Loading catalysts onto carriers to prepare supported catalysts is an important strategy for improving dispersion, stability and catalytic performance. In this study, we synthesized a supported red mud (RM)-based Fe-Co Prussian blue analogue (RM-Co PBA) catalyst using RM as iron source and carrier by acid dissolution-reduction-coprecipitation method to activate H 2 O 2 for the degradation of ciprofloxacin (CIP). The RM-Co PBA obtained under the synthesis conditions of HCl concentration of 2.4 M and potassium cobalt cyanide addition of 4 mM exhibited the best dispersibility and regular shape, resulting in high catalytic performance. The degradation efficiency of RM-Co PBA/H 2 O 2 system reached 75.79% in 10 min, which was 10.54 times and 1.21 times of that of RM/H 2 O 2 system and Fe-Co PBA/H 2 O 2 system, respectively. The RM-Co PBA/H 2 O 2 system was almost unaffected by pH and was suitable for treating low concentration CIP wastewater. Additionally, the system can be reused well and possessed certain resistance to inorganic anions. The results showed that superoxide radical (⋅O 2 − ) was the main ROS attacking CIP, which accumulated continuously in the cycling process of Co(III)/Fe(III) and Co(II)/Fe(II). On the other hand, the presence of a large number of oxygen vacancies in RM-Co PBA enhanced the production of ⋅O 2 − by endowing it with good electron transfer performance. Finally, we proposed possible CIP degradation pathways and demonstrated the toxicity reduction of each pathway by a quantitative structure-activity relationship analysis. This study provides guidance for the resource utilization of RM and the efficient treatment of antibiotic wastewater.

A self-signaling electrochemical sensor based on molecular imprinting technology for the detection of Bisphenol A (BPA) in food samples. The sensor was constructed through sequential modification of the electrode with reduced graphene oxide (RGO) and CoNiFe Prussian blue analogue (CoNiFe-PBA), followed by electropolymerization of an MIP film using BPA as template and o-phenylenediamine as monomer. CoNiFe-PBA provides an intrinsic signal at ~ 0.47 V without external probes, originating from synergistic redox interactions among Co, Ni, and Fe. BPA rebinding reduces the signal via steric hindrance, enabling sensitive detection in food samples. Under optimal conditions, the sensor demonstrated a wide linear detection range (0.5–500 nM) and a low detection limit (0.19 nM). Owing to its high selectivity, sensitivity, and accuracy, the sensor offers a reliable approach for precise quantification of trace BPA in complex food matrices. Graphical abstract

Multiplex surface-enhanced Raman scattering (SERS) detection of markers without background in tumor biosystems has its superiority over other optical methods. Herein, we reported a strategy of quantitative discrimination of two breast cancer cell subtypes. Based on our previous studies, two kinds of Prussian blue analogue coated gold nanoparticles ( [email protected] NPs) were designed and synthesized by the replacement of Fe 2+ with Pb 2+ or Cu 2+ . Therefore, two distinct SERS emissions of C≡N bonds at 2122 cm −1 and 2176 cm −1 have been acquired. When modified with aptamers of epithelial cell adhesion molecule (EpCAM) and epidermal growth factor receptor (EGFR), which are both expressed in MCF-7 and MDA-MB-231 cell lines but in different levels, the SERS nanoprobes simultaneously identified the relative expression of these biomarkers on the cell surface, providing a good example for ratiometric detection in biosystems without any interference. Each surface marker of tumor cells corresponds to a single SERS emission. Thus, each subtype could be described in a molecular profiling way through duplex C≡N bonds-based SERS emission, which is more advanced than traditional flow cytometry method.

Background Cartilage injury and pathological degeneration are reported in millions of patients globally. Cartilages such as articular hyaline cartilage are characterized by poor self-regeneration ability due to lack of vascular tissue. Current treatment methods adopt foreign cartilage analogue implants or microfracture surgery to accelerate tissue repair and regeneration. These methods are invasive and are associated with the formation of fibrocartilage, which warrants further exploration of new cartilage repair materials. The present study aims to develop an injectable modified gelatin hydrogel.MethodThe hydrogel effectively adsorbed proteoglycans secreted by chondrocytes adjacent to the cartilage tissue in situ, and rapidly formed suitable chondrocyte survival microenvironment modified by ε-poly-L-lysine (EPL). Besides, dynamic covalent bonds were introduced between glucose and phenylboronic acids (PBA). These bonds formed reversible covalent interactions between the cis−diol groups on polyols and the ionic boronate state of PBA. PBA-modified hydrogel induced significant stress relaxation, which improved chondrocyte viability and cartilage differentiation of stem cells. Further, we explored the ability of these hydrogels to promote chondrocyte viability and cartilage differentiation of stem cells through chemical and mechanical modifications.Results In vivo and in vitro results demonstrated that the hydrogels exhibited efficient biocompatibility. EPL and PBA modified GelMA hydrogel (Gel-EPL/B) showed stronger activity on chondrocytes compared to the GelMA control group. The Gel-EPL/B group induced the secretion of more extracellular matrix and improved the chondrogenic differentiation potential of stem cells. Finally, thus hydrogel promoted the tissue repair of cartilage defects.Conclusion Modified hydrogel is effective in cartilage tissue repair.

Nitroaromatic compounds have a wide range of applications. However, they pose a significant threat to both the environment and human health. Ionic liquid hydrogels (ILs-gels) have emerged as a cost-effective and environmentally friendly option for various applications. However, conventional ILs-gels are known to possess mechanical flaws or defects. The procedure utilized a facile synthesis route that involved the polymerization of acrylamide (AM) and ionic liquids (ILs) to create a novel candidate for nanoparticle absorption. This study resolved this issue by creating toughened hydrophobic combined hydrogels synthesized through the addition of SiO2@poly(butyl acrylate) core–shell inorganic–organic hybrid latex particles (SiO2@PBA) to the AM–ILs mixture. The SiO2@PBA particles were chosen to provide the hydrogels with exceptional stretchability (up to 4050% strain) and high mechanical properties (tensile strength of 126 kPa) by acting as both a nanotoughener and a cross-linking point for hydrophobic linkage. Additionally, the P(AM/ILs)-SiO2@PBA hydrogel served as a template for the in situ and stable formation of palladium (Pd) nanoparticles. By incorporation of these Pd nanoparticles as catalysts into P(AM/ILs)-SiO2@PBA hydrogel carriers, the resulting P(AM/ILs)-SiO2@PBA/Pd hydrogels exhibited the ability to catalyze the degradation of p-nitrophenol. Remarkably, even after 15 applications, the efficiency of the degradation process remained consistently above 90%. Thus, the innovative SiO2@PBA toughened ILs-hydrogel design strategy can be utilized to develop robust and stretchable hydrogel materials for catalytic use in the sewage disposal industry.

In this study, Ni-Fe-based Prussian Blue Analogues (Ni-Fe PBA) served as precursors, giving rise to a NiO/Fe 3 O 4 -based bimetallic catalyst that underwent comprehensive examination for both chemocatalytic water oxidation and photocatalytic degradation of organic dyes. The morphologies and chemical compositions of the precursor and resultant bimetallic catalysts were thoroughly characterized using XRD, SEM, XPS, mapping, and FTIR techniques. The results indicated that the catalytically active center is the NiO/Fe 3 O 4 -based bimetallic nanocomposite. The in-situ-synthesized bimetallic catalyst demonstrated remarkable catalytic oxidation activity when evaluated with Sodium Persulfate (PS) as an oxidant. Oxygen evolution results revealed an impressive catalytic water oxidation activity, with an O 2 production rate of approximately 1594.3 µmol·g −1 ·h −1 . Moreover, the NiO/Fe 3 O 4 catalyst was utilized as a heterogeneous photocatalyst to activate photosensitizer (PS) for the two azo dye’s deterioration caused by the exposure to visible light. Both organic dyes were photocatalytically degraded with great efficiency when Fe 3 O 4 and NiO were combined because they increased the catalyst’s capacity to absorb light. Electron Spin Resonance (ESR) and radical trapping studies revealed that sulfate (SO4· - ) and hydroxyl (OH·) radicals played pivotal roles. The degradation mechanism and pathway for Rhodamine B (RhB) were also elucidated. The exceptional recyclability and stability of the NiO/Fe 3 O 4 catalyst make it particularly promising for potential applications in water treatment, addressing challenges related to energy sustainability and environmental toxicity.

A pretreatment method can simultaneously achieve the removal of the surface passivation layer and vacancy engineering. • The difference in work function drives electron injection, resulting in a redistribution of electrons at the interface. • A multi-scale evidence chain verified the vacancy construction and directional charge transfer in a closed-loop manner. • Ion-intercalation pseudocapacitive storage provides high capacitance, wide voltage window, and persistent ASC performance. Owing to sluggish kinetic processes, the development of high-energy-density supercapacitors still faces major challenges. Herein, a NiSe 2 -Vse@Ni-Co PBA heterojunction synthesized through a sodium borohydride (NaBH 4 ) pretreatment-assisted assembly strategy is reported. The novelty of this work lies in the fact that the NaBH 4 treatment simultaneously depassivates the NiSe 2 surface, introduces a high density of selenium vacancies, and weakens the electrostatic repulsion between NiSe 2 and negatively charged Ni-Co PBA, thereby facilitating closer interfacial contact. Electron paramagnetic resonance (EPR) measurements confirm the successful generation of selenium vacancies. Density functional theory (DFT) calculations further reveal a pronounced work-function difference between NiSe 2 and Ni-Co PBA, while selenium vacancies increase the d-orbital states near the Fermi level in NiSe 2 -Vse. Together, these factors favour directional electron donation from the vacancy-rich NiSe 2 side to the PBA side after interfacial contact. Combined with the XPS results, this interfacial electron redistribution is consistent with the partial reduction of Co species and the markedly improved charge-transfer behaviour. As a result, the optimised electrode delivers a high specific capacitance of 1631.14 F g −1 and retains 80.37% of its initial capacitance after 5000 cycles. The assembled asymmetric supercapacitor operates stably at 1.7 V, achieving an energy density of 52.19 Wh kg −1 at a power density of 739.64 W kg −1 , and maintains 78.71% of its initial capacitance after 5500 cycles. This work shows that a simple pretreatment step can integrate surface depassivation, vacancy engineering, and work-function-driven interfacial electron redistribution into a single heterojunction system, offering a practical route to high-performance supercapacitor electrodes.

The development of novel materials with high-efficiency microwave absorption is crucial for mitigating the adverse impacts of electromagnetic pollution. In this study, MXene and FeNi Prussian blue analogs (PBA) are assembled onto a melamine foam using self-assembly and in situ growth technique. Subsequently, magnetic carbon foam, comprising FeNi alloys, TiN and carbon with various morphologies, is synthesized via carbothermal reduction reaction. The surface morphology electromagnetic properties are significantly influenced by the pyrolysis temperature. The results revealed that the magnetic carbon foam composite demonstrated an effective microwave absorption bandwidth of 4.72 GHz at a thickness of only 1.5 mm, with a minimum reflection loss of −24.83 dB at 1.3 mm. The outstanding microwave absorption performance can be attributed to the 3D conductive network formed by N-doped carbon, as well as the contributions from polarization loss, magnetic loss, and suitable impedance matching. Furthermore, the corresponding absorber coating demonstrated a maximum reduction value of radar cross-section (RCS) by 13.16 dB m 2 . This research offers novel insights for the development of lightweight and efficient low-filled electromagnetic composite for broadband microwave absorption.

Prussian blue analogs (PBAs) have been widely explored as catalyst for peroxymonosulfate (PMS) activation. However, the drawbacks of poor electron transfer ability and degradation performance of PBAs hinder their practical application. In this study, oxygen vacancy (OV)-rich Mn-Fe PBA was regulated through phosphoric acid and ammonia water chemical etching to overcome these drawbacks. Experimental and theoretical investigations indicated that the regulation of OVs was favorable for more Fe 2+ and Mn 3+ active sites exposure and higher specific surface area to facilitate PMS activation. Sulfate radical (SO 4 •− ), hydroxyl radical (HO•), and single oxygen ( 1 O 2 ) were verified as main reactive species for PMS activation during catalytic reaction . Density functional theory calculation results showed that the OV-rich NOE-PC-300 had the highest pollutants degradation capability, with complete degradation of bisphenol A (BPA) and acetaminophen (APAP) within 40 min. Through regulation of OVs by chemical etching, highlighted adsorption ability and elongated O–O bond of PMS were obtained. This research showed that NOE-PC-300 is an efficient and harmless catalyst for activating PMS, and it has immense application potential in practical wastewater treatment .

In recent years, the study of microplastics (MPs) and nanoplastics (NPs) and their effects on human health has gained significant attention. The impacts of NPs on lipid metabolism and the specific mechanisms involved remain poorly understood. To address this, we utilized high-throughput sequencing and molecular biology techniques to investigate how endoplasmic reticulum (ER) stress might affect hepatic lipid metabolism in the presence of polystyrene nanoplastics (PS-NPs). Our findings suggest that PS-NPs activate the PERK-ATF4 signaling pathway, which in turn upregulates the expression of genes related to lipid synthesis via the ATF4-PPARγ/SREBP-1 pathway. This activation leads to an abnormal accumulation of lipid droplets in the liver. 4-PBA, a known ER stress inhibitor, was found to mitigate the PS-NPs-induced lipid metabolism disorder. These results demonstrate the hepatotoxic effects of PS-NPs and clarify the mechanisms of abnormal lipid metabolism induced by PS-NPs.

In the context of escalating global environmental concerns, the pursuit of highly efficient photocatalysts has emerged as a prominent research focus. In this study, PBA-derived CoS₂/FeS was anchored to b-CNTs through hydrothermal and calcination techniques to serve as a Photo-Fenton-like catalyst. The CoS 2 /FeS/b-CNTs exhibited remarkable photocatalytic Fenton activity. Under xenon lamp irradiation, an impressive degradation efficiency of 97% for RhB was achieved within a mere 210 s, concomitantly exhibiting extensive adaptability across a wide pH range of pollutant solutions. Even after three consecutive cycles and magnetic recovery separation procedures, the degradation efficiency of RhB still remains at a high degradation efficiency of 94.6%. Free radical capture experiments unambiguously indicated that singlet oxygen ( 1 O 2 ) and hydroxyl radicals (•OH) played pivotal roles as the principal active species during the degradation process. This research not only pioneers a novel avenue for the design of PBA-derived layered nanostructured photocatalysts but also holds significant potential for future applications in Photo-Fenton-like degradation of recalcitrant organic pollutants, heralding a new era in environmental remediation technology.

A novel glucose sensor was reported that consisted of two-dimensional (2D) Au nanosphere arrays and glucose-responsive hydrogel film. This sensor exhibited an intense diffraction signal and an obvious diffraction color on a quartz slide due to the strong diffraction intensity of the Au nanosphere arrays. Thus, glucose was detected via the variation of diffraction wavelength and diffraction color, without a high reflective mirror. In addition, by introducing poly(vinyl alcohol) (PVA) to crosslink the phenylboronic acid (PBA)-modified hydrogel film, the diffraction wavelength of the 2D Au nanosphere arrays/hydrogel composite film shifted in the same direction in high ionic strength condition. In particular, it showed a nearly linear red-shift when the glucose concentration increased from 0 mM to 20 mM. Moreover, this glucose sensor displayed good reproducibility. The nearly linear response and good reproducibility were highly helpful for improving practical application of this glucose sensor.
