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

A novel class of programmable, self-healing hydrogel nanocomposites has been developed by combining cellulose nanocrystals ...

The dura mater is a fibrous membrane of connective tissue that covers the spinal cord and the brain. Many neurosurgeries that involve access to the underlying nervous tissues create defects in the ...

Hydrogels are soft, water-rich polymeric materials that can swell or shrink in response to environmental stimuli. This ability to change shape makes them valuable in miniaturized devices for flexible ...

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 ...

Hydrogels—soft, water-rich polymer networks—have evolved far beyond their early biomedical uses. By integrating dynamic ...

Natural biomass hydrogels are emerging as promising building blocks for intelligent sensors because they combine softness, water-rich structures, tunable networks, and abundant functional groups. A ...

Periodontitis is one of the most common chronic inflammatory diseases worldwide and a leading cause of tooth loss in adults.

(Nanowerk Spotlight) Imagine a material that doesn’t just respond to one stimulus, like heat or light, but can sense multiple environmental triggers and adjust its behavior accordingly. Picture this ...
