Hydrogel controls cell growth outside the body

Chemists at Radboud University discovered a unique material in 2013. From a synthetic polymer named polyisocyanopeptide (PIC), they made a gel that behaves similar to the matrix that surrounds the cells in your body. The ...

A shapeshifting material based on inorganic matter

By embedding titanium-based sheets in water, a group led by scientists from the RIKEN Center for Emergent Matter Science has created a material using inorganic materials that can be converted from a hard gel to soft matter ...

Coating plastics with porous nanofilm

Pore size in porous materials affects the property of the material. For example, small pores create more absorbent surface areas. Silica gel, which is often used in food packaging to soak up moisture, is one typical example.

Gel instrumental in 3-D bioprinting biological tissues

The eventual creation of replacement biological parts requires fully three-dimensional capabilities that two-dimensional and three-dimensional thin-film bioprinting cannot supply. Now, using a yield stress gel, Penn State ...

Finding a handle to bag the right proteins

Purifying specific protein molecules from complex mixtures will become easier with a simpler way to detect a molecular tag commonly used as a handle to grab the proteins.

Dehydrating plant proteins at the speed of sound

Almost everyone is familiar with ultrasound—the high-frequency sound waves that bounce around in the body creating echo patterns that allow expectant parents to view their babies in the womb or clinicians to capture images ...

Probing microscopic wiggles in squishy materials

The term "colloidal gel" may not be a household phrase, but examples of these materials are everywhere in our daily lives, from toothpaste and shower gel to mayonnaise and yogurt. Colloidal gels are mixtures of particles ...

Biomimetic hydrogel with photodynamic antimicrobial effect

Infections are a dreaded threat that can have fatal consequences after an operation, in the treatment of wounds, and during tissue engineering. Biomimetic hydrogels with "built-in" antimicrobial properties can significantly ...
