Ni3S2/MoS2 heterostructures hold substantial promise as bifunctional catalysts, owing to their synergistic electronic characteristics and plentiful active sites. However, their catalytic efficacy is impeded by the relatively elevated chemisorption energy of hydrogen-containing intermediates, which constrains their functionality in different pH environments. In order to mitigate this limitation, trace amounts of Pt are introduced into the heterostructure, intending to enhance electronic transport and refining chemisorption energies, thereby facilitating significant enhancements in both hydrogen evolution reaction and oxygen evolution reaction activities over a wide pH range. It is revealed that the Pt-modified catalyst achieves exceptional HER performance, requiring merely 64 mV and 83 mV overpotentials to attain a current density of 100 mA cm⁻² in acidic and alkaline media, respectively. Furthermore, theoretical simulations corroborate that Pt modification optimizes local electronic configurations and augments electronic transfer, contributing to its superior catalytic performance. This investigation underscores the pivotal role of Pt modification in propelling the practical application of Ni3S2/MoS2 heterostructures as highly efficient and pH-universal bifunctional catalysts.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"47 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Approximately 60%–90% of patients with advanced cancer experience debilitating pain. Therefore, a comprehensive treatment system that combines cancer pain suppression and tumor treatment could provide significant benefits for these patients. Here, we designed a manganese oxide (MnO2)/Bovine serum albumin (BSA)/polydopamine (PDA) composite nanoplatform internally loaded with capsaicin for cancer pain suppression and immunotherapy. MBD&C nanoparticles (NPs) can ablate tumor-innervated sensory nerve fibers via Transient receptor potential vanilloid 1 (TRPV1) channels, thereby reducing the pain caused by various inflammatory mediators. The ablation of TRPV1+ nerve terminals can also decrease the secretion of calcitonin gene-related peptide (CGRP) and substance P (SP) in sensory nerve fibers, thus reducing the tumor pain and inhibit tumor progression. MBD&C can promote calcium influx by activating overexpressed TRPV1 channels on the tumor membrane surface, thereby achieving cancer immunotherapy induced by endogenous Ca2+ overloading. In addition, MnO2 NPs can alleviate tumor hypoxia and mitigate the immunosuppressive tumor microenvironment (TME). Ultimately, this treatment system with dual capabilities of inhibiting tumor growth and relieving cancer pain makes comfortable tumor therapy feasible and paves the way for the development of patient-centered approaches to cancer treatment in the future.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"38 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, we explore the peptide/gold interface owing to its significance in various topics and its suitability to perform experiments both in model and real conditions. Experimental results show that the studied peptide adopts a lying configuration upon adsorption on the gold surface and interacts through its peptidic links and deprotonated thiolate extremities, in agreement with theoretical predictions. Single-molecule force spectroscopy (SMFS) measurements revealed the existence of a wide panel of adhesion forces, resulting from the interaction between individual peptide moieties and the abundant surface sites. We therefore propose methodological developments for sorting the events of interest to understand the peptide adsorption mechanism. Thermodynamic and kinetic aspects of the peptide adsorption are probed using both static and dynamic force spectroscopy measurements. Specifically, we show the possibility of providing a reasonable estimate of the peptide free energy of adsorption ΔadsG° by exploring the fluctuations of the adhesion work, based on the Jarzynski equality, and by using a parametric Gamma estimator. The proposed approach offers a relevant method for studying the different factors influencing the peptide adsorption and evaluating their impact on ΔadsG° as an alternative to exploring adhesion forces that may lead to misinterpretations. This is illustrated by the comparison of the adsorption of two peptides with specific amino acids substitution. Our method provides insights into the overall mechanim by which peptides interact with the surface and allows an integration of the single-molecule versus ensemble-average points of view.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"12 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it is known that the material of confinement has a significant influence on the properties of confined water, much less is known of the relationship between the structure of nanoconfined water and its properties, impacting the design of nanofluidic devices. We explore the behavior of a confined water monolayer within a bilayer molybdenum disulfide (MoS2) structure, comparing its behavior with that within bilayer graphene. We find that only ∼2% of the entire structure has nearly perfect square order and the rest is filled with rhombus ordering. Surprisingly, we find that although the structure of monolayer confined water remains the same in both the 2D materials, thermodynamic analysis shows that confined water has a more favorable potential environment in MoS2 than graphene for all twists explored here. However, with increasing twist angle, the encapsulating effect of water diminishes slightly in the case of graphene than MoS2. Interestingly, the dielectric constant is anomalously lower in MoS2 by ∼22% compared to the confined water dielectric constant in a graphene nanochannel. Finally, we show that the static friction coefficient of confined water in bilayer MoS2 does not change with twist. However, unlike graphene, it does not show an order of magnitude reduction due to this extreme confinement. Overall, we show, counter-intuitively, that although confined water structures are similar in different 2D materials considered here, there exist differences in other properties of this structured water.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"40 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advances in DNA nanotechnology have introduced DNA nanomaterials as promising tools to overcome these barriers. This review focuses on three primary categories of DNA nanomaterials applied in RA: DNA nanostructures, DNA aptamers, and DNA-modified nanoparticles. DNA nanostructures, such as tetrahedral framework nucleic acids (tFNAs) and DNA origami, demonstrate anti-inflammatory properties and facilitate precise, controlled drug delivery. DNA aptamers, functioning as molecular recognition ligands, surpass traditional antibodies with their high specificity, low immunogenicity, and thermal stability, offering significant potential in biomarker detection and therapeutic interventions. While DNA-modified nanoparticles, which integrate DNA with materials like gold or lipids, have shown significant progress in bioimaging and drug delivery in other fields, their application in RA remains limited and warrants further exploration. Further, advancements in stimulus-responsive systems are being explored to enable controlled drug release, which could significantly improve the specificity and efficiency of DNA nanomaterials in therapeutic applications. Despite their immense potential, challenges such as stability under physiological conditions, safety concerns, and clinical regulatory complexities persist. Overcoming these limitations is essential. This review highlights how DNA nanomaterials, beyond serving as delivery platforms, are poised to redefine RA treatment and diagnosis, opening the door to more personalized and effective approaches.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"30 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ternary composite demonstrated exceptional photocatalytic activity, with the optimized 10%PANI/GO/α-Fe2O3 (10PGF) photocatalyst achieving 99.8% degradation of BrG in 25 min and 93% CIP in 90 min of irradiation.

The rate constant of BrG degradation was 15 and 10 times faster than PANI and α-Fe2O3, respectively, while CIP degraded 8.9 and 6.1 times faster. The degradation of the pollutants was facilitated by both O2•− and •OH, confirmed by capturing active species, nitroblue tetrazolium test and PL terephthalic acid probe. The proposed Z-scheme mechanism elucidated the charge carrier movements and active species involvement, revealing the enhanced photocatalytic performance of the ternary composite. The 10PGF ternary composite demonstrated exceptional recyclability over five repeated cycles, with XRD analysis confirming no structural changes in the material.

These diverse nanostructures represent different energy states in the free energy landscape, that have been created through different self-assembling pathways by providing variable energy input by simply altering the gelation induction temperatures from 40-90°C. The higher entangled network structure with long fibers was created by higher energy input, i.e., inducing the gelation at higher temperature from 70-90°C, whereas the less entangled nanoscale network with short fibers were obtained at a lower gelation induction temperature over 40-60°C. It is worth mentioning that the higher entangled network structures with long fibers that can be easily accessed by heating the less order structure, as evidenced by the thermoreversibility study. In addition, tuneable mechanical properties were also achieved by merely adjusting the self-assembly pathways; the gels formed at higher gelation induction temperatures showed higher mechanical strength in contrast to the gels formed at lower gelation induction temperatures. Further, a detailed comparison was made with one of the important ECM proteins, i.e., collagen to elucidate the potential of the hydrogels in mimicking the structural and mechanical properties of ECM. Interestingly, the highly entangled network structures with long fibers enhanced cellular survival as well as adhesion, comparable to that of the collagen gel, while a considerable proportion of cells were unable to adhere to the kinetically trapped less entangled structures with short fibers. Such diverse nanostructures in a single gelator regime can be instrumental in controlling differential cellular behaviour and it could further pave the path for the development of responsive biomaterials.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"11 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With growing interest in the material, it is critical to understand its layer-number-dependent properties and develop strategies for controlling them. Here, we demonstrate a photo-modulation of MoS2 flakes and elucidate layer-number-dependent charge transfer behaviors. We fabricated hybrid structures by functionalizing MoS2 flakes with a uniform layer of photochromic diarylethene (DAE) molecules that can switch between closed- and open-form isomers under UV and visible light, respectively. We discovered that the closed-form DAE quenches the photoluminescence (PL) of monolayer MoS2 when excited at 633 nm and that the PL fully recovers after DAE isomerization into the open-form. Similarly, the electric conductivity of monolayer MoS2 is drastically enhanced when interacting with the closed-form isomers. In contrast, photoinduced isomerization did not modulate the properties of the hybrids made of MoS2 bilayers and trilayers. Density functional theory (DFT) calculations revealed that a hole transfer from monolayer MoS2 to the closed-form isomer took place due to energy level alignments, but such interactions were prohibited with open-form DAE. Computational results also indicated negligible charge transfer at the hybrid interfaces with bilayer and trilayer MoS2. These findings highlight the critical role of layer-number-dependent interactions in MoS2-DAE hybrids, offering valuable insights for the development of advanced photoswitchable devices.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"22 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
