Graphene and related materials are emerging revolutionary materials due to fascinating stimuli-responsive physiochemical properties having widespread applications in developing advanced nano-systems for detection, diagnostics, and therapeutics in biomedical fields. Various materials like metal nanoparticles, polymers, dyes, drugs, and proteins could be combined yielding graphene-based composite materials (GBCMs) to synergistically fulfill different biomedical requirements. The 2D conjugated structure, easy surface functionalization via covalent or van der Waal interactions, and combination with different components for versatile functionalities altogether contribute to the development of GBCM for healthcare applications. This review specifically focuses on GBCMs and discusses specific material properties relevant to their material applications in healthcare. Furthermore, the synthesis, toxicity, and biocompatibility of these GBCMs, and their interactions with biological materials are thoroughly discussed. Importantly, the recent cutting-edge applications in the field of healthcare, including its role in the development of antibacterial, anti-viral, and photothermal therapies, wound healing, drug delivery, neurodegenerative disease therapy, and biosensing based on GBCMs are well-updated. Additionally, the applications of GBCMs in point-of-care devices, wearable electronics, and tissue engineering are well summarized. We hope this review opens up more possibilities to design more innovative healthcare materials derived from graphene. © 2025 The Authors

Bio-based aerogels, which are poised as compelling thermal insulators, demand intricate synthesis procedures and have limited durability under harsh conditions. The integration of smart stimuli–response transitions in biomass aerogels holds promise as a solution, yet remains a challenge. Here, we introduce a pioneering strategy that employs reversible-gel-assisted ambient-pressure drying without organic solvents to craft multifunctional bio-based aerogels. By exploiting the thermally reversible gelling propensity of select biomasses, we anchor emulsified bubbles within cross-linked hydrogels, circumventing surface tension issues during mild drying. The resultant aerogels feature a robust porous matrix that is imbued with stable bubbles, yielding low thermal conductivity, high flame retardancy and robust resistance to diverse *** innovative approach facilitates a paradigm shift in intelligent fire protection in which aerogels transition from robust to flexible in response to water stimuli, effectively shielding against thermal hazards and external forces. This work opens up a facile, eco-friendly and mild way to fabricate advanced biomass aerogels with stimuli-responsive transformation.

A facile ligand engineering strategy to achieve ultra-highly efficient afterglow luminescence of ordinary metal salts

science China Chemistry 2025年

作者： Li Ya Liang Xiao Yuan Wang Ya Ting Gao Da Jun Wu Da Wei Li Bin Bin Chen School of Chemistry & Molecular Engineering East China University of Science and Technology Key Laboratory for Advanced Materials Shanghai Key Laboratory of Functional Materials Chemistry Feringa Nobel Prize Scientist Joint Research Center Frontiers Science Center for Materiobiology & Dynamic Chemistry East China University of Science and Technology

Ordinary metal salts have become a promising afterglow material because of the characteristics of wide sources, low cost, and easy availability. However, their extremely weak afterglow efficiency makes them rarely used in practical applications. In this study, we proposed a ligand engineering strategy to greatly enhance the afterglow efficiency of metal salts. Al2（SO4）3, as a typical metal salt, has only a photoluminescence quantum yield（PL QY） as low as 0.1% and an unmeasurable phosphorescent QY. After doping with dual organic ligands, the PL QY of Al2（SO4）3has increased by nearly 200 times, reaching 19.90%. Meanwhile, the afterglow intensity of Al2（SO4）3has increased by approximately 20 times, accompanied by a great increase in phosphorescent lifetime from 416.15 to 2870.08 ms（a about 7-time increase）. The enhancement mechanism of afterglow efficiency is ascribed to the fact that the excited electrons from the dual ligands can be directly captured by oxygen defects（trap）, then transferred to the emitters(Al3+ions), and ultimately achieving efficient afterglow luminescence. This study utilizes ligand engineering strategy to improve the afterglow luminescence efficiency of metal salts, achieving their applications in deep ultraviolet（UV）-excited light emitting devices and visual ethylene glycol recognition.
