摘要：
As a common substance in the human body, melibiose has a good effect on treating inflammation, and chiral selectively assembled behaviors often accompany this metabolic activity. Therefore, studies on melibiose's chiral selectively assembled behaviors arouse broad interest, making it better for us to understand similar bioprocesses. Herein, we modified (R)/(S)-phenylethylamine calix[4]arenes onto the gold surface to analyze the chiral selective behaviors for melibiose. Contact angle and electrochemical experimental results showed that this functional surface modified with (S)-phenylethylamine calix[4]arene achieved selective adsorption of melibiose in the condition of pH = 7 based on the weak host-guest interaction. Furthermore, these functional surfaces have been realized by amplifying the weak selective interaction, and these chiral selective sensors have been constructed for the melibiose.

摘要：
By mimicking nature, various artificial nanofluidic platforms have been widely applied in a range of scientific fields. However, their low performance in terms of gating efficiency (<25) still hinders their practical applications. Herein, we present a highly efficient ionic gating nanosensor by fusing the merits of host-guest chemistry and Au nanoparticles (AuNPs). Based on this strategy, the pillar[6]arene (WP6)-functionalized AuNPs facilely regulated an azobenzene (AZO)-modified nanosensor with an excellent ion rectification ratio (∼22.2) and gating efficiency (∼89.5). More importantly, this gating nanosensor system also demonstrated promising stability and recyclability under conditions of alternative irradiation of visible and ultraviolet light. These excellent results would significantly help in expanding the utilization of artificial nanosensors for controllable drug delivery and biosensors. © 2021 The Authors.

摘要：
Inspired by the light-regulating capabilities of naturally occurring rhodopsin, we have constructed a visible-light-regulated Cl−-transport membrane channel based on a supramolecular host–guest interaction. A natural retinal chromophore, capable of a visible-light response, is used as the guest and grafted into the artificial channel. Upon introduction of an ethyl-urea-derived pillar[6]arene (Urea-P6) host, threading or de-threading of the retinal and selective bonding of Cl− can be utilized to regulate ion transport. Based on the visible-light responsiveness of the host–guest interaction, Cl− transport can be regulated by visible light between ON and OFF states. Visible-light-regulated Cl− transport as a chemical model permits to understand comparable biological ion-selective transport behaviors. Furthermore, this result also supplies a smart visible-light-responsive Cl− transporter, which may have applications in natural photoelectric conversion and photo-controlled delivery systems. © 2020 Wiley-VCH GmbH

摘要：
Enantiomers of various drug molecules have a specific effect on living organisms. Accordingly, developing a sample method for the efficient and rapid recognition of chiral drug enantiomers is of great industrial value and physiological significance. Here, inspired by the structure of ion channels in living organisms, we developed a chiral nanosensor based on an artificial tip-modified nanochannel system that allows efficient selective recognition of chiral drugs. In this system, l-alanine-pillar[5]arenes as selective receptors were introduced on the tip side of conical nanochannels to form an enantioselective 'gate'. The selective coefficient of our system toward R-propranolol is 4.96, which is higher than the traditional fully modified nanochannels in this work. © 2021 American Chemical Society.

摘要：
Nanopore-based detection techniques, with a wide range of transport properties, exhibit impressive selectivity and sensitivity for analytes. To expand the application of nanoporous sensors, real-time and fast detection of targets, all within a portable device, is highly desired for nanopore-based sensors. In addition, to improve the accuracy of the output signal, more appropriate readout methods also need to be explored. In this manuscript, we describe a nanopore-based electrode, regarded as NAC-P6-PC@AuE, prepared by coupling a pillararene-based nanoporous membrane with an electrochemical impedance measurement method. The fabricated device is demonstrated by exposing pillararene-based receptors to trace amounts of pesticide molecules. NAC-P6-PC@AuE devices exhibit distinguished selectivity to quinotrione, as well as the ability to quantify quinotrione with a limit of quantitation (LOQ) of 10 nM. The mechanism that allows sensing was verified using finite-element simulations and may be explained as host-guest-induced surface charge shielding, which influences the electrochemical response of probe molecules. The applications of this nanopore-based electrode may be extended toward other target molecules by decorating the nanopore surfaces with specifically chosen receptors. ©

摘要：
Two commonly observed charge transport mechanisms in single-molecule junctions are coherent tunneling and incoherent hopping. It has been generally believed that tunneling processes yield temperature-independent conductance behavior and hopping processes exhibit increasing conductance with increasing temperature. However, it has recently been proposed that tunneling can also yield temperature-dependent transport due to the thermal broadening of the Fermi energy of the contacts. In this work, we examine a series of rigid, planar furan oligomers that are free from a rotational internal degree of freedom to examine the temperature dependence of tunneling transport directly over a wide temperature range (78-300 K). Our results demonstrate conductance transition from a temperature-independent regime to a temperature-dependent regime. By examining various hopping and tunneling models and the correlation between the temperature dependence of conductance and molecular orbital energy offset from the Fermi level, we conclude thermally assisted tunneling is the dominant cause for the onset of temperature-dependent conductance in these systems. © 2021 American Chemical Society.

摘要：
Chirality is a fascinating and essential feature of life and highly associated with many significant pharmaceutical, chemical, and biological processes. The construction of chiral recognition platform is a hot research topic and challenging assignment. Herein, we report an electrochemical method by differential pulse voltammetry (DPV) for the enantioselective recognition of chiral drug propranolol (R/S-PPL) through a nanochannel platform based on the N-acetyl-L-cysteine functionalized pillar[5]arenes derivative NALC-P5 and the porous polycarbonate membrane. The chiral discrimination depends on the difference in the supramolecular host-guest interaction between the chiral NALC-P5 and the R/S-PPL. The transmission rate of the R/S-PPL can be regulated in the nanochannel and we can achieve the selective transport of the chiral drugs. This simple electrochemical technique has potential applications as a general platform for the recognition of chiral molecules.

摘要：
Photoresponsive azobenzene-cyclodextrin light-switches fabricated artificial film which can be used to regulate the transmission of glutathione (GSH) across the membrane will gain much significance due to the important role of GSH in various biological process. In this work, we used azobenzene-cyclodextrin complex as switchable unit to manipulate gating transport. Under the control of ultraviolet (UV 365 nm) and visible (Vis 430 nm) light, two states of “ON” and “OFF” transport of GSH can be realized by the switches. This study achieved controlled molecule transport through channels by taking GSH as the research object, providing a new theoretical model for biological research and hold promise for future applications such as light-controlled drug transmission. © 2020 Elsevier B.V.

摘要：
Chiral-specific assembly is involved in many biochemical processes, such as DNA hybridization, protein adhesion, and sugar recognition. However, the signals of chiral interaction are usually very weak, and it is difficult to investigate the enantioselective behaviors. Therefore, it is necessary to construct the functional materials to regulate the selective behaviors of protein droplets via weak chiral interaction, which is also significant for the biological process of protein adhesive behaviors and proteinic drug delivery. Here, S- and R-amino alcohol derivative of calix[4]arene enantiomers (R/S-AC4) were synthesized and modified onto Au-surfaces to fabricate the enantiomer's materials and investigate the chiral selective adhesion of protein droplets. Through the experiment of fluorescence titration and molecular docking simulation, bovine serum albumin (BSA) showed the stronger interaction with R-amino alcohol-calix[4]arene than S-amino alcohol-calix[4]arene on the molecular level. Notably, the sliding angle showed that the droplet of BSA selectively adhered to the R-amino alcohol-calix[4]arene-modified surface, while it released rapidly from S-amino alcohol-calix[4]arene-modified surface by virtue of chiral selectivity. This result not only provides an easy and convenient model to regulate the selective adhesion and release of protein from chemical view, but also realizes the signal transduction through the weak chiral interaction. © 2020 American Chemical Society.

摘要：
Promoting the spreading and deposition of agricultural sprays on the crop surface is of great significance for effective utilization of these chemicals. Selective host-guest interaction established between chlormequat and hydroxyl pillar[5]arene was well utilized in the present work for effective spreading of chlormequat droplets over the hydrophobic surface, which was silanized with triethoxy (octyl) silane and then assembled with hydroxybenzene pillar[5]arene molecules. Therefore, this surface was facile for the assembly of chlormequat in droplets and ultimately increased the selective adhesion of chlormequat through host-guest interactions. Moreover, the pillar[5]arene-fabricated surface shows considerable potential applications for rapid detection of chlormequat in environmental monitoring and also provides a novel approach for improving the chlormequat efficiency.

摘要：
The two-dimensional surfaces have been fueled by the infinite possibility they offe red fo r basic re search,and for novel technologies in nanoelectronics.To realize many of these promises,the effective strategies were to design and control their surface chemistry,which plays a vital role in determining the chemical and physical properties.Macrocyclic host-guest chemistry with the reversible noncovalent interactions between macrocyclic hosts and suitable guests can be readily used for constructing multifunctional surfaces.Macrocyclic pillararenes,possessed the unique structure,have attracted the attentions of researchers in recent years.This feature article covers the recent development of pillararene-based twodimensional inte rfaces,including the fabrication and function of the hybrid composite.The combination of pillararenes and materials platform exhibited the novel property because of the characte ristic of cavity of macrocyclic host and confined spaces of surfaces.We anticipate that this review will be helpful to the researchers working in the fields of supramolecular chemistry and materials science.

摘要：
Spreading of agricultural sprays on plant surfaces is a significant task as it helps decrease pesticide usage and thereby reduces the risk of environmental pollution. Here, we report a method of increasing the spreading of herbicide benquitrione droplets on superhydrophobic surfaces through its selective dynamic self-assembly with amino pillar[5]arenes. Supramolecular interaction such as host-guest interaction was utilized for the complete diffusion of benquitrione over the hydrophobic plant surface. Furthermore, molecular dynamics simulations were used to verify that AP5A improved the spreading of benquitrione droplets on superhydrophobic interfaces. Moreover, complexation of benquitrione did not affect its biological activity. The present work provides a new method for improving the utilization rate of pesticides and reducing pesticide use. © The Royal Society of Chemistry.

摘要：
The fabrication of a membrane with the capability of chiral selective transport is a big challenge in the membrane separation of chiral drugs. To solve the problem of chiral selectivity in membrane separation, drug/metabolite transport (DMT) in the cell membrane inspires a bionic strategy based on the nanochannel membrane. Herein, the DMT-inspired nanochannel membrane is fabricated by the self-assembly of cyclodextrin (CD) in nanochannels and used for the chiral transport and separation of model chiral drugs such as naproxen (NAP). As a result, the β-CD-self-assembled nanochannel membrane shows chiral transport of (S)-naproxen (S-NAP) and achieves the chiral separation of racemic drugs. Moreover, a mechanism of chiral separation is proposed that the chiral selective interaction increases the surface charge density, causing chiral enrichment and transport. Given these promising results, the study of the β-CD-self-assembled nanochannel membrane suggests a bionic strategy for the separation of chiral drugs. © 2020 American Chemical Society.

摘要：
N-acetylglucosamine analogues exist in nature as an important saccharide in human body and can regulate a variety of life activities captured through biological nanochannels. Herein we describe a biomimetic strategy via supramolecular host-guest chemistry for constructing artificial nanochannels to detect N-acetylglucosamine analogues. The functional nanochannels exhibited a high selectivity and good reversibility towards N-acetylglucosamine. Further studies indicate that the detecting behaviors was probably due to the multiple hydrogen bonding interactions and an appropriately fitting the functional and geometric requirements between the tryptophan-decorated pillararenes and N-acetylglucosamine, leading to the change of the surface charge and wettability within the nanochannels. These studies can give interesting insight for the research of biological processes caused by N-acetylglucosamine-sensitive ion channels, and also help to develop the platform for detecting N-acetylglucosamine in vitro.

摘要：
Nitric oxide (NO) is known to be a secondary in vivo signaling agent, demonstrating various biological functions through regulating ion flux in channels. Considering the crucial role of NO in vivo, herein, a biomimetic NO-regulated nanofluidic sensor has been fabricated through a cyclization reaction strategy. This nanofluidic sensor exhibited a promising NO selectivity, sensitivity, and non-interference performance in complex matrices. Thus, such a NO-driven nanosensor will be meaningful for scientific researchers to grasp the in vivo functions of NO. © 2020 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim

摘要：
Triphenyl phosphate (TPhP), a typical model of organophosphorus flame retardants (OPFRs), has been regarded as emerging environmental contaminants of health concern. In this study, TPhP molecularly imprinted polymers immobilized on graphene oxide (GO) film (TPhP-MIPs/GO) monolithic fiber for direct immersion solid phase microextraction (DI-SPME) was fabricated and evaluated. Compared with TPhP molecularly imprinted polymers (TPhP-MIPs) monolithic fiber, TPhP-MIPs/GO fiber had bigger extraction capacity, stronger hydrophilicity and faster mass transfer rate. Furthermore, TPhP-MIPs/GO fiber displayed excellent selectivity for TPhP among its structure analogues. It was thermally stable up to 320 degrees C so that it can withstand the high temperature of gas chromatography (GC) injection port for desorption and detection by flame photometric detector (FPD). Under optimal conditions, TPhP-MIPs/GO-SPME-GC/FPD method was developed by yielding satisfactory ultralow limit of quantification (0.4 ng L-1); linearity (>= 0.99), good intra- and inter-day precision for a single fiber and fiber-to-fiber reproducibility. The method was applied for the determination of TPhP in environmental water and the relative recoveries were found to be in the range from 70 to 110%. TPhP was detected in three out of four environmental water samples at concentration levels from 0.04 to 0.12 ng mL(-1), illustrating light pollution of TPhP in most environmental water.

摘要：
In the life system, the biointerface plays an important role in cell adsorption, platelet adsorption and activation. Therefore, the study of protein adsorption on the biointerface is of great significance for understanding life phenomena and treatment in vitro. In this paper, a chiral biointerface was constructed by the virtue of host-guest interaction between a water-soluble pillar[5]arene (WP5) and phenethylamine (PEA) over a gold surface for adsorption of lysozyme proteins. From the experimental results it was identified that the host-guest biointerface has a high adsorption capacity and strong chiral selectivity. Furthermotre, it was identified that the host-guest interaction plays the decisive role in the enhancement of chirality of the interface, which was much beneficial for increasing protein adsorption and amplifying the capacity of chiral discrimination. Therefore, this work provides a new idea for the construction of biointerface materials with high protein adsorption capacity and high chiral selectivity through supramolecular interaction, which will have potential applications in the fields of biosensors, biocatalysts, biomaterials. © 2020 Wiley-VCH Verlag GmbH & Co.

摘要：
This work reports on glutathione modified Ag nanoparticles (GSH-Ag NPs) as a chemosensor for detecting pyrimethanil in an aqueous medium. The GSH-Ag NPs were expediently obtained by reducing AgNO3 with NaBH4 and modified with glutathione based on the Ag-S bond. The rapid discrimination for pyrimethanil from other pesticides exhibited the high selectivity of GSH-Ag NPs, then the selectivity was proved by 1H NMR, FT-IR and computational simulation. Based on the good properties of localized surface plasmon resonance, the selective recognition was transformed to visible optical signal in colorimetric test. Additionally the quantitative detection was achieved with good sensitivity and could be applied to analyze practical samples. The experimental results have shown a good linear relationship with pyrimethanil concentration ranging from 10 μM to 1 mM and a low detection limit of 3.87 μM. © 2019 IOP Publishing Ltd.
