Researchers have created a new bioink that allows them to print catalytically active live cells into various self-supporting 3D geometries with fine filament thickness, tunable cell densities and high catalytic productivity. A research team from the U.S. Department of Energy’s Lawrence Livermore National Laboratory (LLNL) was able to use the new ink to 3D print live cells that are able to convert glucose to ethanol and carbon dioxide gas (CO₂), which increases catalytic efficiency. “This is the first demonstration for 3D printing immobilized live cells to create chemical reactors,” engineer Eric Duoss, a co-author on the paper, said in a statement. “This approach promises to make ethanol production faster, cheaper, cleaner and more efficient. Now we are extending the concept by exploring other reactions, including combining printed microbes with more traditional chemical reactors to create ‘hybrid’ or ‘tandem’ systems that unlock new possibilities.” In the study, the researchers freeze-dried […]
