Solid state nanopores are single-molecular devices governed by nanoscale physics with a broad potential for technological applications. However, the control of translocation speed in these systems is still limited. Ionic liquids are molten salts which are commonly used as alternate solvents enabling the regulation of the chemical and physical interactions on solid–liquid interfaces. While their combination can be challenging to the understanding of nanoscopic processes, there has been limited attempts on bringing these two together. While summarizing the state of the art and open questions in these fields, several major advances are presented with a perspective on the next steps in the investigations of ionic-liquid filled nanopores, both from a theoretical and experimental standpoint. By analogy to aqueous solutions, it is argued that ionic liquids and nanopores can be combined to provide new nanofluidic functionalities, as well as to help resolve some of the pertinent problems in understanding transport phenomena in confined ionic liquids and providing better control of the speed of translocating analytes.

从水溶液到具有固态纳米孔的离子液体作为研究运输和易位现象的视角

固态纳米孔是受纳米物理学控制的单分子器件，具有广泛的技术应用潜力。然而，这些系统中易位速度的控制仍然有限。离子液体是熔融盐，通常用作替代溶剂，能够调节固液界面上的化学和物理相互作用。虽然它们的组合对理解纳米级过程可能具有挑战性，但将这两者结合在一起的尝试有限。在总结这些领域的最新技术和开放性问题的同时，从理论和实验的角度，提出了几项重大进展，并展望了离子液体填充纳米孔研究的下一步。与水溶液类比，
