High-performance flexible piezoelectric polymer–ceramic composites are in high demand for increasing wearable energy-harvesting applications. In this work, a strategy combining solid-state shear milling (S3M) and fused filament fabrication (FFF) 3D-printing technology is proposed for the fabrication of high-performance biomimetic wearable piezoelectric poly(vinylidene fluoride) (PVDF)/tetraphenylphosphonium chloride (TPPC)/barium titanate (BaTiO3) nanocomposite energy harvesters with a biomimetic fish-scale-like metamaterial. The S3M technology could greatly improve the dispersion of BaTiO3 sub-micrometer particles and the interfacial compatibility, resulting in better processability and piezoelectric performance of the nanocomposites. Typically, the FFF 3D printed energy harvester incorporating 30 wt % BaTiO3 showed the highest piezoelectric outputs with an open-circuit voltage of 11.5 V and a short-circuit current of 220 nA. It could hence drive nine green LEDs to work normally. In addition, a 3D-printed biomimetic wearable energy harvester inspired by an environmentally adaptive fish-scale-like metamaterial was further fabricated. The fish-scale-like energy harvester could harvest energy through different deformation motions and successfully recharge a 4.7 μF capacitor by being mounted on a bicycle tire and the tire’s rolling. This work not only provides a 3D printing strategy for designing diversified and complex geometric structures but also paves the way for further applications in flexible, wearable, self-powered electromechanical energy harvesters.

A novel magnetic hyper crosslinked polymer (BTA-MHCP) was prepared by one-pot reaction of benzotriazole, 1,3,5-triphenylbenzene and phenyl-functionalized Fe 3 O 4 @SiO 2 . The BTA-MHCP was then investigated as the adsorbent for the rapid magnetic solid-phase extraction (MSPE) of the 5-nitroimidazoles (5-NDZs) including dimetridazole, metronidazole, secnidazole, ronidazole and ornidazole. The adsorbent showed good adsorption properties for the 5-NDZs. The key factors that affect the MSPE such as extraction time, the amount of sorbent, and the type of eluent and its volume were optimized. Under the optimal conditions, the linear response ranges for the established method were 0.15–100.0 ng mL −1 and 3.9–100.0 ng g −1 for drinking water and fish samples, respectively, with the coefficients of determination ( r 2 ) of 0.9981 to 0.9998. The limits of detection (S/N = 3) for the analytes were 0.02–0.05 ng mL −1 and 0.7–1.3 ng g −1 , and the method recoveries ranged from 92.0% to 101.0% and from 89.9% to 104.0% for drinking water and fish samples, respectively.

The global food waste problem, especially aquatic product spoilage, stimulates the accurate freshness analysis of food products. However, it still remains a great challenge to realize in-field determination of fish freshness at the time of use. In the present study, a colorimetric enzyme biosensor was developed for one-step detection of hypoxanthine (Hx), which is an important intermediate of adenosine triphosphate decomposition during fish storage. We demonstrate that xanthine oxidase grade I ammonium sulfate suspension (XOD-ASS) possesses peroxidase activity. It can oxidize different peroxidase substrates, including 3,3′,5,5′-tetramethylbenzidine, 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt, and o-phenylenediamine in the presence of H 2 O 2 , producing visible color reactions. Further experiments indicate that XOD-ASS displayed effective peroxidase activity and could be used for H 2 O 2 detection. Based on this, a one-step Hx detection method was established using only XOD-ASS as the catalyst. The method displays a good linear relationship in the range from 20 to 100 μM with a detection limit of 6.93 μM. Additionally, we successfully applied this method in testing Hx accumulation in sea bass fish samples of different storage times. The recovery values range from 97.44 to 102.56%. It is exciting to note that, compared with other methods, our proposed method provides a robust advantage on the economic reaction system, ease of preparation, short time consumption, and moderate reaction temperature. We believe that this method shows good application prospects for on-site fish freshness determination.

A magnetic fluorescence probe was fabricated by coating carbon quantum dots-doped molecularly imprinted polymers (MIPs) layers on the surface of Fe 3 O 4 particles (MFMP) for detection of N -acyl homoserine lactones (AHLs) signaling molecules. N-Z- L -homoserine lactone molecular was used as the template to prepare AHLs MIP layers, employing MAA and HEMA as functional monomers. The developed MFMP owned superparamagnetism, fluorescence, fast response and class-selectivity. If AHLs (C 4 -HSL, C 6 -HSL, C 8 -HSL, C 10 -HSL, C 12 -HSL and C 14 -HSL) were captured by the MFMP, they quenched the fluorescence of the probe. Fluorescence dropped linearly in the concentration ranges of 3.65 × 10 −3 μmol/L–0.96 × 10 −1 μmol/L for AHLs. The MFMP was applied to the analysis of fish juice and milk samples, and recoveries ranged from 83.10% to 90.74% with relative standard deviation less than 5.1%. This study offered a novel strategy to fabricated AHLs fluorescence probe with great potential for wide-ranging application in agri-food products.

The development of efficient, facile and stable approach to separate water from oilfield emulsified oily wastewater is highly desired. In our work, inspired by oil-repellent property of fish scales with a thin layer of mucus and hierarchical structures, pioneering fish-scale-like CuC 2 O 4 nanosheets wrapped (i.e., CuC 2 O 4 NSW) on copper mesh surfaces were fabricated by a facile in-situ chemical etching. The unique vertically grown crisscross CuC 2 O 4 nanosheet layer delivered a strong water capture ability to form a firm water film for achieving rapid and super oil repellence functionality. The 300-mesh CuC 2 O 4 NSW copper mesh exhibited superior underwater superoleophobicity and was proven to treat emulsified oily wastewater effectively (with a water permeation flux being circa 2200 L·m −2 ·h −1 and COD value in filtrate at circa 54 mg·L −1 ). Furthermore, the 500-mesh CuC 2 O 4 NSW copper mesh was demonstrated to effectively separate surfactant-stabilized oil-in-water emulsions (with a water permeation flux of 1000–2000 L·m −2 ·h −1 and COD value in filtrate < 55 mg·L −1 ). The good chemical, mechanical and thermal stability of the as-prepared mesh was further ascertained by different stability tests. With the efficient separation capability, good underwater super oil-repellent and self-cleaning abilities, the novel membrane prepared by the easily scaled-up method shows great potential for industrial applications.

A new, sensitive, and rapid method based on the Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) approach and air-assisted liquid-liquid microextraction (AALLME) technology was developed for the determination of 20 endocrine-disrupting compounds (EDCs) in fish by high-performance liquid chromatography–tandem mass spectrometry. The method first integrates AALLME into QuEChERS to achieve clean-up and enrichment of the EDCs in one step. A self-made glass tube was enfolded with plasticine to withstand the high centrifugal force. The established method was developed by optimization of the parameters. High linearities (R 2 > 0.9924) and recoveries (78.2–118.6%) at three spiked levels (5, 10, and 20 ng g −1 ), and low relative standard deviation values (1.1–14.5%) and limits of detection (0.03–0.80 ng g −1 ) were obtained. The method comparison shows that the proposed method is superior as it involves less organic solvent usage, simple operation and high efficiency. This method was successfully applied to different fishes for analyzing EDCs.

A fluorescent probe based on CdTe quantum dots (QDs) coated with molecularly imprinted polymers (MIPs) was fabricated for the determination of malachite green (MG) by the strategy of fluorescence resonance energy transfer (FRET). The MIP-coated QDs were synthesized through precipitation polymerization using acrylamide and ethylene glycol dimethacrylate as monomer and cross-linker, respectively. The optimum molar ratio of MG, monomer and cross-linker was 1:8:40 in 60 mL of acetonitrile, and the polymerization time was 28 h. The MIP-coated QDs, with an average diameter around 290 nm, showed excellent fluorescence emission in 500–700 nm at λ ex 370 nm. The probe exhibited fluorescence quenching response to MG selectively within only 5 min at the concentrations from 0.1 to 20 μmol L −1 . The fluorescent probe was successfully used to detect MG in water and fish samples with a detection limit of 0.059 μmol L −1 (3 σ , n = 9). The spiked recoveries, from 94.8% to 98.1% for water samples, and 98.1% to 106.2% for fish samples, respectively, indicated that the as-prepared MIP-coated QDs could be used as a fluorescent probe to detect MG rapidly in water and fish samples.

The traditional gelatin extraction methods (acid-base) may hinder to their green applications due to mass energy consumption and pollution. Herein, we constructed a clean and sustainable gelatin extraction method, investigated the molecular mechanism of microwave treatment (0–360 min) and freeze-thaw on the gelatin extraction from the perspective of the crosslinking degree and hydrogen bonds. Microwave (0–60 min) can improve the hydrolysis degree (DH) and expose more enzyme cleavage sites of collagen by destroying the intramolecular and intermolecular covalent crosslinking. Freeze-thaw loosened the collagen structure mainly by destroying hydrogen bonds, further increased degree of freedom, DH and enzyme cleavage sites, improved the gelatin yield and gel strength. However, the long-term microwave treatment (60–360 min) severely damaged the covalent crosslinking, increased the DH and enzyme cleavage sites. Freeze-thaw further loosened the collagen structure, caused the rapid dissolution and degradation of subunit, improved the gelatin yield and reduced the gels strength.

This study aimed to develop a natural colorimetric aerogel based on carboxymethyl cellulose (CMC), sodium alginate (SA), black goji anthocyanin (BGA), and various natural fibers such as cotton fiber (CF), silk fiber (SF), and down fiber (DF) via a freeze-drying approach for monitoring fish freshness. Various colorimetric aerogels, including CMC/SA, CMC/SA/CF, CMC/SA/SF, and CMC/SA/DF were developed and structurally characterized using SEM, FTIR, XRD, TGA, TPA, and BET. CMC/SA aerogel showed higher density (0.054 g/cm 3 ) with no surface pores, while CMC/SA/SF had a large surface area (18.6214 m 2 /g) with uniformly higher porosity (97.113 %) and a lower density (0.024 g/cm 3 ). Moreover, the CMC/SA/SF aerogel exhibited higher mechanical properties and color sensitivity at various pH compared to other aerogels, which was then used as an indicator label for monitoring fish freshness during storage at 4 °C and 25 °C. The label aerogel became blue from purple, when TVB-N and pH values reached 20.03 mg/100 g and 19.50 mg/100 g and pH 6.67 and 6.67 at 4 and 25 °C, respectively, exhibiting fish deterioration. Taken together, the colorimetric aerogel composite CMC/SA/SF shows great potential for application as an intelligent package in monitoring the freshness of fish.

With the wide application of phthalic acid esters (PAEs) in the manufacturing of plastic products, a large number of PAEs were discharged into marine ecosystem and accumulated in fish, which has posed a serious threat to marine ecological environment and fishery resources. However, the bioaccumulation of PAEs in fish in mangrove ecosystem, the most productive marine ecosystem, has not been well characterized. In this study, dominant fish and their potential food sources (including particulate organic matter (POM), sedimentary organic matter (SOM), Metapenaeus ensis (Shrimp) and Oreochromis (Ore) were collected from Dongzhai Harbor, a typical mangrove ecosystem. The concentrations of nine PAEs in fish and their potential food sources were determined. Then stable nitrogen and carbon isotope analysis, combined with a new Bayesian mixing model (MixSIMMR) was used to quantify the diet compositions of fish and elucidate the effect of dietary habit on PAEs bioaccumulation in fish. The results indicated that the median concentration of ∑ 9 PAEs in fish was 1119 μg/kg ww, positioning it at a moderate to low level in comparison to other regions. di-n-butyl phthalate (DBP) and diisononyl ortho-phthalate (DINP) were the dominant PAEs in fish. The PAEs concentration in demersal fish was significantly higher than that of pelagic fish, which may be attributed to the substantial contributions of shrimp (28.5 %) and POM (25.3 %) to the diet of demersal fish. This study provided new insights on the bioaccumulation of PAEs in dominant mangrove fish and confirmed that habitat preferences and food sources could significantly influence the bioaccumulation of PAEs in fish.

Crystal violet (CV) residues in Marine food have produced a severe health threat in human life. In this study, we proposed a semiconductor surface-enhanced Raman scattering (SERS) sensor of corrosion-resistant Polyaniline/Graphene oxide (PPy/GO) film by electrochemical growth method to detect CV residues in fresh fish tissue. A PPy/GO dispersion solution was one-step deposited on a stainless steel sheet surface by electrochemical polymerization process to form a PPy/GO composite film acting as a semiconductor SERS substrate. Since the substrate of PPy/GO film was mainly composed of GO sheet without other metals, it had a good corrosion resistance. The SERS enhancement factor and charge transfer intensity P CT of PPy/Go SERS substrate for CV molecules were up to 1.18 × 10 6 and 0.903, respectively. Furthermore, the limit of detection ( LOD ) of PPy/GO SERS substrate could reach 1.58 nM. In addition, SERS sensor of PPy/GO film could identify CV residues in fresh fish tissues, and its recovery rate was 91.8 %–107 %. This preparing method and detecting method we proposed PPy/GO SERS substrate provide a new pathway for detecting CV residues in Marine food.

In this study, an efficient and practical method was established to enrich and detect three trace quinolones in fish tissue. Low-cost and environment-friendly cotton threads were coated with PCN-224 using a simple one-pot hydrothermal method. The PCN-224-modified cotton threads (PCN-224@CTs) were characterized to ensure that the crystal was successfully fabricated on the surface of cotton threads. The prepared PCN-224@CTs were wrapped around steel needles to form suspended bars. Key factors of extraction and desorption were optimized, and analytical performance was tested. Suspended bar sorptive extraction coupled with ultra-performance liquid chromatography (UPLC) with a photodiode array detector was used to analyze the quinolones in fish tissue. The detection limits of quinolones were 0.26–1.15 ng/mL, and the recoveries were achieved in the range of 81.31%–115.81%, indicating a simple method with high sensitivity and satisfactory practicability of enriching, separating, and detecting trace quinolones was successfully established.
