard about filament to produce our common and not so common 3D printed objects and devices. We’ve also heard about the medical advances that 3D printing facilitates, such as the use of nylon polymer in customized surgical 3D printed implants. Well, science and medical research has taken another large leap toward something virtually unimaginable, yet, closer than it may seem: 3D printing using synthetic DNA. Today, MIT News reports that researchers have come a step closer to replicating DNA structures that can then be used in 3D design and printing — “Where the ink is synthetic DNA.”

Complex 3-D DNA structures

MIT biological engineers have created a new computer model that allows them to design the most complex three-dimensional DNA shapes ever produced, including rings, bowls, and geometric structures such as icosahedrons that resemble viral particles. (Learn more:
