Abstract This review presents the essential brief annals, crucial analytics, precise applications and noteworthy implications of design of experiments which enrouted to liquid chromatography (LC) in the midst of utmost focus on high-performance liquid-chromatography (HPLC) and broadened its impressions on allied techniques in pharmaceutical analysis. Being most widely applied statistical methodologies for such purpose, its use was started in 1970 and heightened after Fischer’s precious input in 1981. The persistent use of statistical approaches one after another led to the efficient attention of pharmaceutical analysts. Hence, in order to fine-tune the trail impressed by the cumulative trends, the use of statistical designs in HPLC analysis has been reviewed and efforts were made to recognize its relative impact and corresponding future prospects. Applications of precise methodologies have been reassessed with respect to the need established by recent regulatory perspectives with a fanatical and the consequent stance on prominent historical advancements and concrete purposes. An effort was also made to state an arbitrary classification of diverse design types and succinct line of application in LC and associated analyses.
摘要:本文介绍了在高效液相色谱(HPLC)的高度关注中引入液相色谱(LC)的基本简史、关键分析、精确应用和值得注意的实验设计的意义,并扩大了其对药物分析相关技术的印象。作为这方面应用最广泛的统计方法,它的使用始于1970年,并在1981年费舍尔的宝贵投入后得到加强。一个接一个的统计方法的持续使用导致了药物分析人员的有效关注。因此,为了对累积趋势所留下的痕迹进行微调,本文回顾了统计设计在HPLC分析中的应用,并努力认识其相对影响和相应的未来前景。对精确方法的应用进行了重新评估,考虑到最近的监管观点所确立的需要,以及对突出的历史进步和具体目的的狂热和随之而来的立场。我们还努力对LC和相关分析中的不同设计类型和简洁的应用程序进行了任意分类。

Abstract The attractive structural and mechanical properties of cellulose substrates (paper, cloth, and thread), including passive fluid transport, biocompatibility, durability, and flexibility, have attracted researchers in the past few decades to explore them as alternative microfluidic platforms. The incorporation of electrochemical (EC) sensing broadened their use for applications such as clinical diagnosis, pharmaceutical chemical analyses, food quality, and environmental monitoring. This article provides a review on the microfluidic devices constructed on paper, cloth, and thread substrates. It begins with an overview on paper-based microfluidic devices, followed by an in-depth review on the various applications of EC detection incorporated on paper-based microfluidic devices reported to date. The review on paper-based microfluidic devices attempts to convey a few perspective directions that cloth- and thread-based microfluidic devices may take in its development. Finally, the research efforts on the development and evaluation, as well as current limitations of cloth- and thread-based microfluidic devices are discussed. Microfluidic devices constructed on paper, cloth, and thread substrates are still at an early development stage (prototype) requiring several improvements in terms of fabrication, analytical techniques, and performance to become mature platforms that can be adapted and commercialized as real world products. However, they hold a promising potential as wearable devices.
纤维素基质(纸、布和线)具有引人注目的结构和机械性能,包括被动流体输送、生物相容性、耐久性和柔韧性,在过去的几十年里吸引了研究人员探索它们作为替代微流体平台。电化学(EC)传感的结合扩大了它们在临床诊断、药物化学分析、食品质量和环境监测等应用中的应用。本文综述了基于纸、布和线的微流控装置的研究进展。首先概述了基于纸的微流控装置,然后深入回顾了迄今为止报告的基于纸的微流控装置上的EC检测的各种应用。本文对纸基微流控器件的研究进展进行了综述,并对布基和线基微流控器件的发展方向进行了展望。最后,讨论了基于布和线的微流控装置的发展和评价,以及目前的局限性。在纸、布和线基板上构建的微流体装置仍处于早期开发阶段(原型),需要在制造、分析技术和性能方面进行几次改进,才能成为成熟的平台,可以作为现实世界的产品进行调整和商业化。然而,它们作为可穿戴设备具有很大的潜力。

Abstract In recent decades, there has been a substantial increase in the consumption of fruits and vegetables due to their nutritional properties since they are known as sources of vitamins, minerals, fiber, and antioxidants. Moreover, a substantial growth in fresh-cut fruits and vegetables has been noticed because of their ease to use; in fact changes in human life styles have led consumers to move towards ready-to-eat products. In this context, product quality must be preserved at each step of product handling, processing, and storage, and therefore rapid methods should be available to provide useful information in process management. In this review an overview of the applications of widely used non-destructive techniques, namely, electronic nose and visible/near infrared spectroscopy, for measuring quality of fruits and vegetables is presented. A brief description of spectroscopic and electronic devices and a selection of applications are provided. Future perspectives about the simplification/application of these non-destructive techniques are finally explored.
近几十年来,由于水果和蔬菜的营养特性,它们被认为是维生素、矿物质、纤维和抗氧化剂的来源,因此水果和蔬菜的消费量大幅增加。此外,人们注意到鲜切水果和蔬菜的大量增长,因为它们易于使用;事实上,人类生活方式的变化导致消费者转向即食产品。在这种情况下,必须在产品处理、加工和储存的每个步骤中保持产品质量,因此应该有快速的方法来提供过程管理中有用的信息。本文综述了近年来广泛应用的无损检测技术,即电子鼻和可见/近红外光谱技术在果蔬品质检测中的应用。提供了光谱和电子设备的简要描述以及应用的选择。最后对这些非破坏性技术的简化和应用进行了展望。

Abstract Metal ions play critical roles in numerous fundamental life processes. Hence, there is a great need to effectively monitor and image metal ions. Fluorescent probes are one of the most effective methods for measuring metal ions. In general, according to the different recognition mechanisms of fluorescent probes, they can be divided into two categories: reversible probes and irreversible probes. Among the various fluorophores, rhodamine and fluorescein, as the typical representatives of xanthene, have been paid much attention in biological imaging due to their high absorption coefficient, high fluorescence quantum yield, and water solubility. This review highlights the recent advances on chelation-based xanthene fluorescent probes that have been used for detecting metal ions. The focus has been on the design strategies to improve the selectivity and sensitivity of fluorescent probes by introducing different recognition moieties. Meanwhile, their recognition mechanism and applications are particularly highlighted.
金属离子在许多基本生命过程中起着至关重要的作用。因此,非常需要对金属离子进行有效的监测和成像。荧光探针是测量金属离子最有效的方法之一。一般来说,根据荧光探针识别机制的不同,可将其分为可逆探针和不可逆探针两大类。在各种荧光团中,罗丹明和荧光素作为杂蒽的典型代表,因其具有高吸收系数、高荧光量子产率和水溶性等特点,在生物成像领域受到了广泛的关注。本文综述了近年来基于螯合的杂蒽荧光探针用于检测金属离子的研究进展。重点是通过引入不同的识别基团来提高荧光探针的选择性和灵敏度的设计策略。同时,重点介绍了它们的识别机制和应用。

Abstract Recently, numerous luminescent molecular thermometers that exhibit temperature-dependent emission properties have been developed to measure the temperatures of tiny spaces. Intracellular temperature is the most interesting and exciting applications of luminescent molecular thermometers because this temperature is assumed to be correlated with all cell events, such as cell division, gene expression, enzyme reaction, metabolism, and pathogenesis. Among the various types of temperature-dependent emission parameters of luminescent molecular thermometers, the emission intensity ratio at two different wavelengths is suitable for accurate and accessible intracellular temperature measurements. In this review article, luminescent molecular thermometers that exhibit a temperature-dependent emission intensity ratio in living cells are summarized, and current progress in intracellular thermometry is outlined.

Prosperity to challenges: recent approaches in SERS substrate fabrication 繁荣到挑战:SERS基板制造的最新方法

Abstract Surface-enhanced Raman spectroscopy (SERS) is a highly promising analytical technique that has been widely applied in health and environment monitoring. As a vibrational spectroscopic tool, its fingerprint spectrum contains abundant molecular information, and the greatly enhanced signal can be used to detect analytes at extremely low concentration, even down to the single molecule level. Because water molecules give very weak Raman response, Raman spectroscopy has also been applied for in situ monitoring of targets in solution. However, the Raman signal of an analyte could only be enhanced when it is in proximity to the SERS substrate, which enhances the signal depending on the shape, size, and orientation of the particles constituting the substrate. Further, when using the method for the detection of various analytes, it is necessary to functionalize the SERS substrates, with recognition ligands and encapsulation with a suitable shell among others. Hence, the fabrication of suitable substrates is a basic step in SERS-related research. Tremendous effort has been expended in the last decade in this area, resulting in the development of substrates with unique properties. In this review, we will introduce recent achievements in SERS substrate fabrication based on their structural features. Synthesized nanoparticles, two-dimensional planar substrates, and three-dimensional substrates with effective volume will be discussed in the context of their synthesis strategies along with their characteristic properties. In the future, with further improvement in SERS substrates, the applicability of SERS for detecting a range of analytes in complex environment will become possible.
摘要表面增强拉曼光谱(SERS)是一种非常有前途的分析技术,在健康和环境监测中得到了广泛应用。作为一种振动光谱工具,其指纹图谱包含了丰富的分子信息,大大增强的信号可以用于检测极低浓度的分析物,甚至可以检测到单分子水平。由于水分子的拉曼响应非常弱,拉曼光谱也被应用于溶液中目标的原位监测。然而,分析物的拉曼信号只有在接近SERS衬底时才能增强,这取决于构成衬底的颗粒的形状、大小和取向。此外,当使用该方法检测各种分析物时,需要对SERS底物进行功能化,包括识别配体和用合适的外壳封装等。因此,制造合适的衬底是sers相关研究的基本步骤。在过去的十年中,在这一领域花费了巨大的努力,从而开发出具有独特性能的基材。在这篇综述中,我们将根据SERS衬底的结构特点,介绍近年来在SERS衬底制造方面的进展。合成的纳米颗粒、二维平面底物和三维有效体积底物将在其合成策略及其特征性质的背景下进行讨论。在未来,随着SERS底物的进一步改进,SERS在复杂环境中检测一系列分析物的适用性将成为可能。

Abstract Dysregulation of gene expression mechanisms has been observed in many tumors, making their analysis of utmost importance. These mechanisms include DNA methylation, an epigenetic mechanism in which 5-carbon of cytosine becomes methylated, leading to gene silencing, and action of short RNA molecules called microRNAs, which regulate protein synthesis at post-transcriptional level by binding to mRNAs. In this review, we describe major roles of both mechanisms in carcinogenesis, offer an overview of currently used methods for their analysis, and summarize most recent advances in electrochemical-based assays and strategies. Advantages of electrochemistry, including favorable cost, time of experiment, or simple instrumentation, are highlighted, along with current challenges that need to be addressed prior to successful application into clinical routine.

Abstract Human body odor is a unique identity feature of individual as well as an established composite of numerous volatile organic compounds (VOCs) belonging to significant chemical classes. Several analytical methods have been used in the characterization of human body odor in order to recognize the chemical composition of VOCs in medical, forensic, and biometric applications. Besides, real-time sensing systems (based on the chemical sensors) are being researched and developed for qualitative and quantitative recognition of VOCs in body odor. The present review focuses the state-of-the-art research outcomes related to the characterization of human body odor with the objective to identify the VOCs belonging to aldehyde class. Furthermore, the application of chemical sensors in past studies for the detection of aldehydes besides other chemical compounds in body odor is summarized and the significance of aldehydes detection in different applications is discussed.
人体气味是个体独特的身份特征,也是属于重要化学类别的众多挥发性有机化合物(VOCs)的既定复合物。为了在医学、法医和生物识别应用中识别挥发性有机化合物的化学成分,已经使用了几种分析方法来表征人体气味。此外,基于化学传感器的实时传感系统正在研究和开发,用于定性和定量识别体味中的挥发性有机化合物。本文综述了人体气味表征的最新研究成果,目的是识别醛类挥发性有机化合物。总结了化学传感器在检测体臭中醛类及其他化合物方面的应用研究,并讨论了醛类检测在不同应用中的意义。
