via physical， chemical， and biological strategies. This article elucidated the biosynthetic principles and preparation methods of BC， along with its fundamental functional characteristics such as biocompatibility， biodegradability， high mechanical strength， and high nano-porosity. Furthermore， it reviewed recent advances in BC-based composite materials endowed with biomedical functionalities， including hemostasis， antibacterial activity， and anti-inflammatory effects. Additionally， diverse application forms of BC-based composites in hemostatic materials and wound dressings， such as hydrogel dressings， wound repair patches， and sponge dressings， were discussed. Finally， the prospects for BC-based composite materials in the field of wound healing were outlined.]]> 2025/9/23 19:02:06 YANG Lanyan,SHI Liu,CHEN Seng,WANG Lan,WU Wenjin,CHEN Lang,XIONG Guangquan,PENG Yongbo,GUO Xiaojia 5true in-situ construction of a wood sponge （Cu-WS） featuring laccase-like Cu-Nₓ active sites. The stable coordination structure formed between the aminated cellulose， hemicellulose， lignin， and Cu²⁺ endowed Cu-WS with catalytic properties closely resembling natural laccase. Specifically， its Michaelis constant （Kₘ） for 2，4-dichlorophenol （2，4-DCP） was 0.27 mmol/L， comparable to that of natural laccase （K_m = 0.24 mmol/L）， and its maximum reaction velocity （v_max） was enhanced by 23 times. Remarkably， Cu-WS retained >50% catalytic relative activity after 210 d storage and >90% over 7 reuse cycles， outperforming natural laccase. For epinephrine detection， Cu-WS achieved high affinity （K_m = 4.07 × 10⁻⁶ mol/L） and catalytic efficiency （v_max = 1.04 × 10⁻⁶ mol/（L·s））， with a linear range of 5~30 μg/mL and LOD of 0.019 6 μg/mL. Leveraging the 3D porous wood framework for enhanced mass transfer and Cu-N_x-mediated biomimetic catalysis， Cu-WS enabled rapid， instrument-free colorimetric detection.]]> 2025/9/23 19:02:07 LI Lijun,DUAN Tong,DU Fan,CHEN Xuemei,YANG Guangzhao,ZHANG Xue,ZHANG Xueming 4true films， sprays， patches， microneedles， injectable hydrogels）.

The producing HACC/HDTMS-n-TiO₂ membrane-coated bamboo fibers were used to fabricate a high hydrophobic and antibacterial paper. The surface morphology， elemental composition， chemical structure， mechanical properties， and hydrophobic performance of the antibacterial paper were systematically characterized. The results demonstrated that when the number of HACC/HDTMS-n-TiO₂ membrane reached 8， the tensile index of the hydrophobic and antibacterial paper attained 45.0 N·m/g. Moreover， after immersion in acid or alkali solutions for 5 h， the water contact angle remained over 110°. The antibacterial tests revealed that the paper coated with 8 layers of HACC/HDTMS-n-TiO₂ achieved antibacterial rates exceeding 98% against both E.coli and S.aureus. These findings indicated that the high hydrophobic and antibacterial paper exhibited significant potential for application in food packaging.]]> 2025/9/23 19:02:08 LI Bin,HAN Jingfeng,TAO Shaoqu,ZHANG Zhen,XU Xinying,YAO Chunli 2true 2025/9/23 19:02:10 TANG Song,HU Jingfang,WANG Linzhe,WEI Wensong,SONG Yu,LI Yansheng,GAO Guowei 1true
