In this work, an injectable, tissue-adhesive and low- swelling hydrogel sealant was developed based on o-phthalaldehyde (OPA)/amine chemistry for dural sealing and repairing. The hydrogel was ...

D-printed hydrogel is soft, and sometimes it can be tough. However, could it be hard? Here, researchers from Zhejiang ...

The skin is the largest organ in the human body. It makes up about 15% of our body weight and protects us from pathogens, ...

As helpful as they are to many, fillings and dental implants can be detrimental, and while they have long been the only solutions to decay, it may soon be possible for teeth to regrow themselves. A ...

Growing cells in the laboratory is an art that humans have mastered decades ago. Recreating entire three-dimensional tissues is much more challenging. Researchers are developing a new hydrogel-based ...

First, they submerged the samples in a hydrogel solution containing small compounds that behave as liquid until they link up into polymer chains that absorb water and congeal into a gel. These ...

When skin becomes damaged—from things like wounds, burns, or diseases—it can be very dangerous. But researchers in ...

Empa researchers have developed a printable, non-swelling hydrogel made from cold-water fish gelatin, enabling the creation of 3D living skin mod ...

The basis: gelatin from the skin of cold-water fish. The research has been published in Materials Today Bio ("Mechanically robust non-swelling cold water fish gelatin hydrogels for 3D bioprinting").
