Jelly invention can heal itself like human skin

Scientists from The Australian National University (ANU) have invented a new jelly material that mimics biological matter such as skin, ligaments and bone, and which is very strong, self-healing and able to change shape.

Research team creates hydrogel adhesives to seal wounds

A Band-Aid adhesive bandage is an effective way to stop bleeding from skin wounds, but an equally viable option for internal bleeding does not yet exist. Surgical glues are often used inside the body instead of traditional ...

Could we build a Blade Runner-style 'replicant'?

The new Blade Runner sequel will return us to a world where sophisticated androids made with organic body parts can match the strength and emotions of their human creators. As someone who builds biologically inspired robots, ...

New superglue allows for bonding stretchable hydrogels

(Phys.org)—A team of researchers at Johannes Kepler University Linz has developed a new type of glue that can be used to bond hydrogels to other hard or soft objects. In their paper published on the open-access site Science ...

New process makes hydrogels useful for more applications

Hydrogels are gelatinous amalgams of cross-linked polymers that can absorb and hold large quantities of water. Their uses vary widely. Certain hydrogels form the absorbent layer in disposable diapers, while others form the ...

Shape-shifting gels get smarter

Gels are useful: we shave, brush our teeth, and fix our hair with them; in the form of soft contact lenses they can even improve our eyesight.

Researchers identify movement of droplets on soft surfaces

Researchers from the University of Twente have succeeded in clearly identifying why droplets on soft, squishy surfaces react differently than on hard surfaces. A water droplet, for example, moves very differently over jelly ...

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 to pass through ...

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 nature of the materials ...
