Light-activated medical implants: Team develops light-guiding hydrogel for cell-based sensing
A hydrogel that knows when to go (w/ Video)
Rice University bioengineers have created a hydrogel that instantly turns from liquid to semisolid at close to body temperature – and then degrades at precisely the right pace.
Better tissue healing with disappearing hydrogels
When stem cells are used to regenerate bone tissue, many wind up migrating away from the repair site, which disrupts the healing process. But a technique employed by a University of Rochester research team ...
Smart, self-healing hydrogels open new possibilities in medicine, engineering
University of California, San Diego bioengineers have developed a self-healing hydrogel that binds in seconds, as easily as Velcro, and forms a bond strong enough to withstand repeated stretching. The material ...
Tough hydrogel stretches to 21 times its length, recoils, and heals itself
A team of experts in mechanics, materials science, and tissue engineering at Harvard have created an extremely stretchy and tough gel that may pave the way to replacing damaged cartilage in human joints.
Hydrogel remembers its shape
(Phys.org)—A bit reminiscent of the Terminator T-1000, a new material created by Cornell researchers is so soft that it can flow like a liquid and then, strangely, return to its original shape.
Clay may have been birthplace of life, new study suggests
Clay, a seemingly infertile blend of minerals, might have been the birthplace of life on Earth. Or at least of the complex biochemicals that make life possible, Cornell University biological engineers report ...
Pumping iron: A hydrogel actuator with mussel tone
(Phys.org) —Protein from a small, tasty mollusk inspired Michigan Technological University's Bruce P. Lee to invent a new type of hydrogel actuator.
IBM: Our new gel can kill superbugs
Researchers from computer firm IBM say they have invented a new non-toxic gel that can kill deadly drug-resistant bacteria by cutting through the sludge that shelters them and attacking the germ's cell membrane.
Hydrogel improves delivery of anti-cancer drug
The Institute of Bioengineering and Nanotechnology (IBN) and IBM Research (IBM) have developed a new non-toxic hydrogel that is capable of shrinking breast cancer tumors more rapidly than existing therapies. ...
Self-healing hydrogels ease into production
Hydrogels are semi-solid materials formed by polymer chains that trap water molecules into three-dimensional gels. They are used in a variety of applications, including soft contact lenses, but the fragile ...
A glucose meter of a different color provides continuous monitoring
(Phys.org) —University of Illinois engineers are bringing a touch of color to glucose monitoring.
Nanoengineers can print 3D microstructures in mere seconds
(Phys.org)—Nanoengineers at the University of California, San Diego have developed a novel technology that can fabricate, in mere seconds, microscale three dimensional (3D) structures out of soft, biocompatible ...
New light-controlled gel makes big strides in soft robotics (w/ Video)
(Phys.org) —Inspired by the way plants grow toward light sources, a phenomenon known as phototropism, bioengineers from the University of California, Berkeley have created a hydrogel that could be manipulated ...
