Hydrogels 'Mimic Biological Functions' Professor Jian Ping Gong said, 'Hydrogels are excellent candidates to mimic biological functions because they are soft and wet like human tissues. We are excited to demonstrate how hydrogels can mimic some of the memory functions of brain tissue.'...
Instead of starting with metal, plastic, or ceramic, a 3-D printer for organs and tissues uses bioink: a printable material that contains living cells.The bulk of many bioinks are water-rich molecules called hydrogels. Mixed into...
"What we have done in our work is maintained all the good things about a hydrogel but then made it more porous. Instead of it being one homogenous gel, we are making lots and lots of tiny microgels. "Each individual microgel retains all the good properties of hydrogels but the additional ...
An interesting class of biomaterials employed in different type of drug delivery systems is that of hydrogels. These materials are a unique class of three dimensional cross-linked polymeric networks of physically or/and chemically cross-linked polymers which can imbibe and retain a large amount of ...
Hydrogels are water-soluble cross-linked polymeric networks formed by physical or chemical cross-linking of soluble polymers [184]. Figure 15. Chemical structure of alginate and respective monomers. Several studies have shown that alginate plays an important role in preventing infection in wound ...

In his first experiments, Kistler used hydrogels, which contained water. When drying, these gels behave much as Jell-O does. They break down into a gooey, messy blob because the liquid in the hydrogel evaporates too quickly for the substance to retain its shape. With each molecule that ...
Soft lenses are made of hydrogels, which are plastics that incorporate water into their design for added hydration. In recent years, more soft contact lenses have been made from silicone hydrogels. Silicone hydrogel lenses allow even more oxygen through to the eye than “regular” hydrogels, ...
The researchers’ technique involved cutting an elastomer and four distincthydrogelsinto extremely thin slices. The fragile and transparent hydrogels were useful as a stand-in for glass and brittle plastics to help understand how cracks originate in these materials. They were also easy to measure and...
