Pharmacotherapy is the core approach for treating various brain diseases. However, the intricate anatomical structure and the blood–brain barrier (BBB) of the brain present challenges for intracerebral drug delivery and therapeutic efficacy. Although systemic administration and surgical interventions can alleviate symptoms, they are limited by low therapeutic effects and potential adverse side effects. Moreover, due to their complex pathogenesis, insidious development, and deep-seated lesions, brain diseases are difficult to diagnose accurately. To address these challenges, there is an urgent need to develop intelligent nanocarriers that can efficiently load drugs and penetrate the BBB for precise therapy of brain diseases. In this connection, micro/nanorobots (MNRs) are multifunctional drug carriers at the micro-nano scale, which possess exceptional penetration and targeting capabilities. Employing externally powered propulsion or chemical self-propulsion, MNRs can navigate in the brain and cross the BBB. This review comprehensively summarizes the recent advances and future outlook of smart MNR drug delivery systems for brain disease treatment. It covers broad topics from nanocarriers to active smart MNRs. Furthermore, it elucidates the therapeutic mechanisms of these smart MNR drug delivery systems in brain diseases based on pathogenesis and pathology. Our aim is to provide a reference for designing and developing novel smart MNRs for drug delivery in the brain, paving the way for their clinical applications in treating brain diseases.

Over the past few decades, various antifogging strategies and preparation methods have been proposed. Unfortunately, a surface with a single antifogging function cannot achieve a wide range of practical applications. For example, medical endoscopes require antifogging and antibacterial capabilities to improve diagnostic accuracy and safety. Inspired by the near-perfect multifunctional properties of natural creatures, antifogging materials with specific functions have drawn more and more attention owing to their promising and wide applications. However, the design of bioinspired antifogging surfaces with broad applicability still presents some challenges, such as the integration of multifunctional properties, and the optimization of preparation routes. In this review, beginning with the fogging mechanism and wettability theory, the latest antifogging surface materials and pattern designs are analyzed in detail and critically evaluated. The natural biomaterials with multifunctional characteristics are summarized, and the integration mechanism and design difficulties of the four multifunctional characteristics are then emphatically analyzed. Based on artificial intelligence (AI) assisted design optimization, we introduce the neural network into the bionic multifunction antifogging path realization for the first time and summarize the antifogging prototype and antifogging multifunction database. Finally, the challenges and future trends of bioinspired multifunction antifogging surfaces (MF-AFS) are presented.

Lignocellulose offers significant promise as a renewable and environmentally sustainable material for construction, while its inherent combustibility poses a major challenge to its widespread application, especially in fire-sensitive environments. In this review, the combustion behavior of lignocellulose and the key mechanisms underlying its flame-retardant strategies are examined. Various classes of flame retardants (FRs), categorized based on the functional elements, are discussed in terms of their flame-retardant mechanisms and interactions with lignocellulosic substrates. Emerging approaches that integrate FRs are explored and compared, with a focus on enhancing flame resistance while minimizing their adverse effects on material properties. Finally, the review concludes with an outlook on current challenges and future research directions, shedding the light to develop more effective, durable, and sustainable flame-retardant solutions for lignocellulose-based materials.

Triptycene, a member of a distinct class of aromatic compounds called iptycenes, has garnered significant attention across various research domains. In recent years, triptycene and its derivatives have emerged as valuable and efficient building blocks for the design and synthesis of novel porous materials with tailored structures and properties. Porous organic polymers (POPs) based on triptycene are organic macromolecules regarded as emerging materials because of their high carbon content, high specific surface area, tunable porosity, low density, high chemical and thermal stability and variable composition. Triptycene-based POPs have demonstrated their competitiveness in various applications, including but not limited to gas storage and separation, water treatment, and catalysis applications. This review comprehensively summarizes recent research on triptycene-based porous organic polymers in materials chemistry.

Bioprinting that can quickly generate custom-shaped organ-like constructs opens up a new horizon for tissue engineering and regenerative medicine. The importance of bioinks cannot be overemphasized in advancing bioprinting development. Superior to conventional static bioink, dynamic bioink, mimicking the natural extracellular matrix, possesses reversible dynamic molecular networks that provide cellular activity and growth and thus enhance the maturation of bioprinted organ-like constructs, which has gained lots of attention and developed rapidly in the past decade. This paper completely summarizes the progress of dynamic bioink in bioprinting. First, we outline the molecular design principle of dynamic bioinks, involving two main patterns: supramolecular force and reversible chemical bonding. Then, key factors of dynamic bioinks in advancing bioprinting, including printability, structural stability, and modulation of cell behavior, are highlighted. Finally, the review further discusses the challenges and perspectives in fabricating tissues and organs with dynamic bioinks, aiming to offer an illuminating insight into bioprinting.

Single-atom catalysts have recently emerged as a revolutionary frontier in catalysis, energy production, and storage. Due to their compositional diversity, structural tunability, and modulated distinctive electronic properties, SACs pave significant promises for viable avenues toward a more sustainable future. Here, the discussion begins with the emergence of SACs, their synthesis techniques to regulate atomic dispersion, atomically-resolved advanced characterizations, probing different supports, and engineering strategies to boost stability and reactivity. This review as a key reference in this field comprises the mechanistic understanding of SACs in electrocatalysis, photocatalysis, and thermocatalysis for energy and environmental applications. We also discussed their transformative potential in H2 and O2 evolution reactions for water splitting, the reduction of O2, carbon dioxide, N2, and nitrate for electrocatalysis and photocatalysis, and their remarkable role in energy storage technologies, including metal-O2, lithium-sulfur, and metal-CO2 batteries. Additionally, we assess their efficiency in environmental remediation by removing harmful nitrogen oxides, various hydrogenation processes, catalytic oxidation, and CO2 hydrogenation, which sets this review apart from others. Despite the considerable progress, challenges persist in the scalability and commercial implementation of SACs. This comprehensive review significantly delivers valuable insights into the current advancement of SACs, highlighting their substantial potential and suggesting future research avenues that would enable next-generation technologies for energy conversion, storage, environmental sustainability, and various other functional applications.

Metal-organic frameworks (MOFs) represent a category of intricate coordination polymers that are formed by the deliberate assembly of metal ions/clusters with organic ligands via coordination bonds. Their hybrid inorganic–organic composition and programmable structural adaptability endow them with multifunctionality. This integration enables degradation-controlled release of bioactive components, positioning MOFs as a uniquely versatile platform for biomedical applications. This review systematically outlines the structural taxonomy of MOFs and underscores their transformative potential in pharmaceutical delivery, therapeutic interventions, and biomedical imaging applications. The degradation behavior of MOFs is systematically summarized, as it governs the controlled release of guest molecules and metal ions, critically influencing their biosafety and therapeutic efficacy. Therefore, we further summarize the impacts of MOF degradation products in both in vitro and in vivo environments. Finally, we outline the challenges in translating laboratory findings into clinical products, and propose future research directions, so that to guide the rational design and construction of MOF-based biomedical platforms.

Polymer composites embedded with functional particles (e.g., conductive, thermally conductive, or magnetic fillers) integrate the processability of polymers with the tailored functionalities of these additives. However, conventional composites often necessitate excessively high loadings to establish percolation networks, leading to challenges such as increased costs, diminished mechanical performance, and compromised processability. Segregated structures-where particles are selectively localized at polymer domain interfaces-significantly enhance filler utilization efficiency, outperforming traditional composites with uniformly dispersed particles. Since our group’s seminal 2014 review on electrically conductive segregated polymer composites, extensive advancements have been achieved across diverse applications, including electromagnetic interference shielding, thermal management, and gas barriers. Innovative processing strategies have also been tailored to accommodate various polymer matrices. Despite these breakthroughs, critical gaps persist in understanding the mechanistic interplay and scalable fabrication of multifunctional segregated systems. This review systematically synthesizes the progress in segregated polymer composites over the past decade, emphasizing novel fabrication techniques, matrix-dependent design principles, and emerging functional applications. We critically analyze persistent challenges-such as interfacial control, and scalability-alongside recent solutions and evolving research trends. By elucidating structure–property correlations and offering actionable design guidelines, this work aims to drive the broader adoption of segregated structures and accelerate the development of next-generation high-performance functional materials.

However, conventional composites often necessitate excessively high loadings to establish percolation networks, leading to challenges such as increased costs, diminished mechanical performance, and compromised processability. Segregated structures-where particles are selectively localized at polymer domain interfaces-significantly enhance filler utilization efficiency, outperforming traditional composites with uniformly dispersed particles. Since our group’s seminal 2014 review on electrically conductive segregated polymer composites, extensive advancements have been achieved across diverse applications, including electromagnetic interference shielding, thermal management, and gas barriers. Innovative processing strategies have also been tailored to accommodate various polymer matrices. Despite these breakthroughs, critical gaps persist in understanding the mechanistic interplay and scalable fabrication of multifunctional segregated systems. This review systematically synthesizes the progress in segregated polymer composites over the past decade, emphasizing novel fabrication techniques, matrix-dependent design principles, and emerging functional applications.
