Researchers at Northwestern University have been inspired by "Laminin," and invented a hydrogel "Band-Aid" that can help wounds heal quickly. This new research achievement was published in the "Journal of the National Academy of Sciences". The researchers said that laminin is a protein found in human tissues such as the skin that can send signals to cells to promote differentiation and adhesion.

On June 5, 2018, engineers at RutgersUniversitycreated a smart gel that uses 3D printing to walk underwater. This smart gel can create soft robots that, like octopuses, can walk under water and will not damage them even if they touch something. This smart gel can also produce human tissues such as artificial heart, stomach, and muscle. In addition, it can also diagnose diseases, detect and transport drugs, or equipment for performing underwater examinations

Intelligent wound dressing" can release the drug automatically. If the drug is about to be released, it can light up the alarm.The new dressing can stretch with the body, but also respond to changes in skin temperature

The hydrogel facial mask is similar to the biological fiber facial mask in that it is skin-friendly and the mask fluid does not flow out; the difference is that the hydrogel facial mask is not breathable, but it makes it more moisturizing, more tender and more like texture. jelly

Recently, the British journal Nature Communication published a new achievement Using mouse models, scientists in the UShave successfully displayed a drug release gel. This gel can respond to disease activity and can load different small molecules. It can "smart" release the corresponding dose according to the different severity of the disease. This will open a new treatment for the future

According to the papers published in Advanced Healthcare Materials magazine,The team's approach is to strongly glue a layer of hydrogel, a soft, smooth polymer made of water, to common soft materials, such as latex, rubber, and silica gel. After bonding, we get soft, stretchable, smooth, and no leakage of viruses and other small molecules, "hydrogel stack".
