Gelatin (GE) is a versatile biopolymer with many valuable properties, particularly in the context of food packaging (FPack). Its biodegradability, biocompatibility, and ability to form porous structures make it ideal for various applications. This review examines the applications of electrospun GE-based nanofibers (EGFs) and their recent advances in FPack. The majority of EGFs are determined to be biodegradable and biocompatible, with the ability to form a highly porous structure with outstanding characteristics, making them appropriate for a broad range of applications, including FPack. However, native GE has limitations, such as sensitivity to moisture, which can restrict its use in certain applications. To address these limitations, researchers are exploring ways to enhance the properties of GE-based materials. EGFs are produced with a variety of natural and synthetic ingredients to increase their physical, mechanical, elastic, water resistance, vapor barrier, UV-blocking, and thermal stability properties. Furthermore, EGFs have antimicrobial and antioxidant properties that help to extend the shelf life of many food products. The prospective uses, challenges, and limitations of EGFs in FPack are also addressed. Overall, EGFs show promise as a sustainable and effective packaging material, but further research is needed to optimize their properties and ensure their safety for use in FPack.
明胶(GE)是一种多功能生物聚合物,具有许多有价值的特性,特别是在食品包装(FPack)的背景下。它的生物可降解性、生物相容性和形成多孔结构的能力使其成为各种应用的理想材料。本文综述了电纺ge基纳米纤维(EGFs)在FPack中的应用及其最新进展。大多数egf被确定为可生物降解和生物相容性,具有形成具有突出特性的高多孔结构的能力,使其适用于包括FPack在内的广泛应用。然而,原生GE有其局限性,比如对水分的敏感性,这可能会限制其在某些应用中的使用。为了解决这些限制,研究人员正在探索增强ge基材料性能的方法。egf是由多种天然和合成成分制成的,以提高其物理、机械、弹性、耐水性、蒸汽阻隔性、紫外线阻隔性和热稳定性。此外,EGFs具有抗菌和抗氧化特性,有助于延长许多食品的保质期。还讨论了FPack中egf的潜在用途、挑战和局限性。总体而言,egf有望成为一种可持续和有效的包装材料,但需要进一步的研究来优化其性能并确保其在FPack中使用的安全性。

Based on interface science, research and application analysis are carried out on the interface action mechanism of resin-based plugging agents in the field of formation plugging. This paper outlines the classification, structural characterization, and performance evaluation of resin-based plugging agents. It reviews the research progress and current applications of thermosetting, swelling filling, temperature-sensitive adhesive, and composite resins in the plugging engineering field, elucidating their interfacial mechanisms, which include: dynamic crosslinking curing at the fluid-formation interface, adaptive swelling-filling at the interface of plugging agents, interfacial adhesion enhancement induced by thermal response, and multiphase composite synergism at complex interfaces. The paper also proposes future directions and application prospects for resin plugging agents. Current technologies face challenges such as interfacial adaptability under extreme environments in ultra-deep formations, ecological safety of interface interactions, and accuracy of intelligent interfacial response. Future research should focus on controllable crosslinking for thermosetting resins to optimize interfacial curing, intelligent response for swelling filling resins to enhance interface adaptation, interface strengthening for temperature-sensitive adhesive resin (TSAR) to improve adhesion stability, and multiphase synergy with eco-design for composite systems to regulate complex interfacial behaviors, providing efficient and environmentally friendly solutions for malignant lost circulation control.

Fluorescent molecularly imprinted polymers (FMIPs) have emerged as promising biomedical tools due to their high selectivity, stability, and tunable fluorescent properties. Their distinct combination of selective molecular recognition and sensitive optical signaling makes them appropriate for a variety of diagnostic and sensing applications especially for healthcare monitoring. This review summarizes recent advances in FMIPs synthesis strategies, focusing on innovative polymerization methods such as controlled/living radical polymerization and green synthesis approaches that address key challenges in reproducibility, scalability, and environmental sustainability. Advances in polymer design, functional monomer selection, and nanofabrication techniques have considerably increased FMIP sensitivity and specificity for critical biomolecular sensing applications. These smart materials contain extremely selective binding sites that resemble natural receptors, allowing for precise biomolecule detection in applications such as biosensing, bioimaging, and medication administration. The integration of modern fluorescence-based detection techniques improves their ability to monitor biological processes in real time with high precision. This comprehensive review also addresses the most challenges of FMIPs, such as largescale synthesis, biocompatibility, template removal and signal stability. Finally, future directions for developing FMIPs for personalized medicine and next-generation POC diagnostics are discussed.

The diversity of chiral molecules is due to their unique asymmetric structure. Although the physical and chemical properties of enantiomers may be similar, their optical and biological activities are often very different or even opposite. From the selection of chiral molecules in life to the design of modern materials with specific chiral functions, chirality has always been a long-standing research topic. Every exploration of chiral science promotes human understanding of the world and the advancement of science and technology. The chiral-induced spin-selective (CISS) effect is a breakthrough in the study of chiral molecules in recent years, which reveals the relationship between chiral molecules and electron spins from a unique perspective. Due to the CISS effect, chiral materials selectively filter electrons with a specific spin direction (spin polarization), thereby achieving spin regulation without the need for an external magnetic field. Therefore, the CISS effect provides a new exploration space for chiral recognition, asymmetric synthesis, origin of life, chiral electrocatalysis, and chemical reaction monitoring. This review summarizes the basic principles, development history, theoretical basis, research status and development trends of the CISS effect in chiral materials, and prospects the research status of the CISS effect in related fields.
手性分子的多样性是由于其独特的不对称结构。虽然对映体的物理和化学性质可能相似,但它们的光学和生物活性往往非常不同甚至相反。从生活中手性分子的选择到具有特定手性功能的现代材料的设计,手性一直是一个长期存在的研究课题。手性科学的每一次探索都促进了人类对世界的认识和科学技术的进步。手性诱导自旋选择效应(CISS)是近年来手性分子研究的一个突破,它从一个独特的角度揭示了手性分子与电子自旋之间的关系。由于CISS效应,手性材料选择性地过滤具有特定自旋方向(自旋极化)的电子,从而在不需要外部磁场的情况下实现自旋调节。因此,CISS效应为手性识别、不对称合成、生命起源、手性电催化、化学反应监测等提供了新的探索空间。综述了手性材料中CISS效应的基本原理、发展历史、理论基础、研究现状和发展趋势,并对CISS效应在相关领域的研究现状进行了展望。

Nanotechnology has been widely utilized to enhance the intestinal absorption of natural bioactive compounds (BCs). However, the complicated and dynamic environment in the gastrointestinal tract (GIT) – characterized by digestive enzymes, mucus matrix, epithelial cell layer, and extensive metabolic activity – presents notable challenges to the oral delivery of BCs. To address these limitations, nanocarriers based on enzymatically hydrolyzed food protein polypeptides (EH-FPPs) have been developed, which exhibit high biocompatibility, loading capacity, and capacity to overcome different absorption barriers. This review provides a comprehensive summary of recent advancements in EH-FPP-assembled nanocarriers, including their self-assembly mechanisms, supramolecular structures, and loading approaches for natural BCs. Besides, it elucidates the how these nanocarriers enhance the intestinal absorption of BCs from the perspectives of controlled release, mucus penetration, transcytosis, and paracellular transport. Furthermore, it critically assesses the role of these nanocarriers in improving the overall bioavailability and therapeutic efficacy of encapsulated BCs, while also addressing their current limitations and future research directions. This review seeks to elucidate the complex relationships between the self-assembly process, multi-scale structure, and GIT fate of EH-FPP-based vehicles, which highlights their potential as advanced BC delivery systems for precision nutrition and individualized health.
纳米技术已被广泛应用于促进天然生物活性化合物(bc)的肠道吸收。然而,消化道(GIT)复杂而动态的环境——以消化酶、粘液基质、上皮细胞层和广泛的代谢活动为特征——给口服给药带来了显著的挑战。为了解决这些限制,基于酶水解食品蛋白多肽(EH-FPPs)的纳米载体被开发出来,它具有高的生物相容性、负载能力和克服不同吸收障碍的能力。本文综述了eh - fpp组装纳米载体的最新进展,包括其自组装机制、超分子结构和天然bc的装载方法。并从控释、黏液渗透、胞吞作用和细胞旁转运等方面阐述了这些纳米载体如何增强bc的肠道吸收。此外,它批判性地评估了这些纳米载体在提高包封bc的整体生物利用度和治疗效果方面的作用,同时也指出了它们目前的局限性和未来的研究方向。本文旨在阐明eh - fpp载体的自组装过程、多尺度结构和GIT命运之间的复杂关系,强调其作为精密营养和个性化健康的先进BC输送系统的潜力。

The bacterial cell membrane is a structurally essential and relatively accessible target for several antimicrobial agents, including daptomycin, polymyxins, antimicrobial peptides, and polymers. These compounds are often effective against multidrug-resistant bacteria and are considered last resort treatments. While initially considered less prone to resistance development, accumulating evidence shows that bacteria can adapt through various mechanisms – often involving alterations in membrane composition and biophysical properties. Reported resistance mechanisms include changes in phospholipid composition, lipid A structure, membrane fluidity, surface charge, and microdomain organization. Advances in analytical methodologies – including liquid and gas chromatography, capillary electrophoresis, mass spectrometry, and fluorescence-based techniques—have enabled increasingly precise characterization of these adaptations. In this review, we outline membrane remodeling strategies associated with resistance in both Gram-positive and Gram-negative bacteria and provide an overview of analytical methods commonly employed to study these changes. These insights highlight the growing relevance of membrane-level adaptations in antimicrobial resistance and underscore the need for further research using modern lipidomic and biophysical tools.
细菌细胞膜是一些抗菌剂的结构必需和相对容易获得的靶点,包括达托霉素、多粘菌素、抗菌肽和聚合物。这些化合物通常对耐多药细菌有效,被认为是最后的治疗手段。虽然最初被认为不太容易产生耐药性,但越来越多的证据表明,细菌可以通过各种机制适应——通常涉及改变膜的组成和生物物理特性。已报道的抗性机制包括磷脂组成、脂质A结构、膜流动性、表面电荷和微域组织的变化。分析方法的进步——包括液相和气相色谱、毛细管电泳、质谱分析和基于荧光的技术——使得对这些适应性的描述越来越精确。在这篇综述中,我们概述了与革兰氏阳性和革兰氏阴性细菌耐药相关的膜重塑策略,并概述了研究这些变化的常用分析方法。这些见解强调了膜水平适应在抗菌素耐药性中的日益增长的相关性,并强调了使用现代脂质组学和生物物理工具进行进一步研究的必要性。

Solid-state nanopores have emerged as transformative tools for single-molecule detection and analysis of DNA, RNA, and proteins in the field of biotechnology. This review focuses on controlled dielectric breakdown (CBD), an in-situ fabrication technique that utilizes electric fields to induce membrane dielectric breakdown, offering low-cost, scalable nanopore fabrication in insulating materials. The principles of dielectric breakdown mechanisms, integrating thermal, electrical, and chemical mechanisms, are analyzed, highlighting the critical role of parameters such as electric field intensity, material dielectric properties, and solid-liquid interface dynamics in enabling precise control over nanopore fabrication. Unlike expensive lithography methods, CBD avoids complex ex situ processes, enabling real-time monitoring via leakage currents. Key advancements in strategies for localized area thinning and laser-assisted pre-damage, micropipette-based localized confined electrolyte, and atomic force microscope tip-induced localized electric field have addressed the traditional CBD's stochasticity. These strategies enable deterministic sub-2 nm nanopore formation with tunable morphology.

Recent advances in nano-sciences including colloids, interfaces as well as material science in general, are increasingly driven by artificial intelligence (AI), which combines theory, computation, experiment, data acquisition and analysis, and implementation. Previously, we covered applications of machine learning (ML) in nanoarchitectonics, where phenomena at nanoscale were compared with those at larger scale and where fundamental models were analyzed in application to colloids-, interface-, and material science area in general. Scrutinizing historical discovery paradigms from empirical observation to theoretical modeling, here in Part-II (as continuation of Adv. Colloids Interface Sci. 2025, 343, 103546), we extend that parallel to modern analysis workflows, data processing, evaluation metrics, application of language-based models. This review is organized around three pillars: (a) data acquisition, integration, and preprocessing for model-ready datasets; (b) model development encompassing classical (shallow) and advanced (deep) learning architectures; and (c) AI-assisted fabrication, characterization, and analysis of materials especially for colloidal and interfacial science. We compare major ML models - supervised, unsupervised, semi-supervised, and reinforcement learning - alongside advanced techniques such as transfer learning and autoencoders, highlighting applications across the materials innovation pipeline, from design and synthesis optimization to property prediction and performance evaluation. The concept of explainable Artificial Intelligence (XAI) is examined using the ITAP framework (interpretability, time efficiency, accuracy, and parameter sensitivity) to improve model transparency, reliability, and interpretability. Finally, we discuss the emergence of autonomous laboratories and outline key challenges, future directions toward transparent, reproducible, and sustainable AI-driven nanoarchitectonics, where adaptation and application of language-based models is expected to play an important role.
纳米科学的最新进展,包括胶体、界面以及一般的材料科学,越来越多地受到人工智能(AI)的推动,它结合了理论、计算、实验、数据采集和分析以及实现。之前,我们介绍了机器学习(ML)在纳米建筑学中的应用,其中纳米尺度的现象与更大尺度的现象进行了比较,并分析了基本模型在胶体、界面和材料科学领域的应用。在本文的第二部分(作为《胶体界面科学》2025、343、103546的延续)中,我们将从经验观察到理论建模的历史发现范式进行了仔细研究,并将其扩展到现代分析工作流、数据处理、评估指标、基于语言的模型的应用。本综述围绕三个支柱进行:(a)模型就绪数据集的数据采集、集成和预处理;(b)模型开发,包括经典(浅)和高级(深)学习架构;(c)人工智能辅助材料的制造、表征和分析,特别是用于胶体和界面科学。我们比较了主要的机器学习模型——监督、无监督、半监督和强化学习——以及迁移学习和自动编码器等先进技术,重点介绍了从设计和合成优化到性能预测和性能评估的材料创新管道中的应用。使用ITAP框架(可解释性、时间效率、准确性和参数敏感性)来检查可解释人工智能(XAI)的概念,以提高模型透明度、可靠性和可解释性。最后,我们讨论了自主实验室的出现,概述了关键挑战,以及透明、可复制和可持续的人工智能驱动纳米结构的未来方向,其中基于语言的模型的适应和应用预计将发挥重要作用。

The search for plant-based raw materials has strengthened the requirement to expand the performance of plant proteins. Nature-inspired conjugation, through mimicking natural post-translational modifications (PTMs), suggests a promising route to generate bio-conjugates for innovative emulsification and encapsulation. Conjugation is still the utmost usual method aimed at the modification of food proteins that can be fabricated via simple, easy-scalable procedures. As owning health-promoting aspects, bio-conjugates can introduce the clean/green (label) ingredients, compared with inconvenient and costly techniques. This study is taking a cue from nature for alternating the plant-based proteins through polysaccharides, polyphenols and lipid components and designing green plant-based nano-conjugates (via the selection of proper compounds). Nevertheless, this review critically evaluates a central restriction as there is an important biomimetic gap between the accurate and effective alterations created in nature and the simple and non-detailed approaches such as Maillard reaction, alkali treatment, etc. that are presently performed in vitro. Here, different methods of conjugating plant proteins with conjugates are described. Furthermore, the digestive tract or food matrix can promote the release of bioactive components, so the characteristics of drug delivery systems that can influence such phenomena will be discussed, as well as the technical-functional applications of such systems and drug delivery systems. Also, health-related risk assessments related to natural reactions and bio-conjugated nanostructures will be discussed. Lastly, we provide a critical perspective on the tasks of scalability, regulatory, and safety verification. We provide a forward-looking review of how a more rational, nature-inspired design philosophy can push the boundaries and hasten the expansion of next-generation green/clean (label) colloidal delivery systems.
对植物性原料的寻找加强了扩大植物蛋白性能的要求。通过模仿自然的翻译后修饰(PTMs),自然启发偶联提出了一种有前途的途径来产生用于创新乳化和封装的生物偶联物。偶联仍然是最常用的方法,旨在修改食品蛋白质,可以通过简单,易于扩展的程序制造。生物偶联物由于具有促进健康的方面,可以引入清洁/绿色(标签)成分,而不方便和昂贵的技术。本研究从自然界获得线索,通过多糖、多酚和脂质成分交替使用植物蛋白,并设计绿色植物基纳米偶联物(通过选择适当的化合物)。然而,这篇综述批判性地评估了一个中心限制,因为在自然界中产生的准确和有效的改变与目前在体外进行的简单和不详细的方法(如美拉德反应、碱处理等)之间存在重要的仿生差距。本文介绍了植物蛋白与缀合物结合的不同方法。此外,消化道或食物基质可以促进生物活性成分的释放,因此将讨论影响这种现象的药物传递系统的特性,以及这些系统和药物传递系统的技术功能应用。此外,将讨论与自然反应和生物共轭纳米结构有关的健康相关风险评估。最后,我们提供了可扩展性、监管和安全验证任务的关键观点。我们提供了一个前瞻性的回顾,一个更理性的,自然启发的设计理念如何推动边界和加速下一代绿色/清洁(标签)胶体输送系统的扩展。

Emulsion, including oil-in-water (O/W) and water-in-oil (W/O) emulsions, has garnered significant attention for coal flotation separation due to its potential to enhancing dynamic processes. However, with the consumption of high-quality coal resources and the implementation of the worldwide carbon reduction strategy, large-scale separation of low-quality coal (low-rank/oxidized coal) resources have become an important choice to ensure energy supplement and green development of coal industry. This review introduces the background and importance of emulsion collector technology in low-rank/oxidized coal flotation and analyzes its fundamental principles, including collector-particle-bubble interactions involving multi-scale interfacial mechanics. Then, the review discusses research progress in various emulsion collectors, such as traditional coarse emulsion, microemulsion, nanoemulsion, high-internal phase emulsion and Pickering emulsion, from high/low energy emulsification selection, emulsion formulation optimization and oil-water interfacial behavior aspects. Specifically, the emulsion collectors can effectively enhance the dispersibility of traditional oily collectors and decrease their dosages, as well as improve the attachment efficiency and hydrophobicity of coal surface, thereby enhancing the flotation separation effects. The complicated physicochemical enhancing mechanisms between emulsion collectors, coal particles and flotation bubbles are systematically described and warrant further in-depth investigation. This review concludes with a summary of the prospects of emulsion technology in improving low-rank coal flotation efficiency, reducing agent consumption and mitigating environmental impacts. It proposes future research directions, including enhanced emulsion structure-activity relationship analysis, targeted emulsifiers design, flotation dynamic process optimization, and large-scale application, to promote commercialization and sustainable development.
乳状液包括油包水(O/W)和油包水(W/O)乳状液,由于其具有增强动态过程的潜力,在煤浮选分离中受到了广泛的关注。然而,随着优质煤炭资源的消耗和世界范围内碳减排战略的实施,低品质煤(低阶/氧化煤)资源的大规模分离已成为保证煤炭工业能源补充和绿色发展的重要选择。本文介绍了乳化液捕收剂技术在低氧化煤浮选中的应用背景和重要性,分析了其基本原理,包括捕收剂-颗粒-气泡的多尺度界面力学相互作用。然后,从高低能乳化选择、乳液配方优化和油水界面行为等方面,综述了传统粗乳液、微乳液、纳米乳液、高内相乳液和皮克林乳液等乳液捕收剂的研究进展。其中,乳化液捕收剂能有效提高传统油性捕收剂的分散性,减少其用量,提高煤表面的附着效率和疏水性,从而提高浮选分离效果。系统描述了乳化液捕收剂、煤颗粒和浮选气泡之间复杂的物理化学增强机理,值得进一步深入研究。最后,对乳化液技术在提高低阶煤浮选效率、降低药剂用量、减轻环境影响等方面的应用前景进行了展望。提出了加强乳化液构效关系分析、针对性乳化剂设计、浮选动态流程优化、规模化应用等未来研究方向,以促进商业化和可持续发展。
