Hydrogels

Some vaccines aren't very effective, which is due at least partially to the amount of time that they're active within the body. A new injectable hydrogel, however, could allow them to act for a longer period of time, making them more potent.

Heart attacks are a leading cause of death, largely because damage caused by one can lead to more. Now researchers at Rice University have developed a new way to repair heart tissue and reduce scarring, by implanting capsules loaded with stem cells.

Scientists working towards next-generation treatments for blindness have made an exciting breakthrough, demonstrating how a new method of injecting healthy cells into the eyes could act as a one-two punch to address vision loss.

Our brains not only memorize things, they also forget them. While that may seem like a limitation, it's a quality that's been copied in a new hydrogel – and it may actually have some practical applications.

Cartilage plays a crucial role in your knees, but unfortunately once it’s damaged or worn out it’s hard to repair. Now, researchers at Duke University have created a new hydrogel that’s strong enough to withstand forces as well as natural cartilage.

Rupturing tendons or ligaments like an anterior cruciate ligament in the knees can mean long stints on the sidelines, but a new type of synthetic material promises to help things along by acting as a scaffold to accelerate the regeneration of tissue.

Bacteria that produce their own electricity could be useful in batteries, but so far, attempts have been inefficient. A new “biohybrid” system is built around a hydrogel and can support the microbes while effectively collecting their energy.

In search of advanced medical devices that can be ingested by the human body and don’t need to be surgically removed after, scientists at MIT have developed a new technology that would instead break them down by exposure to certain kinds of light.

Medicine, soft robotics and wearable electronics are just a few of the fields that could benefit from a new hydrogel that's applied to the body. The transparent material can sense when it's being touched, bent, heated, or otherwise manipulated.

Scientists in Australia have made a big breakthrough in regenerative medicine, developing a hydrogel that acts as a “sanctuary” for transplanted stem cells in the brain, giving them the smooth start they need to survive in their new environment.

Scientists in Australia have developed a jelly-like material with many of the properties of living tissue. A form of a hydrogel, it is self-healing, very strong and can change its shape – allowing it to mimic skin, ligaments, and bone.

Hokkaido University’s ongoing research into hydrogels has borne fresh fruit: a new polymer-based material that, unlike other polymers, hardens when heated – by 1,800 times.
