The usual way to get biological tissues and materials like gels and metals to stick together is using sutures, adhesives or both. Although this generally works, it’s far from ideal, with adhesives ...

(a) Hydrogel sealant is fabricated by simply mixing gelatin with o-phthalaldehyde terminated four-arm poly(ethylene glycol) (4aPEG-OPA). (b) Mechanisms of ...

Scientists use the adhesive capabilities of mussels as a model for simultaneously optimizing the strength, stretchiness and adhesion of GelMA hydrogels, a feat not obtained in previous attempts.

Researchers have developed a hydrogel composed of poly(N-acryloylglycinamide) (PNAGAm) grafted with arginine (R)–glycine (G)–aspartic acid (D)–serine (S) peptide whose elastic modulus can be changed ...

Nearly 20% of cardiac surgery patients will require another operation at some point in the future. This is especially true for younger patients who may need multiple surgeries over several years as ...

Following surgery within the abdominal or pelvic cavities, scar tissue often forms on the inner linings of these cavities and may adhere to the organs which are found within them. This adhesion occurs ...

Researchers have developed an injectable hydrogel which effectively prevents post-surgical scar tissue adhesions in the abdominal and pelvic cavities. Following surgery within the abdominal or pelvic ...

After open-heart surgery has been performed, the scar tissue that forms on the heart will sometimes stick to the tissue surrounding it. Such complications are known as adhesions, and a new hydrogel ...

This illustration highlights how two hydrogels (shown in blue) can be bonded in different ways by thin chitosan films (shown in orange). The bonds that form are extraordinarily strong and can resist ...

(Nanowerk News) One of the primary goals in the field of tissue engineering and regenerative medicine is the development of artificial scaffolds that can serve as substitutes for damaged tissue. These ...
