A revolutionary paradigm in chemistry and materials science research: self-driving laboratories

A self-driving laboratory (SDL), an automated experimental platform that integrates machine learning algorithms and robotics, has the potential to revolutionize traditional research methods and accelerate progress in chemistry and materials science. However, despite its significant potential, the development and practical application of SDLs have not yet met expectations. To date, only a limited number of SDLs have been successfully constructed and applied in research, mainly due to the challenges involved in fostering interdisciplinary collaboration and achieving high levels of system integration. In this review, we present a comprehensive overview of recent SDL applications in chemistry and materials science. Firstly, SDLs used for reaction optimization are discussed, including the refinement of photocatalytic reaction conditions and the exploration of Pareto Frontiers in homogeneous catalysis. Next, their role in materials synthesis is examined, focusing on the production of optical materials and catalytic materials. Additionally, SDLs' application in mechanistic investigation is introduced, such as the identification and study of molecular electrochemical mechanisms. Finally, we highlight the key challenges that must be considered and overcome to facilitate the advancement and wider implementation of SDLs.
