[ad_1] The team described the “magnetically steerable, hydrogel-coated robotic thread” in a paper published in Science Robotics. The core of the thread is made from nickel-titanium alloy, which is both bendy and springy. It’s coated with a rubbery paste, or ink, which is embedded with magnetic particles. That’s then covered with a hydrogel, which makes […]

Scientists bioprint living tissue in a matter of seconds
[ad_1] The approach, volumetric bioprinting, forms tissue by projecting a laser down a spinning tube containing hydrogel full of stem cells. You can shape the resulting tissue simply by focusing the laser’s energy on specific locations to solidify them, creating a useful 3D shape within seconds. After that, it’s a matter of introducing endothelial cells […]
Bioengineers 3D print complex vascular networks
[ad_1] For decades, one of the challenges in replicating human tissues has been figuring out a way to get nutrients and oxygen into the tissue and how to remove waste. Our bodies use vascular networks to do this, but it’s been hard to recreate those in soft, artificial materials. This new tool overcomes those challenges […]
Self-healing 3D-printed gel has a future in robots and medicine
[ad_1] The 3D-printed hydrogel is a dual polymer that’s capable of bending, twisting or sticking together when treated with certain chemicals. One polymer has covalent bonds, which provide strength and structural integrity. The other polymer has ionic bonds, which allow more dynamic behaviors like bending and self-adhesion. Together, the polymers create a material that is […]
