Abstract
Chiral separation membranes have shown great potential for the efficient separation of racemic mixtures into enantiopure components for many applications, such as in the food and pharmaceutical industries; however, scalable fabrication of membranes with both high enantioselectivity and flux remains a challenge. Herein, enantiopure S-poly(2,4-dimethyl-2-oxazoline) (S-PdMeOx) macromonomers were synthesized and used to prepare a new type of enantioselective membrane consisting of a chiral S-PdMeOx network scaffolded by graphene oxide (GO) nanosheets. The S-PdMeOx-based membrane showed a near-quantitative enantiomeric excess (ee) (98.3±1.7 %) of S-(-)-limonene over R-(+)-limonene and a flux of 0.32 mmol m-2 h-1 . This work demonstrates the potential of homochiral poly(2,4-disubstituted-2-oxazoline)s in chiral discrimination and provides a new route to the development of highly efficient enantioselective membranes using synthetic homochiral polymer networks.

Abstract
A nanochannel membrane has the prospect of large-scale separation. However, selectivity in enantioseparation is a challenge, due to the size difference between nanochannels and enantiomers. Here, we compartmented nanochannels by the in situ synthesis of a L-tyrosine functionalized covalent organic framework (L-Tyr-COF). The L-Tyr-COF decreased the pore size of channels to match with naproxen enantiomers (S/R-NPX) and improved the enantioselective gating. In contrast to the surface-functionalized nanochannels (L-Tyr channel), the L-Tyr-COF packed nanochannels (L-Tyr-COF channel) exhibited high enantioselectivity for S-NPX and realized the enantioseparation with the enantiomer excess value up to 94.2 %. The separation flux through the highly porous L-Tyr-COF channel was 1.33 mmol m-2 h-1 . This study provided a size-matching strategy and the chiral covalent organic framework packed nanochannel membrane to realize enantioseparation with high selectivity and flux.

Abstract
Inspired by the nuclear pore complex (NPC), herein we have established a biomimetic high-flux protein delivery system via the ingenious introduction of pillar[5]arene-based host-guest system into one side of artificial hour-glass shaped nanochannel. With a transport flux of 660 lysozymes per minute, the system provides efficient high-flux protein transport at a rate which is significantly higher than that of an unmodified nanochannel and conventional bilateral symmetrical modified nanochannels. In view of these promising results, the use of artificial nanochannel to improve protein transport not only presents a new potential chemical model for biological research and better understanding of protein transport behavior in the living systems, but also provides a high-flux protein transporter device, which may have applications in the design of protein drug release systems, protein separation systems and microfluidics in the near future.

Abstract
Chiral discrimination has gained much focus in supramolecular chemistry, since it is one of the fundamental processes in biological systems, enantiomeric separation and biochemical sensors. Though most of the biochemical processes can routinely recognize biological enantiomers, enantioselective identification of chiral molecules in artificial systems is currently one of the challenging topics in the field of chiral discrimination. Inaccuracy, low separation efficiency and expensive instrumentation were considered typical problems in artificial systems. Recently, chiral recognition on the interfaces has been widely used in the fields of electrochemical detection and biochemical sensing. For the moment, a series of macrocyclic host functionalized interfaces have been developed for use as chiral catalysts or for enantiomeric separation. Here, we have briefly exposited the most recent advances in the fabrication of supramolecular functionalized interfaces and their application for chiral recognition.

Abstract
This work focused on designing a novel redox-responsive nanocarrier synthesized from carboxymethyl-β-cyclodextrin-modified nanosilica, which could load and release plant hormones, such as salicylic acid (SA), in plant cells. When the SA-loaded nanoparticles cross the plant cell wall, the disulfide bond can be broken to form sulfhydryl groups under the action of reduced glutathione (GSH), thus releasing SA. Meanwhile, the resulting thiol groups exhibited strong affinity toward several heavy metal ions, mercury ions in particular, thus playing a role similar to phytochelatins for detoxification. The results of SA release in vitro proved that the release proceeded much faster in GSH-rich than in GSH-free environments. The adsorption behaviors of the redox-responsive nanoparticles toward heavy metal ions, after phytohormones release, were systematically investigated. Moreover, the synergetic effects on sustained release and metal ion capture enable the redox-responsive cyclodextrin-modified silica to be an effective and dual-functional nanocarrier that has great potential for agricultural applications.

Abstract
Polydimethylsiloxane-2-[2-tert-Butoxycarbonylamino-(1H-pyrazol-4-yl)-propionylamino] -3-phenyl-propanoic acid (PDMS-BCPA) is a newly developed stereo-specific membrane that interacts with S configuration of enantiomers as chiral recognition sites. In this study, realization of PDMS-BCPA nanomembrane was achieved via anodized aluminum oxide (AAO) template synthesis approach followed by the attachment of synthesized chiral selector (BCPA) using simple immersion method. The effect of surface modification and the attachment with chiral selector were investigated and characterized using Fourier Transform Infrared spectroscopy (FT-IR), Field Emission Scanning Electron Microscopic (FE-SEM) and Atomic Force Microscopic (AFM) methods. The characterization via these methods indicates the synthesized BCPA as chiral selector was successfully attached onto the PDMS surface. The enantioselectivity of PDMS-BCPA nanomembrane was verified by the separation of alpha cypermethrin enantiomer.
