...The “engineered living material” our team has been working on contains programmed bacteria embedded in a soft hydrogel material. We first published a paper in Nature Communications showing the potential effectiveness of this material in August 2023.
The hydrogel that forms the base of the material has similar properties to Jell-O — it’s soft and made mostly of water. Our particular hydrogel is made from a natural and biodegradable seaweed-based polymer called alginate, an ingredient common in some foods.
The alginate hydrogel provides solid physical support for bacterial cells, similar to how tissues support cells in the human body. We intentionally chose this material so that the bacteria we embedded could grow and flourish...READ MORE FROM INVERSE
