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...
In his first experiments, Kistler usedhydrogels, 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 seeps...
The flexible properties of hydrogels — highly absorbent, gelatinous polymers that shrink and expand depending on environmental conditions such as humidity, pH and temperature — have made them ideal for applications from contact lenses to baby diapers and adhesives. In recent years, researchers have...
Hydrogels.Hydrogels are made of a thick gel that delivers intense ingredients. They are suitable for eye masks or other spot treatments because they can improve hydration, especially when combined with a collagen peptide. Read the ingredients.The next step to picking the perfect facial mask is...
The hydrogels containedpolyampholytesor PA gels with structures responding according to external stimuli such as temperature. The structure made an impact on memory and forgetting behavior of the gels based on rapid water uptake then slowly releasing water. ...
Most AI algorithms are inspired by the complex way the human brain works but the researchers say that hydrogels represent a different kind of "intelligence" that could be used to develop new, simpler algorithms. "Ionic hydrogels can achieve the same kind of memory mechanics ...
Polymers with this ability are referred to as hydrogels, superabsorbents, or hydrocolloids. Depending on the degree of cross linking, the strength of the gel network can be varied. This is an important property because gel strength is related to the tendency of the polymer to deform or flow ...
Currently, a vast effort is ongoing toredesign all these tools for biomedical and biotechnological applications.However, recent studies have envisioned the possibility of using CRISPR-Casnucleases in bioengineering of smart materials, for example hydrogels These water-filled polymers are encapsulatedby DNA...
A team of researchers have created a new kind of glue that can bind battery elements together with hydrogels. Hydrogels are water-based materials that aren’t dissimilar to the tissues that make up human muscles and flesh. The battery isn’t stret...
The Bao et al. prosthetic lumbar disc nuclei are made from hydrogels. Hydrogels have been used in biomedical applications, such as contact lenses. Among the advantages of hydrogels is that they are more biocompatible than hydrophobic elastomers and metals. This biocompatibility is largely due to the...
