Award-winning publication: Synchronous long-term oscillations in a synthetic gene circuit

Published in: Nature


Laurent Potvin-Trottier and his team are focused on synthetic biology: an emerging field that aims to engineer biology for practical purposes. Relying on the theory of stochastic processes that considers the limited number of molecules (RNA, proteins) in cells, the researchers have developed a synthetic circuit whose precision rivals that of natural circuits. In the long term, the capacity to create ultra-precise synthetic circuits will make it possible to use synthetic biology in a range of biomedical applications. A promising direction is to design bacteria that produce pharmaceutical components and introduce them into the digestive system for direct drug delivery, so the patient avoids having to take several doses per day.
