Glowing 4D-printed flowers could pave way for replacement organs
It is based on a variety of materials to create a solid 4D printing and folding of printed objects. But Harvard's Jennifer Lewis and her colleagues wanted to simplify the process. "Our goal is to take a page from that of nature such as flowers to see the shape of complex changes," she said.
In particular, the team would like to emulate the plant cell line consists of a limited range of activities to cellulose fibers. They mixed the cellulose fibers from the wood pulp and acrylamide hydrogel when immersed in water, swelling of mucus. When extruded through a nozzle printer 3D, these fibers means that the print queue gel only grew longer blocked.
By itself, this is somewhat limited, but the team has also developed a mathematical model for the type of shape design criss-cross of the curve is used to align the fibers to ensure that the exact method, the team hopes curved shape. "It depends on how we print, we can actually encode bending and twisting cruiser," Lewis said.
To determine this, the print surface of a flower with the same characteristics. But when exposed to water coil in five different directions. They also copied the design of orchids and became very close to the real thing when bent and curls (see above) shaped plane's extra gel fluorescent dye made it easy to see the flowers and make it glow. light, pleasant
Now the team is exploring the potential use of technologies, including tissue engineering could eventually grow new organs. "Now, most of the tissue in two ways. The most active of these cells in three dimensions, "Lewis said. Future of damaged tissue can be printed as flat and put themselves into the desired shape, she said.
