Synthetic biology provides scientists with an arsenal of new tools to accurately and efficiently modify the molecular workings of cells to gain medical advantages. According to Jim Collins, Termeer Professor of Medical Engineering and Science at Massachusetts Institute of Technology in Cambridge, “Synthetic biology brings together engineering and molecular biology to model, design, and build synthetic gene circuits and other biomolecular components and uses them to rewire and reprogram organisms for a variety of purposes.” The clinical uses of synthetic biology already cover a wide range of areas, including diagnostics and treatments. Further, these clinical applications will likely expand more rapidly over the next few years because of the easy-to-use gene editing tools now available.
