Abstract
Nanopore sensing technology, as an emerging analytical method, has the advantages of simple operation, fast output, and label-free and has been widely used in fields such as protein analysis, gene sequencing, and biomarker detection. Inspired by biological ion channels, scientists have prepared various artificial solid-state nanopores/nanochannels. Biological ion channels have extremely high ion transport selectivity, while solid-state nanopores/nanochannels have poor selectivity. The selectivity of solid-state nanopores and nanochannels can be enhanced by modifying channel charge, varying pore size, incorporating specific chemical functionality, and adjusting operating (or solution) conditions. This Perspective highlights pore-in modification strategies for enhancing the selectivity of solid-state nanopore/nanochannel sensors by summarizing the articles published in the last 10 years. The future development prospects and challenges of pore-in modification in solid-state nanopore and nanochannel sensors are discussed. This Perspective helps readers better understand nanopore sensing technology, especially the importance of detection selectivity. We believe that solid-state nanopore/nanochannel sensors will soon enter our homes after various challenges.

Abstract
Changes in the charge density on the inner surface of the microchannel can modulate the ion concentration at the tip, thus causing changes in the resistance of the system. In this study, this property is adopted to construct a portable sensor using a multimeter and aflatoxin B1 (AFB1) is used as the model target. Initially, the cDNA/aptamer complex is modified in the microchannel. The inner microchannel surface's charge density is then altered by the recognition of the target, leading to a change in the system's resistance, which can be conveniently monitored using a multimeter. Critical parameters influencing the performance of the system are optimized. Under optimum conditions, the resistance is linearly related to the logarithm of AFB1 concentration in the range of 100 fM-10 nM and the detection limit is 46 fM (S/N = 3). The resistive measurement is separated from the recognition reaction of the target, reducing the matrix interference during the detection process. This sensor boasts high sensitivity and specificity coupled with commendable reproducibility and stability. It is applied to assay the AFB1 content successfully in an actual sample of corn. Moreover, this approach is cost-effective, user-friendly, and highly accurate.

Abstract
Chiral flavor substances play an important role in the human perception of different tastes. Here, we report a pure covalent-organic framework (COF) membrane nanochannel in combination with a chiral gold nanoparticles (AuNPs) selector for sensing chiral flavor substances. The pure COF membrane with a proper pore size is selected as the nanochannel, while l-cysteine-modified AuNPs (l-Cys-AuNPs) are used as the chiral selector. l-Cys-AuNPs show stronger binding to the S-enantiomer than the R-enantiomer, causing current reduction to different degrees for the R- and S-enantiomer to achieve chiral sensing due to the synergistic effect of the size exclusion of the COF nanochannel and the chiral selectivity of l-Cys-AuNPs. The developed COF membrane nanochannel sensing platform not only allows an easy balance of the permeability and selectivity, which is difficult to achieve in traditional polymer membrane nanochannel sensors, but also exhibits better chiral performance than commercial artificial anodic aluminum oxide (AAO) nanochannel sensors. The developed nanochannel sensor is successfully applied for sensing flavor enantiomers such as limonene, propanediol, methylbutyric acid, and butanol with the enantiomer excess values of 55.2% (propanediol) and 72.4% (limonene) and the low detection limits of 36 (limonene) and 71 (propanediol) ng L-1. This study provides a new idea for the construction of nanochannel platforms based on the COF for sensitive and selective chiral sensing.

Abstract
To develop high-efficiency antibiotic adsorbents, β-cyclodextrin and dopamine hydrochloride were used to modify graphene oxide to prepare a new type of ternary composite material (β-cyclodextrin/dopamine hydrochloride-graphene oxide, CD-DGO). The material was characterized using scanning electron microscopy, Fourier infrared spectrometry, transmission electron microscopy, and specific surface area optical analysis. Two typical sulfonamides antibiotics (sulfamethoxazole, sulfadiazine) adsorption capacity were evaluated in terms of the dosage of composite materials, the ratio of each component, and the pH of the solution. We analyzed the adsorption characteristics via adsorption kinetics and adsorption isotherms, and then investigated the stability of the adsorbent through desorption and regeneration of the adsorbent. The results show that the adsorption effect of sulfonamides antibiotics is best at pH = 2; the adsorption kinetics conform to the pseudo-second-order kinetic model, and the adsorption equilibrium follows the Langmuir adsorption isotherm; the maximum adsorption capacity of CD-DGO for sulfamethoxazole and sulfadiazine is 144 mg·g-1 and 152 mg·g-1, respectively. The material has good reusability, and the dominant force in the adsorption process is the π-π electron conjugation effect with hydrogen bonding. This offers a theoretical basis for the treatment of sulfonamides antibiotics water pollution.

Abstract
DNA methylation is catalyzed by a family of DNA methyltransferases that play crucial roles in various biological processes. Therefore, an ultrasensitive methyltransferase assay is highly desirable in biomedical research and clinical diagnosis. However, conventional assays for the detection of DNA methyltransferase activity often involve radioactive labeling, costly equipment, and laborious operation. In this study, an ultrasensitive and label-free method for detecting DNA adenine methyltransferase (Dam) and CpG methyltransferase (M.SssI) was developed using the nanopore technique coupled with DNA cascade signal amplification reactions. A hairpin DNA (HD) comprising of the methylation-responsive sequences was skillfully designed. In the presence of Dam methyltransferase, the corresponding recognition site of hairpin HD was methylated and specifically cleaved by DpnI endonuclease, thus forming a DNA fragment that induces the catalytic hairpin assembly and hybridization chain reaction (CHA-HCR). The generated products could be absorbed onto the Zr4+-coated nanopore, resulting in an ion current rectification signal change. Considering the high sensitivity of the nanopore and excellent specificity toward the recognition of methyltransferase/endonuclease, our developed method could detect both Dam and M.SssI methyltransferases in the same sensing platform. Furthermore, the designed nanopore sensor could realize the multiplex detection of Dam and M.SssI methyltransferases after integration with the cascaded INHIBIT-AND logic gate. This ultrasensitive methyltransferase assay holds great promise in the field of cancer diagnosis.

Abstract
Bio-inspired polymeric nanochannel (also referred as nanopore)-based biosensors have attracted considerable attention on account of their controllable channel size and shape, multi-functional surface chemistry, unique ionic transport properties, and good robustness for applications. There are already very informative reviews on the latest developments in solid-state artificial nanochannel-based biosensors, however, which concentrated on the resistive-pulse sensing-based sensors for practical applications. The steady-state sensing-based nanochannel biosensors, in principle, have significant advantages over their counterparts in term of high sensitivity, fast response, target analytes with no size limit, and extensive suitable range. Furthermore, among the diverse materials, nanochannels based on polymeric materials perform outstandingly, due to flexible fabrication and wide application. This compressive Review summarizes the recent advances in bio-inspired polymeric nanochannels as sensing platforms for detection of important analytes in living organisms, to meet the high demand for high-performance biosensors for analysis of target analytes, and the potential for development of smart sensing devices. In the future, research efforts can be focused on transport mechanisms in the field of steady-state or resistive-pulse nanochannel-based sensors and on developing precisely size-controlled, robust, miniature and reusable, multi-functional, and high-throughput biosensors for practical applications. Future efforts should aim at a deeper understanding of the principles at the molecular level and incorporating these diverse pore architectures into homogeneous and defect-free multi-channel membrane systems. With the rapid advancement of nanoscience and biotechnology, we believe that many more achievements in nanochannel-based biosensors could be achieved in the near future, serving people in a better way.
