“…For the single‐layer system, the nanochannel is a pore opened up on one layer of graphene sheet 123. Theoretical simulations and experiments have revealed interesting mass transport phenomena across the nanopores and their great potential for desalination,124 DNA sequencing,125 and separation applications 126. Nevertheless, it is rather challenging to fabricate highly reliable devices.…”

From a materials science point of view, graphene is essentially a polymer having a giant, two-dimensional molecular configuration. In this Progress Report, solvated graphene and its derivatives are illustrated from the perspective of soft matter. Firstly, the key appealing features of graphene as a molecular building block for assembling bulk soft materials are highlighed. It is then demonstrated how the intersheet interactions in solution are correlated with the molecular structure of graphene, and how a combination of the unique molecular structure and colloidal interactions can lead to simple, solution-phase approaches for assembling graphenes into a variety of macroscopic nanoarchitectures. A number of new exciting functions and applications are also highlighted, which are enabled by the solvation effect and in particular, it is discussed why and how solvated graphenes can offer exciting functions that are unattainable with the dried, hard counterpart. The discussion is concluded with some personal perspectives on the future directions in which this emerging class of functional soft materials could be pursued.

“…Nanofluidic channels and nanopores allow for ion transport manipulation that parallels electronic devices such as field effect transistors (FETs) [1] and diodes [2]. Recently, tunable transport characteristics and diode behavior have been demonstrated in NCAMs through induced charge inversion [16,17]. An applied potential across the length of a channel drives an electroosmotic flow.…”
