Stretchable, biocompatible hydrogels with complex patterning for tissue engineering
Researchers have developed a new way of making tough—but soft and wet—biocompatible materials, called "hydrogels," into complex and intricately patterned shapes. The process might lead to injectable materials ...
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 ...
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.
Light-activated medical implants: Team develops light-guiding hydrogel for cell-based sensing
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.
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.
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 ...
Chemists characterize 3-D macroporous hydrogels
Carnegie Mellon University chemists have developed two novel methods to characterize 3-dimensional macroporous hydrogels—materials that hold great promise for developing "smart" responsive materials that ...
A practical gel that simply 'clicks' for biomedical applications
If you opt to wear soft contact lenses, chances are you are using hydrogels on a daily basis. Made up of polymer chains that are able to absorb water, hydrogels used in contacts are flexible and allow oxygen ...
Researchers introduce improved injectable scaffold to promote healing
Rice University scientists have found the balance necessary to aid healing with high-tech hydrogel.
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.
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.
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 ...
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. ...
