In recent years, the one-pot transfer hydrogenation of furfural to γ-valerolactone (GVL) with biomass-derived alcohols as solvents and hydrogen donors has received extensive attention. Within this cascade pathway, furfuryl alcohol (FA) and alkyl levulinates (ALs) not only serve as key intermediates but can also be selectively produced as target products through rational tuning of catalyst active sites. Biomass-derived FA, ALs, and GVL have emerged as highly valuable platform molecules for the production of sustainable fuels and value-added chemicals. This review offers a comprehensive summary of recent progress in the one-pot transfer hydrogenation of furfural to GVL, with an integrated discussion of the related sub-reactions (furfural-to-FA, FA-to-ALs, furfural-to-ALs, and levulinic acid/ALs-to-GVL). Particular emphasis is placed on reaction mechanisms, the rational design of efficient catalysts for different reactions, and the roles of alcohol type and catalyst acidity/basicity in governing product distribution. Finally, feasible suggestions are proposed for enhancing catalytic performance and advancing practical applications.

MXenes, as a prominent class of two-dimensional (2D) transition metal carbides/nitrides, have attracted extensive attention in innovative biomedical applications due to their distinct layered structure, tunable electronic properties, good biocompatibility, and highly tunable surface/interlayer properties. Their biomedical functionalities largely rely on specific responses to external stimuli, e.g., light, mechanical force, ultrasound waves, magnetism, and heat, which are intrinsically linked to their precise structural design. However, the transition from empirical exploration to rational design of MXene-based nanomedicines is hindered by an insufficient understanding of the relationship between precise structural regulation, stimuli-responsive behavior, and biomedical efficacy. Existing reviews primarily focus on cataloging application scenarios rather than on an in-depth analysis of this core structure-functional relationship. To bridge this critical knowledge gap, this review focuses on the precise control of externally stimuli-responsive MXenes for biomedical applications. It systematically summarizes multi-dimensional structural regulation strategies, including atomic structure modulation, surface chemistry, interlayer engineering, and defect control, and dissects their regulatory effects on stimuli-responsive mechanisms. By integrating representative biomedical applications, a comprehensive structure-response-efficacy framework is established, providing critical theoretical support for the interdisciplinary innovation of materials science and biomedicine. Finally, we propose some challenges and future perspectives relevant to the continuous development of MXenes in biomedicine applications. This review addresses the current research gap and offers practical guidelines for designing smart MXene-based materials, which may promote the transformative potential of structurally engineered MXenes in advancing precision nanomedicine.

Carbanions were widely regarded as unstable and highly reactive species. However, in fact, the first example of stable and isolable carbanion-containing salts was reported more than 120 years ago. Recent research of stable carbanions endowed a renewed context such as carbanionic “substituents” for tuning the physicochemical properties of organic materials. In addition, unique electronic and geometric structures of the anionic carbon atom enable to be used as ionic liquids, polymer materials, and electrolytes. This review summarises notable recent advances in stable carbanions, covering their synthetic methodologies, chemical bonding behaviour, coordination chemistry, and emerging applications. In particular, carbanions stabilised by cyano, fluorinated sulfonyl, and phosphonio groups are discussed.

Photothermal therapy (PTT) has emerged as a pivotal strategy for cancer treatment due to its noninvasiveness, high spatiotemporal selectivity, and repeatable therapeutic potential. However, the clinical application of PTT is constrained by the low tissue penetration depth of light, suboptimal targeting efficiency of photothermal agents, and thermoresistance of tumor cells. To overcome these limitations, researchers have recently focused on the development of synergistic PTT-assisted combination strategies. These approaches leverage photothermal effect-mediated localized heat to enhance drug delivery efficiency, modulate the tumor microenvironment (e.g., alleviating hypoxia and promoting reactive oxygen species (ROS) generation), and activate antitumor immune responses, thereby achieving multimodal synergistic effects. This review systematically summarizes the recent advances in the integration of PTT with chemotherapy, radiotherapy, photodynamic therapy, sonodynamic therapy, chemodynamic therapy, thermodynamic therapy, gas therapy, ion therapy, immunotherapy, and gene therapy. Special emphasis is placed on the innovative enhancement mechanisms, including enhanced drug penetration, ROS amplification, and tumor microenvironment modulation. Furthermore, this review critically examines the current technical bottlenecks (e.g., precise treatment of deep-seated tumors and spatiotemporally controlled drug release) and outlines the future research directions. The insights provided herein establish a theoretical foundation and technical reference for developing novel photothermal effect-based combinatorial anticancer strategies.

Metal nanoclusters (MNCs) with atomically precise structures, tunable fluorescence, and unique catalytic activities have attracted significant attention in the development and construction of biosensing platforms. However, their practical applications still suffer from some limits to a certain extent, such as instability, easy aggregation, and sensitivity to environmental interference. The emergence of reticular framework materials (RFMs), including metal organic frameworks (MOFs), covalent organic frameworks (COFs), and hydrogen bonded organic frameworks (HOFs), provides an effective platform to overcome these limitations. The integration of MNCs with RFMs not only prevents aggregation and enhances structural stability through spatial confinement but also enables synergistic modulation of electronic structures and interfacial charge transfer, leading to remarkable improvements in optical, catalytic, and electrochemical properties. Recently, plenty of MNCs@RFMs have been successfully developed and have obtained widespread applications in the field of biosensing. In this review, we systematically summarized the latest progresses in synthesis and properties of MNCs@RFMs and their promising applications in construction of biosensors. First of all, the synthesis strategies and properties of MNCs@RFMs were comprehensively summarized and discussed. Then, research hotspots in this emerging field (i.e., structure-property relationships, performance improvement, and exploration on new performances of MNCs@RFMs) were discussed. In addition, promising applications of MNCs@RFMs in the fields of biosensing (i.e., fluorescence, electrochemical, electrochemiluminescence, colorimetric, and surface-enhanced Raman scattering) and portable detection devices were also summarized and discussed. Finally, current challenges and future research perspectives in this emerging field were outlined.

With the increasing demand for high-throughput biomolecular analysis, multiplexing technologies have emerged as powerful and efficient tools for large-scale biological investigations. Among various strategies, fluorescence-encoded barcodes have garnered particular attention owing to their high sensitivity, excellent biocompatibility, and potential for parallel analysis. This review provides a systematic and comprehensive overview of fluorescence-encoded barcodes, focusing on their design principles, encoding and decoding strategies, and applications. We first summarize the diverse fluorescent encoders and host materials that form the foundation of fluorescent barcoding systems, highlighting their respective merits and limitations in achieving multiplexed analysis. Next, we discuss the encoding dimensions of fluorescent barcodes—including fluorescence spectrum, lifetime, spatial pattern, and polarization—emphasizing that these parameters can be utilized independently or in combination to substantially enhance encoding capacity and analytical throughput. In addition, we examine recent progress in multimodal encoding strategies that integrate fluorescence encoding with other encoding modalities to further expand the multiplexing potential. The review then explores the decoding and applications of multidimensional fluorescence-encoded barcodes in multiplexed detection and imaging, with an emphasis on their performance in complex biological systems. Finally, we present a critical perspective on current challenges and future opportunities, aiming to inspire the development of next-generation fluorescent barcoding technologies for high-throughput biological analysis and precision diagnostics. We anticipate that this comprehensive summary will serve as a valuable reference for researchers seeking to advance the field of multiplexed detection and imaging.

The excessive use of fossil fuels has led to a sharp increase in atmospheric CO2 concentration, intensifying the greenhouse effect and posing serious challenges to environmental protection and energy sustainability. Solar-driven photocatalytic CO2 reduction has emerged as a green and feasible approach to convert CO2 into high-value-added fuels, thereby alleviating both environmental and energy pressures. Among various photocatalysts, carbon nitride (C3N4) has attracted extensive attention due to its visible-light responsiveness, excellent stability, and low cost. However, its catalytic efficiency is still limited by rapid charge recombination, low carrier mobility, and a small number of active sites. To address these limitations, various modification strategies have been proposed, including morphology control, element doping, heterojunction construction, vacancy engineering, and cocatalyst loading, aiming to enhance light absorption, charge separation, and catalytic activity. This review provides an in-depth overview of recent developments in C3N4 photocatalysts for CO2 reduction and their prospects, discusses the relationship between structure and performance, and briefly outlines the reaction conditions affecting photocatalytic activity. Finally, the challenges and prospects for the practical application of C3N4 are presented, providing valuable guidance for the rational design of efficient and sustainable photocatalytic systems.

The development of highly efficient electrocatalysts tailored for exchange membrane water electrolysis is pivotal for advancing large-scale green hydrogen production. Rare-earth (RE) elements exhibit unique advantages in modulating electronic structure and enhancing intrinsic electrocatalytic performance, owing to their distinctive 4f electron configuration and strong oxygen affinity. Understanding the precise roles of RE elements and their structure-activity relationships under operating conditions is essential for realizing their application potential. Herein, this review systematically elucidates the theoretical foundations of RE-based materials for boosting catalytic activity and stability from electronic properties. Then, we comprehensively summarize recent advances in RE-modified catalysts for OER and HER reactions and provide an overview of their emerging applications and feasibility in proton exchange membrane water electrolysis (PEMWE) and anion exchange membrane water electrolysis (AEMWE). Finally, we propose rational design strategies and future research directions to address current industrialization challenges. This review aims to provide the important guidance for developing next-generation RE-based electrocatalysts tailored for large-scale water electrolysis.

Metal–organic phosphorescence materials (MOPMs) are a type of highly efficient room-temperature phosphorescence (RTP) system characterized by the structural integration and photophysical coupling of metal-containing units and organic components. By combining the distinct advantages of both inorganic and pure organic RTP materials, MOPMs exhibit long lifetimes, robust photostability, and low toxicity. These attributes render them highly versatile across various fields. This review provides a comprehensive overview of MOPMs. It begins with their definition and classification, including metal-organic complexes, metal-organic polymers, metal-organic frameworks, metal nanoclusters, metal-doped carbon dots, metal-organic hybrid perovskites, and organic-inorganic metal halides. Subsequently, we systematically elucidate the luminescence mechanisms and the corresponding optical regulation strategies inherent to these systems. Finally, we discuss the applications of MOPMs in photoelectric devices, information storage, bioimaging, therapy, and sensing technologies. This review aims to inspire innovative designs of MOPMs and accelerate their future development for a broader spectrum of applications.
