Colloidal photonic crystals have drawn wide attention in a number of realms due to their manyapplications. Photonic microobjects can be processed by a combination of droplet-based microfluidics and the subsequent different post-processing approaches in a precisely controlled manner in terms of compositions, geometries, and functionalities, offering a wide range of properties for the resulting products. In this review, we provide a summary of colloidal-based photonic microobjects that have evolved from droplets produced by microfluidic devices with different configurations and designs. The colloidal building blocks can be either inert or responsive to external stimuli, which impart the colloidal photonic microobjects with tunable properties. By leveraging a number of post-processing strategies, including evaporation of solvents from the droplet templates, external field-guided assembly, selective sputter coating, controlled etching, osmosis regulating, etc., the obtained photonic microobjects eventually possessed diverse microstructures with different fashions, featuring the photonic microobjects with demanded photonic performances in sub-microscale or can be further organized for bulk applications. Finally, we analyze the challenges and present outlooks on future development trends regarding the construction of colloid-based photonic microobjects, including current issues, critical needs, and promising emerging photonic applications. Also, we propose some emerging scientific questions and engineering limitations may be worthy of exploration based on the combination of microfluidics processing, colloidal assembly, and post-treatments.

胶体光子晶体由于其广泛的应用，在许多领域引起了广泛的关注。光子微物体可以通过基于微滴的微流体和随后的不同后处理方法的组合以精确控制的方式在成分，几何形状和功能方面进行处理，为最终产品提供广泛的特性。本文综述了基于胶体的光子微物体的研究进展，这些微物体是由不同结构和设计的微流体装置产生的液滴演变而来的。胶体构建块可以是惰性的，也可以是响应外部刺激的，这使得胶体光子微物体具有可调谐的特性。通过利用液滴模板溶剂蒸发、外场引导组装、选择性溅射涂层、受控蚀刻、渗透调节等后处理策略，最终获得的光子微物体具有不同的微结构和不同的模式，具有亚微尺度下所需的光子性能或可进一步组织用于批量应用的光子微物体。最后，我们分析了胶体基光子微物体构建面临的挑战，并对未来的发展趋势进行了展望，包括当前的问题、关键需求和有前景的新兴光子应用。此外，我们还提出了一些新兴的科学问题和工程限制，这些问题和限制可能值得基于微流体处理、胶体组装和后处理的结合进行探索。

As the demand for functional foods and precision nutrition continues to rise, there is an urgent need for advanced delivery systems that improve the stability, bioavailability, and targeted release of sensitive bioactive compounds. Lactic acid bacteria (LAB), commonly found in fermented foods, have taken on a dual role—as both passive encapsulation targets and active delivery carriers—forming a conceptual basis for the development of next-generation food delivery systems. This review examines the interactions between LAB and various food-grade encapsulation materials including proteins (such as whey protein, casein, zein), polysaccharides (like alginate, chitosan), and lipids (such as liposomes, W/O/W emulsions), highlighting roles of electrostatic interactions, hydrogen bonding, hydrophobic interaction, covalent cross-linking, and interfacial self-assembly. Moreover, four emerging LAB-based delivery systems are classified: (i) surface adsorption via non-covalent interactions, (ii) intracellular loading driven by membrane transport or biosynthesis, (iii) co-encapsulation in hydrogels and emulsions, as well as (iv) engineered LAB capable of in situ synthesis and targeted release. The review also summarizes practical applications in hydrocolloid-rich food systems, such as yogurt, plant-based gels, and functional beverages. These applications highlight LAB's contribution to enhancing structural stability, controlled release, and nutritional functionality. Finally, key challenges are discussed, including the limited compatibility between encapsulating materials and food matrices, insufficient understanding of the interactions between exopolysaccharides and interfaces, and the need for in vivo validation. Based on these insights, future directions are proposed to guide the rational design of next-generation LAB-based delivery systems for precision nutrition and functional food innovation.

随着对功能性食品和精密营养的需求不断增加，迫切需要先进的递送系统来提高稳定性、生物利用度和敏感生物活性化合物的靶向释放。乳酸菌（LAB），常见于发酵食品中，作为被动封装目标和主动递送载体，具有双重作用，为下一代食品递送系统的发展奠定了概念基础。本文综述了乳清蛋白、酪蛋白、玉米蛋白等多种食品级包封材料与乳清蛋白、海藻酸盐、壳聚糖等多糖、脂质体等包封材料之间的相互作用，重点介绍了静电相互作用、氢键、疏水相互作用、共价交联和界面自组装等方面的作用。此外，四种新兴的基于实验室的递送系统被分类：(i)通过非共价相互作用的表面吸附，（ii）由膜运输或生物合成驱动的细胞内负载，（iii）在水凝胶和乳液中的共包封，以及（iv）能够原位合成和靶向释放的工程LAB。综述还总结了在富含水胶体的食品系统中的实际应用，如酸奶、植物性凝胶和功能饮料。这些应用突出了LAB在增强结构稳定性、控释和营养功能方面的贡献。最后，讨论了主要挑战，包括封装材料与食物基质之间的有限兼容性，对外多糖与界面之间相互作用的了解不足，以及体内验证的必要性。基于这些见解，提出了指导下一代基于实验室的精准营养和功能食品创新输送系统的合理设计的未来方向。

Breast cancer has become the most common type of cancer worldwide. Chemotherapy is a prevalent and efficacious treatment for breast cancer; yet, it presents several problems that might impact both the treatment's effectiveness and the patient's quality of life. Certain breast cancer cells exhibit inherent resistance to chemotherapeutic agents from the outset. Cancer cells may evolve throughout therapy, developing resistance to previously successful medications. This encompasses augmented drug efflux (e.g., via P-glycoprotein), enhanced DNA repair mechanisms, and modifications in drug targets. Moreover, conventional chemotherapy is impeded by several limitations, including poor drug solubility, reduced blood circulation time, harm to healthy tissues, drug resistance, and tumor recurrence. Consequently, it is essential to provide significant doses of chemotherapeutics to guarantee that a sufficient amount reaches the tumor and has the desired effect. Unfortunately, the administration of excessive pharmacological doses damages healthy tissue, resulting in various side effects including nausea, baldness, fatigue, immune system breakdown, sterility, and organ dysfunction. In this context, polymeric nanoparticles, including liposomes, nanocomposites, polymeric micelles, and dendrimers, have several benefits relative to conventional therapy. This encompasses greater circulation duration, superior targeting characteristics, compatibility with biological systems, natural degradability, and higher retention of drug-loaded nanoparticles inside tumors, leading to diminished side effects in other bodily regions. This work offers innovative perspectives on the use of polymeric nanoparticles as an advanced nano-drug delivery technology for chemotherapeutics, particularly in breast cancer therapy. It also analyses several kinds of copolymers used in the synthesis of polymeric micelles. This study examines the physicochemical features of these nanoparticles, their synthesis methods, characterization techniques, pharmacokinetic behavior, and their applicability in breast cancer diagnostics.

乳腺癌已经成为世界上最常见的癌症类型。化疗是一种普遍有效的治疗乳腺癌的方法；然而，它提出了几个问题，可能会影响治疗的有效性和患者的生活质量。某些乳腺癌细胞从一开始就表现出对化疗药物的固有耐药性。癌细胞可能在整个治疗过程中进化，对以前成功的药物产生耐药性。这包括增强的药物外排（例如，通过p -糖蛋白），增强的DNA修复机制和药物靶点的修饰。此外，常规化疗存在药物溶解度差、血液循环时间缩短、损害健康组织、耐药、肿瘤复发等局限性。因此，必须提供显著剂量的化疗药物，以保证足够的剂量到达肿瘤并具有预期的效果。不幸的是，过量的药物剂量会损害健康组织，导致各种副作用，包括恶心、秃顶、疲劳、免疫系统崩溃、不育和器官功能障碍。在这种情况下，聚合物纳米颗粒，包括脂质体、纳米复合材料、聚合物胶束和树状大分子，相对于传统治疗有几个好处。这包括更长的循环时间，优越的靶向特性，与生物系统的相容性，自然降解性，以及肿瘤内载药纳米颗粒的更高保留率，从而减少了其他身体部位的副作用。这项工作为聚合物纳米颗粒作为一种先进的纳米药物递送技术用于化疗，特别是乳腺癌治疗提供了创新的视角。还分析了几种用于合成聚合物胶束的共聚物。本研究探讨了这些纳米颗粒的物理化学特征、它们的合成方法、表征技术、药代动力学行为以及它们在乳腺癌诊断中的适用性。

The integration of flexible sensors is crucial for soft robots to perform specific tasks during complex deformation (such as bending, torsion, compression, stretching, etc.) and interactions with unstructured environments. However, it is still a significant challenge to construct high-performance flexible sensors due to the high flexibility, deformation ability, and multiple degrees of freedom of soft robots. An efficient approach is to convert the continuous deformations of soft robots into discrete representations, which enable the scientists to better understand the deformation process and clarify the impact of surface and interface on sensor performance. Thus, intelligent algorithms can be used to further optimize the number and arrangement of sensors, improving the overall efficiency and performance of the system. This paper focuses on the impact of surface interface construction on the performance of flexible sensors. First of all, based on the basic classification of flexible sensors, this paper systematically analyzes the construction strategy of the surface and interface of flexible sensors, including surface structure optimization, microstructure array design and void structure. Secondly, the preparation methods of different surface and interfaces are discussed in detail. Then, the wide application of flexible sensors in multiple fields is discussed. Finally, the future development direction of flexible sensors is summarized and prospected.

柔性传感器的集成对于软机器人在复杂变形（如弯曲、扭转、压缩、拉伸等）和与非结构化环境的交互过程中执行特定任务至关重要。然而，由于柔性机器人的高柔性、高变形能力和多自由度，构建高性能柔性传感器仍然是一个重大挑战。一种有效的方法是将软体机器人的连续变形转化为离散表示，这使科学家能够更好地理解变形过程，并阐明表面和界面对传感器性能的影响。因此，可以使用智能算法进一步优化传感器的数量和排列，提高系统的整体效率和性能。本文主要研究了表面界面结构对柔性传感器性能的影响。首先，在对柔性传感器进行基本分类的基础上，系统分析了柔性传感器表面和界面的构造策略，包括表面结构优化、微结构阵列设计和空隙结构。其次，详细讨论了不同表面和界面的制备方法。然后，讨论了柔性传感器在多个领域的广泛应用。最后，对柔性传感器的未来发展方向进行了总结和展望。

Over the last two decades, the healthcare field has witnessed exponential growth in the applications of stimuli-responsive biomaterials for diverse therapeutic purposes. This has led to the development of numerous smart dental biomaterials tailored for the precise and on-demand delivery of therapeutic agents. By leveraging the specific exogenous and endogenous stimuli, these smart materials fine-tune their physicochemical properties to improve the clinical efficacy of the therapeutic agents and mitigate their side effects. This review systemically examines the design and objectives of the smart biomaterials platforms specifically for dental and associated soft tissue. Additionally, we comprehensively summarize various smart biomaterials-based delivery platforms, categorized by the nature of the stimuli, including pH, enzyme, temperature, light, ultrasound, electricity, and pressure. Furthermore, this review discusses several newly developed smart platforms utilized in different dental conditions, with a particular focus on those undergoing clinical trials. This review aims to provide an overview of the state-of-the-art smart drug delivery systems in dentistry and offer insights into developing next-generation platforms to address various clinical needs, such as infection eradication, inflammation modulation, tissue regeneration, and immunotherapy.

Hydrogels have emerged as thriving materials for developing biomedical devices due to their biocompatibility and hydrophilic nature, encompassing various fields from biomedical engineering and pharmaceuticals to wound care and tissue scaffolding. Nevertheless, traditional hydrogels are beset with poor mechanical strength, limited controlled release of medicines, and irreversible chain breakage, all of which compromise their efficacy in practice. The desirable performance of hydrogels can be notably lifted upon incorporating nanomaterials, yielding tunable functions for devising next-generation biocompatible structures. Despite the alluring prospects offered by hydrogel nanocomposites, the processing of these materials is still in its infancy and remains full of challenges to produce personalized, tangible items. Herein, we endeavor to bridge the gap between hydrogel nanocomposites for biomedical applications with additive manufacturing processing, providing a useful guideline for comparing and selecting viable three-dimensional (3D) printing approaches. We review the background of synthesizing hydrogel nanocomposites along with the key concepts toward biomedical applications, featuring a survey on the recent reports on 3D printing of hydrogel nanocomposites for developing customized tissues, drug delivery, bioadhesives, wound dressing, and biosensors.

由于其生物相容性和亲水性，水凝胶已成为开发生物医学设备的蓬勃发展的材料，涵盖了从生物医学工程和制药到伤口护理和组织支架的各个领域。但传统水凝胶存在机械强度差、药物控释受限、不可逆断链等问题，影响了其在实际应用中的效果。在加入纳米材料后，水凝胶的理想性能可以显著提高，为设计下一代生物相容性结构提供可调功能。尽管水凝胶纳米复合材料提供了诱人的前景，但这些材料的加工仍处于起步阶段，要生产个性化的、有形的产品仍然充满挑战。在此，我们努力弥合水凝胶纳米复合材料在生物医学应用与增材制造工艺之间的差距，为比较和选择可行的三维（3D）打印方法提供有用的指导。我们回顾了水凝胶纳米复合材料的合成背景以及生物医学应用的关键概念，重点介绍了3D打印水凝胶纳米复合材料用于开发定制组织，药物输送，生物粘合剂，伤口敷料和生物传感器的最新报道。

The colloid-chemical properties of materials are a key factor that determines the course of their dewatering and influences the choice of treatment method, its efficiency, and duration.

Based on the analysis of publications, it has been shown that fine-dispersed clay systems are among the most challenging materials, as mechanical moisture removal is problematic due to their high hydrodynamic resistance, while thermal drying requires significant energy input. In this case, the method that optimally combines intensive dewatering with relatively low energy consumption is the application of an electric field enhanced by pressure.

The review discusses the fundamental principles of electroosmotic dewatering of such systems, the complications that arise during their treatment, and ways to eliminate them.

It is proven that the efficiency of dewatering is determined by the electrosurface characteristics of particles, which can be controlled by adjusting the pore solution pH. The presented experimental data demonstrate an increase in the degree of dewatering with the rise of the electrokinetic potential of particles, as well as the conditions under which its maximum is achieved.

It is shown that dewatering can be intensified by using additive porous particles, whose surface charge and electrical conductivity exceed those of the particles in the treated dispersion.

A positive effect is reached through optimization of the electric field distribution and the ratio of the electrokinetic characteristics of the particles, while maintaining the necessary system porosity. The maximum result is achieved when the surface and bulk properties of the base and additive dispersions exhibit a synergistic effect on dewatering.

材料的胶体化学性质是决定其脱水过程的关键因素，影响处理方法的选择、效率和持续时间。根据对出版物的分析，已经表明，细分散粘土系统是最具挑战性的材料之一，因为机械除湿是有问题的，因为它们的高水动力阻力，而热干燥需要大量的能量输入。在这种情况下，将密集脱水与相对低能耗相结合的最佳方法是施加压力增强的电场。本文讨论了电渗透脱水的基本原理、治疗过程中出现的并发症及消除方法。实验证明，脱水效率由颗粒的电表面特性决定，可以通过调节孔隙溶液ph来控制。实验数据表明，随着颗粒电动势的升高，脱水程度增加，脱水程度达到最大值的条件也随之增加。结果表明，添加多孔颗粒可以强化脱水，其表面电荷和电导率超过处理过的分散体中的颗粒。在保持必要的系统孔隙率的同时，通过优化电场分布和颗粒电动特性的比例，达到了积极的效果。当基料和添加剂分散体的表面和体积特性在脱水过程中表现出协同作用时，效果最好。

Evaporation of liquid droplets, especially water and aqueous solutions, is the basis of various industrial technologies and is found in many natural phenomena. In particular, the analysis of droplet evaporation is important to model the drying process of solutions in the pharmaceutical and food industries, the thermal processes in combustion engines, the use of water mist curtains in fire safety and the reasonable use of irrigation in agriculture. Climate studies, including the Earth's atmosphere and the ocean-atmosphere interactions, also require computational modeling evaporation of water droplets with various impurities and seawater droplets in the ocean's surface layer. The present review paper includes analyses of the evaporation of relatively large sessile droplets and small droplets suspended in ambient air. The paper describes some little-known details regarding modeling the radiative evaporation of single droplets and droplet layers including the spectral radiative transfer analysis. The review also covers the evaporation of sessile droplets, which is relevant in various applications. The impact of interfacial effects, such as contact angle hysteresis and Marangoni flows, on sessile droplet evaporation is discussed. Trends for future investigation are foreseen.

With the rapid development of global industrialization, heavy metals(HM) pollution in water bodies worldwide has become one of the key environmental challenges due to its persistent toxicity and bioaccumulation risks. Lead (Pb) and cadmium (Cd), as common and typical representatives of toxic heavy metals, are primarily originating from wastewater discharge from industries such as metallurgy, electroplating, and pesticides. Due to their heightened toxicity risks, membrane separation, precipitation, adsorption, and other technologies have been proposed. Among them, adsorption has been widely recognized due to its simple operation, low cost, and remarkable effectiveness. Adsorption materials are the technical core of adsorption methods. MOF materials are superior to traditional carbon based, silicon-based, natural materials and other adsorption materials due to their high selectivity and controllability. However, there is no systematic comparison of MOF materials for removing Pb and Cd from wastewater. The diversity, adsorption differences and applicable scenarios of these materials make their industrial application difficult. This article systematically summarizes the MOF materials and functionalization methods for removing Pb and Cd from wastewater, and compares their performance indicators such as maximum capacity, selectivity coefficients, and regeneration cycle times. The advantages and disadvantages of the materials are compared, and the applicable scenarios of different materials are clarified. To address the defects and drawbacks of MOF materials, an innovative approach has been proposed to enhancing the synthesis, functionalization, and material recycling of MOF materials through multiple physical fields. This approach precisely regulates the nucleation, pore structure, exposure of active sites, and controllability of functional group grafting in MOF materials. This collaborative strategy is not only expected to break through the limits of traditional material performance, but also to achieve intelligent adsorption systems that respond to extreme environmental stress. This study provides a forward-looking perspective for designing next-generation MOF materials to achieve sustainable water purification.

随着全球工业化的快速发展，世界范围内水体重金属污染因其持续的毒性和生物蓄积性风险已成为重大的环境挑战之一。铅（Pb）和镉（Cd）是有毒重金属的常见和典型代表，主要来源于冶金、电镀、农药等行业的废水排放。由于其较高的毒性风险，人们提出了膜分离、沉淀、吸附等技术。其中，吸附因其操作简单、成本低、效果显著而得到广泛认可。吸附材料是吸附方法的技术核心。MOF材料具有高选择性和可控性，优于传统的碳基、硅基、天然材料等吸附材料。然而，目前还没有系统比较MOF材料去除废水中铅和镉的效果。这些材料的多样性、吸附差异和适用场合给它们的工业应用带来了困难。本文系统总结了MOF材料和功能化方法对废水中铅、镉的去除效果，并对其最大容量、选择性系数、再生循环次数等性能指标进行了比较。比较了各种材料的优缺点，明确了不同材料的适用场景。针对MOF材料的缺陷和不足，提出了一种创新的方法，通过多个物理领域来增强MOF材料的合成、功能化和材料回收。这种方法精确地调控了MOF材料的成核、孔结构、活性位点的暴露和官能团接枝的可控性。这种协作策略不仅有望突破传统材料性能的限制，还有望实现应对极端环境压力的智能吸附系统。该研究为设计下一代MOF材料以实现可持续的水净化提供了前瞻性的视角。
