    过度活跃或失调的细胞因子表达是许多急性和慢性炎性疾病的标志。急性或慢性感染都是如此,神经退行性疾病,自身免疫性疾病,心血管疾病,癌症,和其他人。细胞因子如白介素-6(IL-6)是此类炎性疾病的已知治疗靶标和生物标志物。细胞因子检测的平台是,因此,研究和临床应用的理想工具。单壁碳纳米管(SWCNT)是具有近红外荧光的多功能纳米材料,可用作光学传感器的换能器。当用分析物特异性识别元件功能化时,SWCNT发射可以变得对期望的靶敏感和选择性。SWCNT适体传感器易于组装,便宜,和生物相容性。在这项工作中,我们介绍了一种基于SWCNT和IL-6特异性DNA适体的纳米传感器设计。我们首先基于这种简单的直接复合方法评估了几种SWCNT适体构建体,其中适体既溶解SWCNT又赋予对IL-6的敏感性。传感器的检测极限,105ng/mL,位于病理性IL-6水平的相关范围内。在研究传感器动力学后,我们发现在持续3小时的过程的抗原添加数秒内的快速反应。我们发现该传感器构建体是稳定的,并且在IL-6检测期间适体不从纳米管表面移位。最后,我们研究了这种传感器构建体在体外疾病模型中检测细菌脂多糖(LPS)引起的巨噬细胞活化的能力,快速、灵敏地检测巨噬细胞表达的IL-6。我们相信,这种传感器的进一步发展将对急性和慢性炎症性疾病的诊断产生新的影响。除了有助于了解细胞因子在这些疾病中的作用。
    Overactive or dysregulated cytokine expression is a hallmark of many acute and chronic inflammatory diseases. This is true for acute or chronic infections, neurodegenerative diseases, autoimmune diseases, cardiovascular diseases, cancer, and others. Cytokines such as interleukin-6 (IL-6) are known therapeutic targets and biomarkers for such inflammatory diseases. Platforms for cytokine detection are, therefore, desirable tools for both research and clinical applications. Single-walled carbon nanotubes (SWCNT) are versatile nanomaterials with near-infrared fluorescence that can serve as transducers for optical sensors. When functionalized with an analyte-specific recognition element, SWCNT emission may become sensitive and selective toward the desired target. SWCNT-aptamer sensors are easily assembled, inexpensive, and biocompatible. In this work, we introduced a nanosensor design based on SWCNT and a DNA aptamer specific to IL-6. We first evaluated several SWCNT-aptamer constructs based on this simple direct complexation method, wherein the aptamer both solubilizes the SWCNT and confers sensitivity to IL-6. The sensor limit of detection, 105 ng/mL, lies in the relevant range for pathological IL-6 levels. Upon investigation of sensor kinetics, we found rapid response within seconds of antigen addition which continued over the course of 3 h. We found that this sensor construct is stable and the aptamer is not displaced from the nanotube surface during IL-6 detection. Finally, we investigated the ability of this sensor construct to detect macrophage activation caused by bacterial lipopolysaccharides (LPS) in an in vitro model of disease, finding rapid and sensitive detection of macrophage-expressed IL-6. We are confident that further development of this sensor will have novel implications for diagnosis of acute and chronic inflammatory diseases, in addition to contributing to the understanding of the role of cytokines in these diseases.

    据报道,在鉴定助表面活性剂浓度的速率和精度方面取得了显着进步,导致在水性双聚合物相萃取实验中特定的单壁碳纳米管(SWCNT)物种的差异萃取。这些增益通过在SWCNT分散体的自动荧光测量期间连续滴定助表面活性剂和其他溶液组分来实现。所得的荧光与浓度曲线显示强度和波长偏移跃迁可追踪到特定SWCNT结构上吸附的表面活性剂层的性质(n,m)高分辨率的物种和对映异构体水平。滴定法提高的精度和速度解决了以前不可见的复杂性在SWCNT荧光从一个表面活性剂占主导地位的SWCNT界面过渡到另一个。深入了解竞争性交换过程的细节。第一次,我们还证明了表面活性剂转换的竞争过程是方向独立的(可逆的)和无滞后的;后者的数据有效地指定了交换过程时间尺度的上限。将滴定曲线与文献结果进行比较,并对先前不合理的溶液条件进行初始高级参数变化。
    A significant advance in rate and precision of identifying the co-surfactant concentrations leading to differential extraction of specific single-wall carbon nanotube (SWCNT) species in aqueous two-polymer phase extraction experiments is reported. These gains are achieved through continuous titration of co-surfactant and other solution components during automated fluorescence measurements on SWCNT dispersions. The resulting fluorescence versus concentration curves display intensity and wavelength shift transitions traceable to the nature of the adsorbed surfactant layer on specific SWCNT structures at the (n,m) species and enantiomer level at high resolution. The increased precision and speed of the titration method resolve previously invisible complexity in the SWCNT fluorescence during the transition from one surfactant dominating the SWCNT interface to the other, offering insight into the fine details of the competitive exchange process. For the first time, we additionally demonstrate that the competitive process of the surfactant switch is direction independent (reversible) and hysteresis-free; the latter data effectively specifies an upper bound for the time scale of the exchange process. Titration curves are compared to literature results and initial advanced parameter variation is conducted for previously unreasonable to investigate solution conditions.

    许多传热应用,如热交换器,太阳能槽式集热器,以及包括食品加工在内的领域,材料研究,和航空航天工程,利用混合纳米流体。与传统流体相比,混合纳米流体表现出显著增强的导热性。这项工作的目的是探索碳纳米管在具有Dufour和Soret效应的拉伸表面上的磁流体动力学生物对流流动下的流动和传热特征。此外,在存在热辐射和活动微生物的情况下,使用Prandtl流体模型研究了碳纳米管(SWCMT-MWCNT/C2H6O2与SWCMT-MWCNT/C2H6O2-H2O)流动的比较动力学。新颖的功能此外,重点也是检查微生物在混合物基础混合纳米流体的存在。为了检查Prandtl混合纳米流体在拉伸表面上的传热特征,在对边界条件进行建模时考虑了对流加热。已采用适当的相似性变换将维流控制方程转换为无量纲方程,并使用有效的方法获得了问题的解决方案,在MATLAB中准确和节省时间的bvp-4c技术。速度,温度,浓度和微生物谱已被证明在各种无量纲参数如倾斜磁化的不同影响下,混合对流,Dufour效应,Soret效应,热辐射效应,和生物对流刘易斯数。已经观察到提高磁化强度值(0.5≤M≤4),与碳纳米管的混合基础工作流体相比,混合对流(0.01≤λ≤0.05)和倾角(0°≤α≤180°)迅速增强了基于乙二醇的Prandtl杂化纳米流体(SWCMT-MWCNT/C2H6O2)的流体运动。SWCMT-MWCNT/C2H6O2-H2O)。提高热辐射(0.1≤Rd≤1.7)和Dufour数(0.1≤Du≤0.19)值可改善温度分布。此外,目前的结果与现有文献对皮肤摩擦结果有很好的一致性.
    Numerous heat transfer applications, such as heat exchangers, solar trough collectors, and fields including food processing, material research, and aerospace engineering, utilize hybrid nanofluids. Compared to conventional fluids, hybrid nanofluids exhibit significantly enhanced thermal conductivity. The aim of this work is to explore flow and heat transmission features under of magneto-hydrodynamic bioconvective flow of carbon nanotubes over the stretched surface with Dufour and Soret effects. Additionally, comparative dynamics of the carbon nanotubes (SWCMT - MWCNT/C2H6O2 with SWCMT - MWCNT/C2H6O2 - H2O) flow using the Prandtl fluid model in the presence of thermal radiation and motile microorganisms has been investigated. Novel feature Additionally, the focus is also to examine the presence of microorganisms in mixture base hybrid nanofluid. To examine heat transfer features of Prandtl hybrid nanofluid over the stretched surface convective heating is taken into consideration while modeling the boundary conditions. Suitable similarity transform has been employed to convert dimensional flow governing equations into dimensionless equations and solution of the problem has been obtained using effective, accurate and time saving bvp-4c technique in MATLAB. Velocity, temperature, concentration and microorganisms profiles have been demonstrated graphically under varying impact of various dimensionless parameters such as inclined magnetization, mixed convection, Dufour effect, Soret effect, thermal radiation effect, and bioconvection lewis number. It has been observed that raising values of magnetization (0.5 ≤ M ≤ 4), mixed convection (0.01 ≤ λ ≤ 0.05) and inclination angle (0° ≤ α ≤ 180°) enhance fluid motion rapidly in Ethylene glycol based Prandtl hybrid nanofluid (SWCMT - MWCNT/C2H6O2) when compared with mixture base working fluid of carbon nanotubes SWCMT - MWCNT/C2H6O2 - H2O). Raising thermal radiation (0.1 ≤ Rd ≤ 1.7) and Dufour number (0.1 ≤ Du ≤ 0.19) values improves temperature profile. Moreover, a good agreement has been found between the current outcome and existing literature for skin friction outcomes.

    已知白细胞介素-6(IL-6)在炎症性疾病如心血管疾病的进展中起关键作用。癌症,脓毒症,病毒感染,神经系统疾病,和自身免疫性疾病。新兴的诊断和预后工具,比如光学纳米传感器,部分由于蛋白质电晕的形成,在临床上经历了翻译方面的挑战,抑制其选择性和灵敏度。为了解决这个问题,我们探索了在非共价表面钝化中用作试剂的几类生物分子的合理筛选,作为筛选非特异性蛋白质干扰的策略。来自该筛选的结果应用于通过荧光抗体缀合的单壁碳纳米管(SWCNT)基纳米传感器检测IL-6。IL-6纳米传感器在用聚合物钝化后表现出高灵敏度和特异性的检测,聚-l-赖氨酸,如在25至25,000pg/mL的临床相关范围内检测人血清中的IL-6所证明的,表现出比现有的抗体缀合的SWCNT传感器低3个数量级以上的检测极限。这项工作具有在临床环境中快速和高度敏感地检测IL-6的潜力,并将其应用于其他细胞因子或疾病特异性生物标志物。
    Interleukin-6 (IL-6) is known to play a critical role in the progression of inflammatory diseases such as cardiovascular disease, cancer, sepsis, viral infection, neurological disease, and autoimmune diseases. Emerging diagnostic and prognostic tools, such as optical nanosensors, experience challenges in translation to the clinic in part due to protein corona formation, dampening their selectivity and sensitivity. To address this problem, we explored the rational screening of several classes of biomolecules to be employed as agents in noncovalent surface passivation as a strategy to screen interference from nonspecific proteins. Findings from this screening were applied to the detection of IL-6 by a fluorescent-antibody-conjugated single-walled carbon nanotube (SWCNT)-based nanosensor. The IL-6 nanosensor exhibited highly sensitive and specific detection after passivation with a polymer, poly-l-lysine, as demonstrated by IL-6 detection in human serum within a clinically relevant range of 25 to 25,000 pg/mL, exhibiting a limit of detection over 3 orders of magnitude lower than prior antibody-conjugated SWCNT sensors. This work holds potential for the rapid and highly sensitive detection of IL-6 in clinical settings with future application to other cytokines or disease-specific biomarkers.

    本研究提出了用SWCNT墨水对丝织物进行功能化。第一步是在丝织物上形成聚多巴胺(PDA)薄涂层以允许SWCNT的有效结合。PDA的形成是通过在碱性条件下多巴胺的聚合直接在织物上进行的。通过使用浸涂方法,用不同SWCNT浓度的SWCNT墨水将丝绸/PDA织物官能化。IR和拉曼分析表明,在官能化过程之后,丝素蛋白的主要β-折叠结构保持不变。耐热性甚至略有改善。由于PDA和SWCNT油墨中的表面活性剂的影响,疏水性丝织物在功能化后变得亲水。油墨显著改变了丝织物的电性能,从绝缘到导电。体积电阻变化了九个数量级,从2.4×1012Ω到2.3×103Ω,为0.12wt。%的SWCNT。表面电阻变化了七个数量级,从2.1×1012Ω到2.4×105Ω,0.17wt。%的SWCNT。体积和表面电阻阈值被确定为约0.05重量%。%和0.06重量%。%,分别。渗滤阈值的低值表明有效的功能化,用高质量的墨水促进通过SWCNT的渗透路径的形成和PDA接头的影响。
    This study presents the functionalization of silk fabric with SWCNT ink. The first step was the formation of a polydopamine (PDA) thin coating on the silk fabric to allow for effective bonding of SWCNTs. PDA formation was carried out directly on the fabric by means of polymerization of dopamine in alkali conditions. The Silk/PDA fabric was functionalized with SWCNT ink of different SWCNT concentrations by using the dip-coating method. IR and Raman analyses show that the dominant β-sheet structure of silk fibroin after the functionalization process remains unchanged. The heat resistance is even slightly improved. The hydrophobic silk fabric becomes hydrophilic after functionalization due to the influence of PDA and the surfactant in SWCNT ink. The ink significantly changes the electrical properties of the silk fabric, from insulating to conductive. The volume resistance changes by nine orders of magnitude, from 2.4 × 1012 Ω to 2.3 × 103 Ω for 0.12 wt.% of SWCNTs. The surface resistance changes by seven orders of magnitude, from 2.1 × 1012 Ω to 2.4 × 105 Ω for 0.17 wt.% of SWCNTs. The volume and surface resistance thresholds are determined to be about 0.05 wt.% and 0.06 wt.%, respectively. The low value of the percolation threshold indicates efficient functionalization, with high-quality ink facilitating the formation of percolation paths through SWCNTs and the influence of the PDA linker.

    面对全球范围内不断升级的病毒威胁,开发用于快速病毒检测的高效传感器元件从未如此重要。传统的即时护理(POC)传感器由于其对脆弱的生物受体的依赖和对病毒株的有限适应性而挣扎。在这项研究中,我们介绍了使用近红外(NIR)荧光单壁碳纳米管(SWCNT)与聚(乙二醇)(PEG)-磷脂(PEG-脂质)阵列官能化的无受体病毒识别的纳米传感器设计。纳米传感器阵列的三维(3D)电晕接口能够选择性和灵敏地检测多种病毒,包括埃博拉病毒,拉萨,H3N2,H1N1,中东呼吸综合征(MERS),严重急性呼吸综合征冠状病毒1(SARS-CoV-1),和SARS-CoV-2,即使没有任何生物受体。PEG-脂质成分,设计考虑链条长度,脂肪酸饱和度,分子量,和端基部分,允许病毒识别能力的精确量化。阵列的高通量自动化筛选表明PEG-脂质/SWCNT3D电晕界面的物理化学性质如何与病毒检测效率相关。利用分子动力学和AutoDock模拟,我们研究了PEG-脂质组分对三维电晕界面形成的影响,例如表面覆盖率和流体动力学半径以及基于化学势的特定分子相互作用。我们的发现不仅增强了各种抗原的检测特异性,而且还加速了传感器材料的开发,以迅速识别和响应新出现的抗原威胁。
    Facing the escalating threat of viruses worldwide, the development of efficient sensor elements for rapid virus detection has never been more critical. Traditional point-of-care (POC) sensors struggle due to their reliance on fragile biological receptors and limited adaptability to viral strains. In this study, we introduce a nanosensor design for receptor-free virus recognitions using near-infrared (NIR) fluorescent single-walled carbon nanotubes (SWCNTs) functionalized with a poly(ethylene glycol) (PEG)-phospholipid (PEG-lipid) array. Three-dimensional (3D) corona interfaces of the nanosensor array enable selective and sensitive detection of diverse viruses, including Ebola, Lassa, H3N2, H1N1, Middle East respiratory syndrome (MERS), severe acute respiratory syndrome coronavirus 1 (SARS-CoV-1), and SARS-CoV-2, even without any biological receptors. The PEG-lipid components, designed considering chain length, fatty acid saturation, molecular weight, and end-group moieties, allow for precise quantification of viral recognition abilities. High-throughput automated screening of the array demonstrates how the physicochemical properties of the PEG-lipid/SWCNT 3D corona interfaces correlate with viral detection efficiency. Utilizing molecular dynamics and AutoDock simulations, we investigated the impact of PEG-lipid components on 3D corona interface formation, such as surface coverage and hydrodynamic radius and specific molecular interactions based on chemical potentials. Our findings not only enhance detection specificity across various antigens but also accelerate the development of sensor materials for promptly identifying and responding to emerging antigen threats.

    以不影响sp2碳骨架的稳健方式官能化单壁碳纳米管(SWCNT)是相当大的研究挑战。在这里,我们描述了带正电荷的大环的三碘化物盐如何不仅可以用于从外部官能化SWCNT,但同时从内部。我们在水性溶剂中使用二硫化物交换以最大化疏溶剂效应,并因此实现高度的大环固定。通过拉曼光谱表征,EDX-STEM和HR-TEM清楚地表明,偶然地,这种湿化学官能化方案也导致多碘化物链包封在纳米管内。由此产生的三壳复合材料具有氧化还原活性,并经历了静电作用的有趣相互作用,疏溶剂和机械效应可能对储能应用感兴趣。
    Functionalizing single-walled carbon nanotubes (SWCNTs) in a robust way that does not affect the sp2 carbon framework is a considerable research challenge. Here we describe how triiodide salts of positively charged macrocycles can be used not only to functionalize SWCNTs from the outside, but simultaneously from the inside. We employed disulfide exchange in aqueous solvent to maximize the solvophobic effect and therefore achieve a high degree of macrocycle immobilization. Characterization by Raman spectroscopy, EDX-STEM and HR-TEM clearly showed that serendipitously this wet-chemical functionalization procedure also led to the encapsulation of polyiodide chains inside the nanotubes. The resulting three-shell composite materials are redox-active and experience an intriguing interplay of electrostatic, solvophobic and mechanical effects that could be of interest for applications in energy storage.

    目的:测量静脉血浆扑热息痛浓度是耗时和耗费资源的。我们旨在验证用于快速测定对乙酰氨基酚浓度的新型电化学护理点(POC)测定。
    方法:12名健康志愿者口服1克扑热息痛,并在12小时内对毛细血管全血(POC)的浓度进行了10次分析,静脉血浆(高效液相色谱串联质谱(HPLC-MS/MS)),和干毛细血管血(HPLC-MS/MS)。
    结果:在浓度>30μM时,与静脉血浆和毛细血管血HPLC-MS/MS相比,POC显示20%(95%的一致性极限[LOA]-22至62)和7%(95%LOA-23至38)的向上偏差,分别。对乙酰氨基酚消除阶段的平均浓度之间没有显着差异。
    结论:与静脉血浆HPLC-MS/MS相比,POC的向上偏差可能是由于毛细血管血液中对乙酰氨基酚的浓度高于静脉血浆和个别传感器的故障。新的POC方法是扑热息痛浓度分析的有前途的工具。
    Measuring venous plasma paracetamol concentrations is time- and resource-consuming. We aimed to validate a novel electrochemical point-of-care (POC) assay for rapid paracetamol concentration determinations.
    Twelve healthy volunteers received 1 g oral paracetamol, and its concentrations were analysed 10 times over 12 h for capillary whole blood (POC), venous plasma (high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS)), and dried capillary blood (HPLC-MS/MS).
    At concentrations >30 μM, POC showed upward biases of 20% (95% limits of agreement [LOA] -22 to 62) and 7% (95% LOA -23 to 38) compared with venous plasma and capillary blood HPLC-MS/MS, respectively. There were no significant differences between mean concentrations for the paracetamol elimination phase.
    Upward biases in POC compared with venous plasma HPLC-MS/MS were likely due to higher paracetamol concentrations in capillary blood than in venous plasma and to faulty individual sensors. The novel POC method is a promising tool for paracetamol concentration analysis.

    在本研究中,通过熔融混合制备聚(甲基丙烯酸甲酯)(PMMA)/单壁碳纳米管(SWCNT)复合材料,以实现合适的SWCNT分散和分布以及低电阻率,由此将SWCNT直接并入方法与母料稀释进行比较。发现电渗透阈值为0.05-0.075wt%,迄今为止报道的熔融混合PMMA/SWCNT复合材料的最低阈值。研究了转速和SWCNT掺入PMMA基质的方法对电性能和SWCNT宏观分散的影响。发现增加旋转速度改善了宏观分散和电导率。结果表明,通过高转速直接掺入可以制备具有低渗透阈值的导电复合材料。与直接并入SWCNT相比,母料方法导致更高的电阻率值。此外,研究了PMMA/SWCNT复合材料的热行为和热电性能。对于高达5wt%SWCNT的复合材料,塞贝克系数从35.8µV/K到53.4µV/K不等。
    In the present study, Poly(methyl methacrylate) (PMMA)/single-walled carbon nanotubes (SWCNT) composites were prepared by melt mixing to achieve suitable SWCNT dispersion and distribution and low electrical resistivity, whereby the SWCNT direct incorporation method was compared with masterbatch dilution. An electrical percolation threshold of 0.05-0.075 wt% was found, the lowest threshold value for melt-mixed PMMA/SWCNT composites reported so far. The influence of rotation speed and method of SWCNT incorporation into the PMMA matrix on the electrical properties and the SWCNT macro dispersion was investigated. It was found that increasing rotation speed improved macro dispersion and electrical conductivity. The results showed that electrically conductive composites with a low percolation threshold could be prepared by direct incorporation using high rotation speed. The masterbatch approach leads to higher resistivity values compared to the direct incorporation of SWCNTs. In addition, the thermal behavior and thermoelectric properties of PMMA/SWCNT composites were studied. The Seebeck coefficients vary from 35.8 µV/K to 53.4 µV/K for composites up to 5 wt% SWCNT.
