Nature extensively exploits high-energy transient self-assembly structures that are able to perform work through a dissipative process. Often, self-assembly relies on the use of molecules as fuel that is consumed to drive thermodynamically unfavourable reactions away from equilibrium. Implementing this kind of non-equilibrium self-assembly process in synthetic systems is bound to profoundly impact the fields of chemistry, materials science and synthetic biology, leading to innovative dissipative structures able to convert and store chemical energy. Yet, despite increasing efforts, the basic principles underlying chemical fuel-driven dissipative self-assembly are often overlooked, generating confusion around the meaning and definition of scientific terms, which does not favour progress in the field. The scope of this Perspective is to bring closer together current experimental approaches and conceptual frameworks. From our analysis it also emerges that chemically fuelled dissipative processes may have played a crucial role in evolutionary processes.

化学燃料驱动的自组装中的能耗

大自然广泛利用了能够通过耗散过程完成工作的高能瞬态自组装结构。通常,自组装依赖于使用分子作为燃料,该分子被消耗以驱使热力学上不利的反应偏离平衡。在合成系统中实施这种非平衡自组装过程必将对化学,材料科学和合成生物学领域产生深远影响,从而导致能够转化和存储化学能的创新型耗散结构。然而,尽管付出了更多的努力,但化学燃料驱动的耗散自组装的基本原理却经常被忽略,围绕科学术语的含义和定义引起混乱,这不利于该领域的进步。该观点的范围是将当前的实验方法和概念框架紧密结合在一起。从我们的分析还可以看出,化学助燃的耗散过程可能在进化过程中发挥了关键作用。
