The future of cell-free biotechnology

Michael Jewett is a pioneer of cell-free biotechnology. Instead of using living microbes as factories, he uses their internal molecular machinery to make valuable proteins, medicines, diagnostics, and other chemicals. Jewett recently used the technique for vaccine production in an approach that could produce up to 150,000 doses from one liter. He believes cell-free biotech could democratize the production of essential medicines, improve water safety, and help convert atmospheric carbon into useful products, among other promising possibilities. “It’s just-add-water biotechnology,” Jewett tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.
