“…Herein, carbon nanotubes were used to mimic channels, that are embedded in cell membranes [3]. They can act as arti cial water channel that form a transmembrane pore that enhance the membrane permeability for lipophilic drugs [2].

Fungicides of huge organic chemical structures may face some hindrance in passage across membranes of ion-selective electrodes. Thus, the invention of passages within the membrane matrix that selectively engulf these compounds, facilitating their transfer through the membrane. Carbonaceous materials of nanosized range showed superior ability in increasing ion transfer in comparison with carbon nanotubes. Their combination with acrylates-polymerized-cyclodextrin as ionophore, created two pathways for large organic molecules across the membrane. Application of both inventions in fabrication of three sensors using carbon nanotubes, graphene quantum dots, and nanographene oxide, enabled trace analysis of azoxystrobin fungicide in ranges (10-12 -10-5, 10-13 -10-4 and 10-13 -10-6 M), respectively, with high selectivity.

Large molecules pass the biological membranes through accessory elements, either carriers (ionophores) and/or water channels. Ionophores shield the charge of the target ion, enabling it to cross the membrane to be released on the other side. This may consume time and some huge structures need a bulky ionophore. However, water channels enable the passage of many ions at a high rate without the need for carriers that may limit the ion transfer rate. Simulation of living cell membrane in engulfing large molecules through channels is a very interesting mechanism to enhance permselectivity of fabricated polyvinyl chloride (PVC) membrane sensors. Green synthesis of carbonaceous nanoparticles to play this role was fulfilled in nanocarbon dots (CD). The polymerization of βcyclodextrin with acrylates, either imprinted with the target molecule (in molecularly imprinted polymer, MIP) or not (in non-imprinted polymer, NIP) provided a good enhancement of binding selectivity, in comparison with βcyclodextrin alone as ionophore. Application of both inventions in the fabrication of three sensors (1; CD/βCD, 2; CD/NIP, and 3; CD/MIP) enabled trace analysis of azoxystrobin fungicide in ranges (10 -11 -10 -5 , 10 -13 -10 -4 and 10 -13 -10 -4 M), respectively, with high selectivity.

Natural Aquaporin (AQP) channels are efficient water translocating proteins, rejecting ions. Inspired by this masterpiece of nature, Artificial Water Channels (AWCs) with controlled functional structures, can be potentially used to mimic the AQPs to a certain extent, offering flexible avenues toward biomimetic membranes for water purification. The objective of this paper is to trace the historical development and significant advancements of current reported AWCs. Meanwhile, we attempt to reveal important structural insights and supramolecular self‐assembly principles governing the selective water transport mechanisms, toward innovative AWC‐based biomimetic membranes for desalination.
