To address water pollution and limitations of existing photocatalysts, mannitol was used to fabricate tetragonal layered BiOX (X = Cl, Br, I) via a room-temperature precipitation method. Among them, BiOI with nanosheet structure exhibited broader light absorption, enhanced charge separation, and higher surface oxygen vacancies. These advantages enabled BiOI to degrade mixed pollutants (dyes, antibiotics, aromatic compounds) under visible light, achieving over 80% efficiency within 180 min. The main active species were h + and ·O 2 − . BiOI showed excellent recyclability and stability. This simple, eco-friendly synthesis offers great potential for treating complex industrial wastewater.

en This link goes to a English section zh This link goes to a Chinese section The healing of diabetic chronic wounds is hindered by multiple pathological barriers, including oxidative stress imbalance induced by hyperglycemia, persistent bacterial infection, and impaired neovascular function. This study developed an F127–HA–BiOCl@CeO 2 (FHBC) hydrogel dressing with acoustic responsiveness, achieving tissue repair through systematic intervention in the unstable wound microenvironment. The system utilizes the acoustic streaming effect induced by low-intensity ultrasound (US) to effectively overcome the barrier posed by viscous exudate in chronic wounds to the deep diffusion of active components. The core mechanism involves electron orbital hybridization between BiOCl and CeO 2 , facilitating interfacial charge transfer. This enables the loaded CeO 2 nanoenzymes to fully utilize their abundant oxygen vacancies and Ce 3+ /Ce 4+ redox pairs. This process achieves efficient capture and conversion of excess reactive oxygen species (ROS), significantly alleviating oxidative stress damage to endogenous cells. Concurrently, the system synergistically employs acoustic physical effects to suppress pathogen proliferation and disrupt biofilm physical structures. As the redox homeostasis of wound is restored, the dressing further mediates transformation of the local immune microenvironment. It induces pro-inflammatory macrophages to polarize toward a reparative state, thereby releasing inhibition on the vascular endothelial growth signaling pathway. In vitro and in vivo experiments confirm that this system achieves deep integration of antibacterial, antioxidant, and immunomodulatory functions through the synergistic effects of acoustically assisted permeation and electronic energy level catalytic equilibrium. This promotes functional vascular network reconstruction and skin tissue regeneration in diabetic wounds. 摘要 en This link goes to a English section zh This link goes to a Chinese section 糖尿病慢性创面的愈合受到多重病理屏障的阻碍,包括高糖诱导的氧化应激失衡、持续性细菌感染以及新生血管功能受损等。为此,本研究构建了一种具有超声响应特性的F127–HA–BiOCl@CeO 2 (FHBC)水凝胶敷料,通过对不稳定创面微环境进行系统性干预,实现组织修复。该体系利用低强度超声(US)诱导的声流效应,有效克服慢性创面黏稠渗出液对活性组分向深层组织扩散的阻碍。其核心机制在于BiOCl与CeO 2 之间的电子轨道杂化促进界面电荷转移,使负载的CeO 2 纳米酶能够充分发挥丰富氧空位以及Ce 3+ /Ce 4+ 氧化还原对的作用,从而高效捕获并转化过量活性氧(ROS),显著缓解内源性细胞所受的氧化应激损伤。同时,该系统协同利用超声的物理效应抑制病原菌增殖并破坏生物被膜结构。随着创面氧化还原稳态的恢复,敷料进一步调控局部免疫微环境,诱导促炎型巨噬细胞向修复型表型极化,从而解除对血管内皮生长信号通路的抑制。体内外实验结果表明,该体系通过声辅助渗透与电子能级催化平衡的协同作用,实现了抗菌、抗氧化及免疫调节功能的深度整合,促进了糖尿病创面功能性血管网络的重建及皮肤组织再生。

The coexistence of cationic and anionic dyes in wastewater necessitates the development of amphoteric adsorbents. Herein, amphoteric hydrogel microspheres SA-S@PDA-H was successfully fabricated for their simultaneous removal. The microspheres were synthesized by crosslinking sodium alginate (SA) with Ca²⁺, followed by coating with polydopamine (PDA) and stearyl trimethyl ammonium chloride (STAC). The microspheres prepared through acid treatment to replace STAC was labeled SA-S@PDA-H, endowing the microspheres with enhanced adsorption capacity. FT-IR, SEM, zeta potential was utilized to characterize the structure and morphology of SA-S@PDA-H. The adsorption behavior and mechanism of SA-S@PDA-H for cationic and anionic dyes was investigated in depth. The results show SA-S@PDA-H exhibit 127.3 % of swelling ratio. The adsorption of SA-S@PDA-H for MB and MO reaches equilibrium at about 300 min followed by PSO model. The adsorption process of SA-S@PDA-H for MB and MO followed Temkin and Dubinin-Radushkevich model, respectively, and the maximum adsorption capacity displayed 869.1 mg/g at 45°C and 730.9 mg/g at 15°C, for MB and MO, respectively. MB adsorption increased with higher temperature and pH, while MO adsorption increased with lower temperature and pH. Adsorption of both dyes decreased at high ionic strength, and Cu 2 + and Fe 3+ had a significant inhibitory for MB than K + , while the inhibitory effects of SO 4 2- or CO 3 2- is more obvious for MO than Cl - . SA-S@PDA-H exhibited excellent adsorption performance for mixed cationic and anionic dyes through synergistic effects including electrostatic interactions, hydrogen bonds, π-π stacking and micropore filling. The microspheres maintained over 80 % removal efficiency after five consecutive adsorption-desorption cycles.

The long-term clinical success of titanium-based implants is perpetually compromised by post-operative infection and suboptimal osseointegration. To address this dual challenge, we developed a defect-engineered, zinc-doped titania (Zn-TiO 2-x ) coating through a two-step process of micro-arc oxidation and subsequent alkaline reduction. This process endows the material with a profusion of oxygen vacancies (OVs), imparting significant absorbance in the near-infrared (NIR) spectrum. Upon 808 nm laser irradiation, this property translates into highly efficient photothermal conversion, which orchestrates a formidable, multi-modal antibacterial assault. The coatings exhibited exceptional bactericidal efficacy, achieving eradication rates of over 89% against S. aureus and 98% against E. coli . This potency stems from a synergistic trinity of hyperthermia via photothermal therapy (PTT), cytotoxic reactive oxygen species (ROS) generated through photodynamic therapy (PDT), and the intrinsic antimicrobial activity of released Zn 2+ . Concurrently, beyond antimicrobial prowess, the hierarchical porous microarchitecture acts in concert with the pro-osteogenic bioactivity of Zn 2+ to markedly enhance the adhesion, proliferation, and osteogenic differentiation of bone marrow-derived mesenchymal stem cells (BMSCs). This study presents a versatile coating strategy for endowing titanium implants with dual therapeutic capabilities, opening new avenues for smart implants that actively combat infection and promote tissue regeneration.

Titanium, a widely used material for joint replacements and dental restorations, is vulnerable to bacterial infections on its tissue contact surfaces, which can reduce its long-term durability. In this work, TiO 2 nanostructures with varying morphologies were synthesized on titanium surfaces through hydrothermal treatment. The results revealed a transformation of the anatase TiO 2 from nanosheets to nanorods and then to nanowire clusters with increasing treatment time. These nanostructures exhibited superhydrophilicity, increasing surface roughness, excellent photothermal conversion, sustained reactive oxygen species (ROS) release, and significant apatite-forming capability. Importantly, in vitro assays using MC3T3-E1 pre-osteoblast cells confirmed their excellent biocompatibility. Under NIR laser stimulation, the antimicrobial rates of the optimized nanowire cluster structure reached 94.5% against Escherichia coli and 90.5% against Staphylococcus aureus . The results of this study may provide a feasible approach for constructing a physicochemical synergistic antimicrobial system for titanium-based implants with favorable biocompatibility.

Dye-contaminated wastewater from the textile and dyeing industries poses severe environmental and health risks due to the persistence and toxicity of synthetic dyes. To address this issue, sodium alginate (SA)-based composite gel microspheres were fabricated via ionic crosslinking with calcium chloride followed by acid exchange to enhance structural stability and adsorption performance. Two types of functionalized adsorbents were synthesized and optimized: SA modified, and with stearyltrimethylammonium chloride (SA/S-H) and SA co -functionalized with poly(sodium 4-styrenesulfonate) (SA/S/PS-H). Comprehensive characterization using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS) confirmed the successful preparation and compositional uniformity of the adsorbents. Adsorption kinetics for methylene blue (MB) followed the pseudo-second-order model, reaching equilibrium within 6 h， while isotherm data fitted the Dubinin-Radushkevich (D-R) model. Notably, the incorporation of PSSS significantly enhanced the adsorption capacity; at 45 °C, SA/S/PS-H achieved a remarkable maximum adsorption capacity of 900.91 mg/g, compared to 612.61 mg/g for SA/S-H. The dominant adsorption mechanisms were identified as electrostatic attraction, micropore filling and hydrogen bonding. Furthermore, the microspheres showed excellent reusability despite the interference of co-existing cations. This study presents a simple and scalable approach for constructing high-performance bio-based adsorbents with significant potential for sustainable and practical treatment of dye-laden wastewater.

Graphitic carbon nitride (g-C 3 N 4 ) has received much attention as a metal-free polymeric two-dimensional photocatalyst for antibiotic-free antibacterial application. However, the weak photocatalytic antibacterial activity of pure g-C 3 N 4 stimulated by visible light limits its applications. Herein, g-C 3 N 4 is modified with Zinc (II) meso -tetrakis (4-carboxyphenyl) porphyrin (ZnTCPP) by amidation reaction to enhance the utilization of visible light and reduce the recombination of electron-hole pairs. The composite (ZP/CN) is used to treat bacterial infection under visible light irradiation with a high efficacy of 99.99% within 10 min due to the enhanced photocatalytic activity. Ultraviolet photoelectron spectroscopy and density flooding theory calculations indicate the excellent electrical conductivity between the interface of ZnTCPP and g-C 3 N 4 . The formed built-in electric field is responsible for the high visible photocatalytic performance of ZP/CN. In vitro and in vivo tests have demonstrated that ZP/CN not only possesses excellent antibacterial activity upon visible light irradiation, but also facilitates the angiogenesis. In addition, ZP/CN also suppresses the inflammatory response. Therefore, this inorganic–organic material can serve as a promising platform for effective healing of bacteria-infected wounds.

Textiles with efficient and long-lasting antibacterial properties have attracted significant attention. However, a single antibacterial model is insufficient to with variable environments and achieve higher antibacterial activity. In this study, lysozyme was used as assistant and stabilizer, and the efficient peeling and functional modification of molybdenum disulfide nanosheets were realized by ultrasonic. Additionally, lysozyme in the presence of reducing agents to form amyloid-like phase-transited lysozyme (PTL) and self-assembling on the wool fabric. Finally, the AgNPs are reduced in situ by PTL and anchored onto the fabric. It has been demonstrated that Ag-MoS 2 /PTL@wool generates ROS under light irradiation, rapidly converts photothermal heat into generate hyperthermia, and promotes the release of Ag + . The aforementioned “four-in-one” approach resulted in bactericidal rates of 99.996 % (4.4 log, P < 0.0005) and 99.998 % (4.7 log, P < 0.0005) for S.aureus and E.coli , respectively. Even after 50 washing cycles, the inactivation rates remained at 99.813 % and 99.792 % for E.coli and S.aureus , respectively. In the absence of sunlight, AgNPs and PTL continue to provide continuous antibacterial activity. This work emphasizes the importance of amyloid protein in the synthesis and application of high-performance nanomaterials and provides a new direction for the safe and effective application of multiple synergistic antibacterial modes for microbial inactivation.

As an important biomass resource, agricultural waste is of great significance to improve the application value. In this study, the yellow passion fruit peel (Y-PFP) was used as a biosorbent to remove cationic dyes (methylene blue (MB) and methyl violet (MV)) by the simple treatment process. And the effects of pH, contact time, initial dye concentration, ionic strength, and temperature on the adsorption performance of Y-PFP were studied. The adsorption process was consistent with the pseudo-second-order kinetic model and Langmuir isotherm. What’s more, the maximum adsorption capacity for MB and MV was 324.7 and 485.4 mg·g−1, respectively. And Y-PFP still exhibited high removal efficiency after five desorption–adsorption cycles. Thus, Y-PFP had highly valuable for the removal of cationic dyes from wastewater with a simple preparation process, low cost, excellent adsorption capacity and selectivity.

Hydrogel is an ideal biomedical material because of its 3D network structure. However, their applications are greatly limited due to their poor mechanical strength and antibacterial property. Herein, a physically cross-linked and light-responsive poly(vinyl alcohol) (PVA) hydrogel embedded with quaternized chitosan-coated molybdenum disulfide (QCS-MoS 2 ) nanomaterials was successfully prepared. The photothermal performance of QCS-MoS 2 was studied with the results that QCS-MoS 2 could be employed as a superior photothermal agent for light responsive hydrogels. After being incorporated with QCS-MoS 2 , a hydrogen bonding network could be formed in the hydrogel matrix, significantly increasing the mechanical properties. Moreover, the hybrid hydrogels exhibited excellent antibacterial properties. 95.6 % of Staphylococcus aureus ( S. aureus ) and 98.8 % of Escherichia coli ( E. coli ) were killed in 15 min due to the synergistic effects of the high temperature and the reactive oxygen species (ROS) generated by the irradiation of 808 nm near-infrared (NIR) light. No cytotoxicity was found by the introduction of QCS-MoS 2 , suggesting a great potential in photothermal antibacterial application for biomedical materials.

The corrosion of Fe(0) in the presence of O 2 in nature can lead to the oxidation of organic compounds, but the efficiency is very limited. Herein, attempts were made to establish a galvanic system that separates the anodic Fe(0) oxidation reaction and the cathodic O 2 reduction reaction using an air-breathing cathode. Compared with the chemical Fe(0)/O 2 system, it exhibited a substantially higher capability of destroying a variety of pollutants, such as organic dyes (12 types), phenol , nitrobenzene , acetaminophen, phenol, and ethylenediaminetetraacetic acid. The degradation rate constant of a model dye (i.e., Rhodamine B) increased from 0.047 min − 1 (chemical) to 1.412 min −1 (galvanic) under the passive air-breathing condition. The electric circuit design promoted Fe(0) dissolution to Fe(II) and triggered electron transfer that drives O 2 reduction to H 2 O 2 , two important species responsible for the generation of HO • at high abundance. In addition, the galvanic Fe(0)/O 2 system produces electricity while destroying pollutants. Tests with real Ni plating wastewater further demonstrated the capability of the system to oxidize complexed organics and phosphite. This study provides a new strategy for boosting the oxidative capacity of the Fe(0)/O 2 system, which shows promise for acid wastewater treatment .

In this work, the cellulose nanofibers based membranes with both high dye solution flux and rejection rates were obtained. The cellulose nanofibers (PPCNFs) were prepared from pomelo peels by simple H 2 O 2 oxidation process , decorated with ZIF-8 crystals, and vacuum filtrated to form composite membranes (PPCNFs@ZIF x ). Ascribing to the highly porous structures of ZIF-8, as well as their uniform and stable deposition on the surfaces of PPCNFs, the resultant membranes were mechanically strong (tensile strength up to ~72.25 MPa), surface area rich (~ 199.46 m 2 /g), and with a maximal dye solution flux of ~32.3 L m −2 h −1 bar −1 and dye rejection rates larger than 85 % (89.95 % for methyl blue , 98.83 % for methyl violet, 95.91 % for malachite green , 95.36 % for rhodamine 6 G, and a high rejection rate of ~98.6 % toward methyl violet after 30-day cycles). Thus, this work paved a simple and green way to fabricate cellulose nanofibers based membranes with high performance in the remediation of dye contaminated water.
