Living cells are encapsulated in a substrate like a hydrogel to make a bioink, which is then printed in layers using a specialized printer.

To better care for delicate marine artifacts, researchers in ACS Sustainable Chemistry & Engineering developed a new hydrogel that quickly neutralizes harmful acids and stabilized waterlogged wood from an 800-year-old shipwreck.

In an advance that could prevent that kind of device failure, MIT engineers have found a simple and general way to eliminate fibrosis by coating devices with a hydrogel adhesive.

This theory tells that microscopic interactions between ions and polyacrylic acid can make hydrogel swell when the released ions inside the hydrogel are unevenly spread out.

The researchers showed that they could package the yeast inside hydrogel capsules to create a filter that removes lead from water.
