Small-sized platinum nanoparticles (Pt NPs) exhibit high peroxidase-like activity but suffer from self-agglomeration and poor stability. To solve this problem, using porous aminophenol formaldehyde resin (APF) microspheres as a support, a sulfhydryl-functional Pt NPs-based hybrid nanozyme (APF@Pt NPs) with excellent peroxidase-like activity was designed by anchoring Pt NPs on the surface of APF. High specific surface area and abundant active groups of APF microspheres facilitate the uniform distribution of Pt NPs. This design not only enhances the dispersibility of Pt NPs to prevent aggregation but also exposes more active sites─key factors that contribute to the improved catalytic performance of APF@Pt NPs. Using APF@Pt NPs as a recognition element, a sensitive colorimetric method was developed for mercury ion (Hg2+) detection through specific inhibition of Hg2+ on the peroxidase activity of APF@Pt NPs. This sensor exhibited good linearity (R2 = 0.952) in the range of 0–3.125 μM. The limit of detection (LOD) was as low as 0.096 μM, along with satisfactory recoveries of 98–115% and relative standard deviation (RSD) < 3.75% in real water. Integrated with a hydrogel-sensor and smartphone APP, a real-time and visual intelligent sensing platform enabled a rapid qualitative and quantitative analysis of Hg2+ by RGB analysis in environmental samples. These findings illustrate that the application of APF@Pt NPs provides an effective support-engineered strategy to enhance and regulate the peroxidase-like activity and stability of small-sized Pt NPs. This also presents a multifunctional sensing platform for on-site and real-time monitoring of heavy metals in complex environmental samples.

Methylene blue (MB), acid fuchsin (AF), and divalent copper ions (Cu2+) are common aquatic pollutants known for their environmental persistence and biotoxicity, posing considerable risks to ecosystem integrity and human health. Therefore, developing efficient adsorbents for their elimination is crucial. In this study, an asymmetric concave polymer was synthesized through a one-step self-assembly method employing 3-aminophenol (3-AP) as the monomer, formaldehyde as the cross-linker, and ammonia as the catalyst, and then subjected to etching with acetone to refine its concave structure. The polymer demonstrated outstanding synchronous adsorption performance in both Cu2+/AF and AF/MB binary systems, achieving maximum adsorption capacities of 473.5 mg/g for MB, 1250.6 mg/g for AF, and 988.64 mg/g for Cu2+. The adsorption behaviors of AF and Cu2+ conformed to the Langmuir model, implying monolayer, spontaneous, and endothermic chemisorption. While MB adsorption was more accurately represented by the Freundlich model, reflecting a heterogeneous surface-based, spontaneous, and endothermic process. The adsorption kinetics for all three contaminants were best described by the pseudo-second-order model, affirming chemisorption as the rate-controlling step. These results reveal that the asymmetric concave adsorbent functions through a synergistic mechanism involving electrostatic attraction, hydrogen bonding, and chemical complexation. This study underscores the material’s wide application potential in treating complex water pollutants.

Regulating the motion speed of photothermally driven nanorobots remains a significant challenge, as relying solely on a single thermal gradient often fails to provide sufficient driving force differentials for effective speed-switching. Herein, inspired by the thermo-responsive phase-change behavior of organics, we report a thermal switch-activated variable-speed nanorobot based on an aminophenol-formaldehyde concave asymmetric hollow nanobowl. By co-encapsulating ammonium bicarbonate as a chemical fuel and 1-tetradecanol as a phase change material, the designed nanorobot (denoted as AB/AF@TD) possesses a thermo-activated switch for speed control. Under 1.0 W/cm 2 NIR irradiation, 1-tetradecanol provides an endothermic buffer that limits the photothermal temperature, resulting in a low-speed level driven primarily by self-thermophoresis. Conversely, higher-power NIR irradiation (2.0 W/cm 2 ) triggers the phase transition of 1-tetradecanol, inducing rapid temperature elevation and the subsequent decomposition of ammonium bicarbonate. The generated microbubbles propel the nanorobot to a high-speed level through a synergistic effect with self-thermophoresis. Accordingly, AB/AF@TD exhibits three distinct motion levels containing Brownian motion, low-speed level (5.4 μm/s), and high-speed level (13.5 μm/s). The high-to-low velocity ratio is 2.5, significantly outperforming the 1.4 ratio of the aminophenol-formaldehyde control nanorobot (denoted as APFC). Benefiting from accelerated mass transfer and the chelating and redox activities of surface phenolic hydroxyl and amino groups, AB/AF@TD achieves 95.6% removal of 20 mg/L aqueous Cr(VI) within 30 min, a removal efficiency 1.2 times that of APFC. These results offer implications for the motion control of nanorobots and emphasize their potential in smart environmental remediation.

Sound-absorbing materials prepared with plant fibers have received extensive attention and research since noise is an urgent environmental problem that needs to be solved; however, there is still room for improvement in the sound absorption performance and flame retardancy of these materials. This study carried out functional modification on plant fiber, flame-retardant plant fiber (FrSF), and investigated their effects on the sound absorption and flame retardancy properties of biomass sound-absorbing composite (BSC). When the addition of FrSF was 30%, the maximum sound absorption coefficient (α max ) of the BSC using FrSF was 0.97 at 1530 Hz, and the noise reduction coefficient (NRC) was 0.40. Meanwhile, FrSF could improve the BSC’s flame-retardant performance with less addition of flame retardant. The limiting oxygen index (LOI) of BSC using FrSF was 29.9%, and the total heat release (THR) decreased 57.62% compare with the BSC using E-glass fiber. This work has made practical contributions to the functional modification of plant fibers and the development of plant fiber-based functional materials. Graphical abstract

Dumbbell-shaped Janus particles with asymmetric morphology, completely separated hydrophilic and lipophilic regions, and acidic/basic dual pH-responsive functional groups (DHL-ABR JPs) are in high demand because they can endow Pickering emulsions with excellent stability and flexible switching ability between emulsification and demulsification by simply changing pH value of the system. Herein, we propose a novel “oil–water interface growth” strategy to directly access 3-aminophenol- co -formaldehyde@SiO 2 (3-APF@SiO 2 ) DHL-ABR JPs with average particle size of ∼250 nm and size distribution index of 0.012. The formation mechanism was systematically investigated. Interestingly, the particle morphology could be precisely tuned from dumbbell to hamburger, and then to popcorn by simply changing the dropping time of tetraethyl orthosilicate. Additionally, the snowman-shaped particles, consisting of SiO 2 and poly (acrylic acid- co -butyl acrylate) at two ends respectively, were prepared via this method. Remarkably, the Pickering emulsion stabilized by 3-APF@SiO 2 DHL-ABR JPs showed excellent emulsification effect, i.e. the oil droplet diameter and emulsification index of the Pickering emulsion remained almost unchanged even after storage for one year and sensitive dual pH-response characteristics, i.e., emulsified at pH = 7, and demulsified at pH = 4 and 10. It is believed that this work paves a new avenue for synthesis and application of various asymmetric nanoparticles.

Phosphatidylserine (PS) is a high-value phospholipid in functional foods and pharmaceuticals. However, the lack of a suitable biocatalytic system has limited the conversion efficiency. A novel Pickering interfacial biocatalysis (PIB) system has developed for converting phosphatidylcholine (PC) to PS in this work. Three immobilized enzyme carriers were synthesized by grafting different modifying groups onto hollow mesoporous silica particles (HMSP). The combination of NQ-62 and octyl-modified groups yielded the optimal immobilized enzyme, PLD@HMSP-N 3 /C 8 . It stabilized the water-in-oil Pickering emulsion and enhanced phospholipase D (PLD) stability via hydrogen bond interactions. Under optimized conditions, a PS conversion of 93.8 % was achieved within 20 min at 40 °C, achieving a catalytic efficiency (CE) of 372 mmol/(g·h). The immobilized PLD demonstrated markedly enhanced thermostability, pH resistance, and protease hydrolysis stability compared to its free and homologous series counterparts. Moreover, it retained 70.9 % of the PS conversion after 10 cycles of reuse.

Capacitive deionization (CDI) is widely regarded as a promising water treatment technology, in which electrode materials are crucial for determining the CDI performance. Recently, bacterial cellulose (BC) stands out as an ideal precursor for fabricating CDI electrodes owing to its unique nanofiber network and sustainability. In this work, utilizing BC as both the carbon source and structural matrix, with sodium phytate (SP) being added as a phosphorus source to induce cross-linking, the BC/SP-derived carbon aerogels served as a P-doped skeleton. Following the incorporation of nitrogen-enriched carbon nanospheres (N-CNS) to optimize pore distribution and enhance surface reactivity, a BC-based composite carbon aerogel (BSNCA Y ) was successfully fabricated. By adjusting the N-CNS/SP mass ratio, the optimal BSNCA 1.5 possesses a high specific surface area (3014.22 ± 5.23 m 2 ·g −1 ) and remarkable wettability, thus delivering an impressive desalination capacity of 29.70 mg·g −1 , a rapid salt adsorption rate of 3.31 mg·g −1 ·min −1 , and excellent cycling stability. Besides, density functional theory calculations further reveal that the synergistic effect of N and P doping enhances the electrosorption capacity toward Na + and Cl − ions. Hence, this work offers new insights into the design and synthesis of innovative BC-based composites, thereby demonstrating the viability as electrode materials for energy storage devices.

Heavy metal pollution in water poses severe threats to ecosystems and human health, demanding urgent development of efficient and sustainable adsorbents. Herein, we report a novel amino-functionalized phenolic resin (APF) synthesized via a facile self-assembly strategy using 3-aminophenol and formaldehyde. This approach eliminates the need for toxic crosslinkers or complex post-modification steps, offering a green and scalable route for nanoscale polymer fabrication. The APF particles were engineered with controlled amino group density and hierarchical porosity through optimizing monomer ratios, achieving abundant active sites for multi-metal interactions. The APF adsorbent exhibits exceptional adsorption capacities for both cationic and anionic heavy metals, notably achieving 297.75 mg·g −1 for Cd 2+ – surpassing conventional clay composites and rivaling advanced MOFs. Its multifunctional groups (–NH 2 , –OH) enable synergistic mechanisms: (1) electrostatic attraction for Cr 6+ oxyanions at low pH, (2) chelation-dominated Cd 2+ capture via amino coordination, and (3) ion exchange for Pb 2+ /As 3+ . This work advances the design of cost-effective, multi-mechanistic adsorbents for comprehensive heavy metal remediation.

A persistent challenge in photothermal conversion elastomers (PTCEs) is simultaneously achieving high photothermal conversion efficiency and robust mechanical properties. Herein, an efficient strategy, constructing extended conjugate structure at the interface of matrix and filler, was developed. Specifically, caterpillar-like Janus particles (CJPs), composed of alternating 3-aminophenol-formaldehyde copolymer bulb and SiO 2 bulb, were first synthesized using an oil-water interface growth and assembly method. These CJPs were then integrated into an aqueous polyurethane matrix through imine bond that was formed by the condensation of amine group on the particle and aldehyde group on the matrix. Interestingly, the interfacial imine bonds are playing three roles, i.e. , facilitating uniformly dispersing of the fillers, bridging the benzene rings existing in the matrix and the filler, and endowing the PTCEs with self-repairing properties. Consequently, the obtained PTCEs exhibited both excellent mechanical properties (tensile strength of 29.63 MPa and elongation at break of 1602%) and high photothermal conversion efficiency (86.79%). This synergistic performance enables the PTCEs to act as next-generation solutions for practical applications including photothermal generators and reversible adhesive tapes. In general, this work not only establishes a new application direction for the Janus particles, but also provides a design guideline for high-performance of PTCEs.

Intestinal vaccination faces several key challenges, including limited epithelial interaction, inefficient antigen uptake, and insufficient immune stimulation. Here, we developed a virus-inspired oral nanovaccine based on spiky mesoporous silica nanoparticles (VMSNs) functionalized with Rehmannia glutinosa polysaccharide (RGP), a natural polysaccharide with favorable intestinal biocompatibility. The resulting RGP-VMSN showed enhanced intestinal retention and epithelial interaction and was associated with increased antigen accessibility within the mucosal environment, reflected by stronger antigen-associated signals at mucosal immune sites. Using ovalbumin (OVA) as a model antigen, oral OVA@RGP-VMSN vaccination was associated with increased intestinal dendritic cell activation, enhanced germinal center responses, and elevated antigen-specific antibody production, together with coordinated mucosal and systemic immune responses. Furthermore, immunization with a Salmonella enterica serovar Typhimurium lysate-loaded nanovaccine improved protection in a murine challenge model. Overall, this strategy represents a promising platform for oral and mucosal nanovaccine development.

Novel catalysts of strongly coupled nickel-cobalt nitrides/carbon nanocage (NiCoN/C nanocages) with good water solubility and low cost are utilized to simultaneously catalytically reduce three nitrophenol isomers (2-NP, 3-NP and 4-NP) into corresponding aminophenol (2-AP, 3-AP and 4-AP) within nearly 5 min at room temperature . It is the first report that only one reagent (dopamine) can achieve fast discrimination of three nitrophenol isomers one by one. The reduced product of 3-NP (3-AP) can selectively form fluorescent substance with dopamine with maximum emission wavelength at 465 nm. The reduced product of 4-NP (4-AP) can selectively react with dopamine to form purple solution with absorption peak at 550 nm. It achieves fluorescent detection of 3-NP from 50 nM to 1.2 μM with the limit detections (LOD) of 17 nM for 3-NP, and colorimetric detection of 4-NP from 5 μM to 200 μM with LOD of 1.7 μM. It also realizes nitrophenol detection in tap water. When 0.30, 0.60, 1.00 μM 3-NP and 10, 50, 100 μM 4-NP are added to water samples, recoveries are 98.8–104.6% for 3-NP and 98.8–101.8% for 4-NP.

In recent decades, magnetic nanomaterials with fast separation and recyclable performance have raised great interest for broad applications in catalysis, protein separation and immunodiagnostics. In this paper, Fe 3 O 4 nanoparticles with a size of (350 ± 50) nm were produced by the solvothermal method. Then, the nanoparticles were coated with a shell made of 3-aminophenol-formaldehyde (APF) resin to prevent agglomeration. The reaction was very rapid, and core–shell Fe 3 O 4 @APF nanospheres were produced by polycondensation within 10 min. Besides, the thickness of the APF shell could be easily adjusted in the range of 10–200 nm by controlling the reaction time and the concentration of 3-aminophenol and formaldehyde. In particular, the APF layer could also act as an effective carrier and reducing agent to capture hundreds of well-dispersed Ag nanoparticles for the abundant hydroxyl groups, obtaining sesame-ball-like Fe 3 O 4 @APF@Ag nanocomposites. The structure of sesame-ball can prevent silver nanoparticles from agglomerating, and Fe 3 O 4 core could provide strong magnetism. The magnetic Fe 3 O 4 @APF@Ag nanomaterials could catalyze the reduction of organic dyes (4-NP, MB and RhB), and the catalyst possessed high activity, with the conversion of dyes remaining above 90% within 3 min after 7 cycles.
