The importance of thermodynamics for molecular systems, and the importance of molecular systems for thermodynamics

Abstract

Improved understanding of molecular systems has only emphasised the sophistication of networks within the cell. Simultaneously, the advance of nucleic acid nanotechnology, a platform within which reactions can be exquisitely controlled, has made the development of artificial architectures and devices possible. Vital to this progress has been a solid foundation in the thermodynamics of molecular systems. In this pedagogical review and perspective, I will discuss how thermodynamics determines both the overall potential of molecular networks, and the minute details of design. I will then argue that, in turn, the need to understand molecular systems is helping to drive the development of theories of thermodynamics at the microscopic scale.
