Main conclusion Carbon dots (CDs) have attracted more and more attention due to their low toxicity, good biocompatibility and easy preparation. However, synthesis of CDs with high quantum yield using green and economic method is still challenging. Herein, an effective synthesis route was reported for green synthesizing CDs using waste chicken eggshell membrane as carbon source via microwave-assisted method. The obtained CDs showed good photo-stability with a high quantum yield of 19.5%. The as-prepared CDs was designed as a fluorescent probe for facile, rapid, sensitive determination of theophylline (TP) based on the fluorescence turn on–off strategy. The designed method exhibited good performance for the determination of TP. Under the optimal conditions, the fluorescent response of CDs was proportional to the TP concentrations in the range of 0.1–1 and 1–1000 μM with limit of detection of 28 nM. Moreover, the proposed method was applied to detect the TP content in tea samples. The as-prepared CDs provide a green and economic approach for the food safety test.

Dealing with water pollution is always a challenging task with the rapid development of society. The treatment of industrial wastewater usually requires the efficient and simple methods to reduce the harm to humans and the environment, and the complexity of the types of pollutants in the wastewater is a major challenge. Herein, eggshell membrane (ESM), a kind of agricultural waste with special hierarchical and porous structure, is considered as a promising bio-template for the successful fabrication of ESM-derived magnetic CuFe 2 O 4 nanocomposite (defined as ESM/CuFe 2 O 4 ). The nanocomposite exhibits unique morphological characters with 3D coral-like layered multi-channel architectures, which is completely different from that of pure CuFe 2 O 4 . Intriguingly, the magnetic ESM/CuFe 2 O 4 can be used as a multi-functional material with enhanced adsorption, catalysis, and antibacterial performances for water remediation. The adsorption behavior of the ESM/CuFe 2 O 4 to Congo red follows the pseudo-second-order kinetic model and the Freundlich adsorption isotherm with high correlation coefficients , and the maximum adsorption capability was determined to be 199.23 mg/g. The ESM/CuFe 2 O 4 nanocomposite also displays the good catalytic activity and high recycling stability towards the reduction of 4-nitrophenol, and the degradation rate was reach up to 98.9 % only within 5.5 min, which is superior to some reported materials. Furthermore, it is demonstrated that the magnetic ESM/CuFe 2 O 4 nanocomposite possesses strong antibacterial properties against Escherichia coli ( E. coli ) and Staphylococcus aureus ( S. aureus ). In addition, some effect factors, which play an important role in enhancing the performances, are also discussed. This study provides a cost-effective approach for fabrication of advanced “green” nanomaterials with excellent performances by adding agricultural waste-eggshell membrane for water remediation.

In the present work, we synthesized CuO-ZnO (CZ) nanocomposites using a bio-templated method from biowaste-eggshell membranes (ESM). Results showed that CZ-ESM nanocomposites of morphology and structure preserved the original structural characteristics of ESM with interlaced network coated by small inorganic nanoparticles. In addition, the samples exhibit excellent adsorption, catalysis and antibacterial activities. Experimental results showed the adsorption kinetics and isotherm were well described by pseudo-second order kinetics and Langmuir isotherm model for Congo red dye, the maximum adsorption capacity was determined to be 775 mg•g −1 . The catalysis reduction efficiency of CZ-ESM nanocomposites for 4-nitrophenol (4-NP) reached 98% after 12 min at room temperature. CZ-ESM could be recycled several times without any significant activity loss. Furthermore, the results of antibacterial experiments indicated that CZ-ESM nanocomposites exhibited a strong inhibition activity against E. coli and S. aureus . The maximum diameter of the inhibition zone was 27.5 mm for S. aureus and 20.3 mm for E. coli .

We reported the fabrication of an in situ surface-enhanced Raman scattering (SERS) monitoring platform, comprised of a porous eggshell membrane (ESM) bioscaffold loaded with Ag nanoprism via an electrostatic self-assembly approach. The localized surface plasmon resonance (LSPR) property of silver nanoprism leads to the blue color of the treated ESMs. UV-vis diffuse reflectance spectroscopy, scanning electron microscope (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) measurements were employed to observe the microstructure and surface property of Ag nanoprisms on the ESMs. The silver nanoprism-loaded eggshell membrane (AgNP@ESM) exhibited strong catalytic activity for the reduction of 4-nitrophenol by sodium borohydride (NaBH4) and it can be easily recovered and reused for more than six cycles. Significantly, the composites also display excellent SERS efficiency, allowing the in situ SERS monitoring of molecular transformation in heterogeneous catalysis. The results indicate that the AgNP@ESM biocomposite can achieve both SERS and catalytic functionalities simultaneously in a single entity with high performance, which promotes the potential applications of ESM modified with functional materials.Keywords:eggshell membrane;silver nanoprism;catalysis;SERS

Eggshell membrane (ESM) is an industrial waste that is available in abundance from food industry. Present study investigated the physicochemical properties of oxidized ESM and compared the efficiency of ESM and oxidized ESM as carrier for Burkholderia cepacia lipase (BCL) used in esters hydrolysis and transesterification . Following oxidation treatment, FTIR analysis and Ellman’s assay showed amino acid cysteine in ESM was oxidized to form disulfide bond-containing cystine . In addition, AFM analysis showed ESM which exhibited a highly porous filamentous structure appeared to be coalesce following oxidation treatment. Oxidized ESM also showed reduced porosity (38.67%) in comparison to native ESM (51.65%). BCL were successfully immobilized on oxidized ESM through carrier activation method (enzyme loading of 5.01 mg protein/g oxidized ESM). These immobilized lipase demonstrated significantly (P < 0.05) enhanced catalytic stability with close to 100% of initial hydrolysis (12.03 ± 0.29 mmol/min/g) activity; and more than 85% of its initial transesterification (7.83 ± 0.05) activity for at least 10 consecutive runs. Enhanced catalytic stability of BCL immobilized on oxidized ESM might be due to stabilization of the protein structure in oxidized ESM by disulfide bonds which helped formation of a stable bonding with BCL.

In this study, a facile one-step synthesis of a novel nanocomposite catalytic film was developed based on silver nanoparticles (AgNPs) immobilized in tannic acid-modified eggshell membrane (Tan-ESM). Tannic acid, as a typical plant polyphenol from oak wood, was first grafted onto ESM fibers to serve as both the reductant and the stabilizer during the synthesis of AgNPs. The morphology, constitution, and thermal stability of the resulting AgNPs@Tan-ESM composites were fully characterized to explain the excellent catalytic efficiency of AgNPs@Tan-ESM composites. These composite catalysts were applied to the degradation of azo dyes which exhibited the high catalytic activity toward Congo red and methyl orange according to the kinetic curves. More importantly, they can be easily recovered and reused for many times because of their good stability.

Membranes with super-wettability have been widely used to treat oily wastewater, but the construction of most of these membranes involves the use of corrosive and even toxic chemicals, and they often exhibit poor chemical durability. Therefore, green and durable super-wetting membranes are urgently required for remediating oily wastewater under harsh conditions. In this study, we report an eggshell membrane (ESM) with super-wettability as a green and durable candidate for efficient oil/water separation under harsh conditions. Specifically, naturally hydrophilic chicken ESMs are directly roughened and drilled using a femtosecond laser, without using any chemicals. Laser-engineered ESMs (LEESMs) possess superhydrophilicity in air and superoleophobicity under water, which renders them capable of separating immiscible oil/water mixtures after they are pre-wetted using water. Results show that the pre-wetted LEESM can cyclically treat various oil/water mixtures with a separation efficiency of >98.6% and water flux of >10000 L·m -2 ·h -1 . Because of the inherent chemical resistance of ESM itself, the LEESMs show excellent durability towards highly corrosive aqueous solutions such as HCl (1 M), NaOH (1 M), and saturated NaCl solution (26.5 wt %). The LEESM retained its underwater superoleophobicity after being immersed in these corrosive solutions for 12 h; therefore, it could be used to separate mixtures of toluene and corrosive solutions efficiently for more than 10 cycles, demonstrating remarkable durability and recyclability in terms of oil/water separation under harsh conditions. Moreover, when the LEESM is pre-wetted or contaminated by oils, it can be easily cleaned by immersing in water, thereby restoring its underwater superoleophobicity and oil/water separation capacity, which prevents it from being fouled during long-term usage. Therefore, this green, anti-corrosive, and self-cleaning LEESM offers insights into the design and fabrication of advanced membranes for practical oily wastewater remediation, as well as the developing and utilization of bio-wastes.

Visual detection of mercury ions and glutathione is of great significance to public health and environmental issues. Herein, we developed a fluorescent sensor (l-Cys/CuNCs@ESM) based on the eggshell membrane (ESM) and red-emitting copper nanoclusters (CuNCs) by the in situ strategy via l-cysteine (l-Cys) as the reducing and protective agent for mercury ions and glutathione sensing visually. The as-prepared fluorescent product had good stability, portability, large Stokes shift (250 nm), and long fluorescence lifetime (7.3 μs). Notably, the l-Cys/CuNCs@ESM exhibited a specific fluorescence quenching response toward Hg2+. Moreover, the interaction between glutathione (GSH) and Hg2+ could subsequently recover the fluorescence effectively. Inspired by this “on-off-on” switch, the l-Cys/CuNCs@ESM was applied as the dual-sensing system for visual detection of mercury ions and glutathione integrating with the portable smartphone. The limit of detection (LOD) of Hg2+ is 1.1 μM for visualization and 0.52 μM for the fluorescence spectrometer. The corresponding LODs of GSH are 2.8 and 0.59 μM, respectively. This platform presents significant sensitivity, specificity, and stability, offering a promising potential for real-time/on-site sensing.

Taking advantages of reticular proteins and reductive groups on the surface, eggshell membrane (ESM) was selected to synthesize MnO 2 nanoparticles from potassium permanganate through a super simple way in which ESM acted as both template and reductant. This process avoided harsh reaction conditions or complicated aftertreatments and thus owned the merits of green synthesis, handy operation, low cost, and easy purification. The ESM-templated MnO 2 nanoparticles (MnO 2 NPs/ESM) were characterized, and the content of nanomaterials on the template was tested. MnO 2 NPs/ESM showed a good capacity for decontamination of tetracycline hydrochloride (TCH). The macroscopical materials can be separated easily by taking the membrane out to stop the degradation instead of centrifugation or filtration. It was studied that 72.27% of TCH (50 mg/L) was decontaminated in 20 min by 0.1920 g/L MnO 2 nanoparticles, and removal efficiency could reach 83.10% after 60 min under buffered condition. The kinetics was studied with or without buffer, and it was concluded that the degradation process followed a pseudo-second-order model. The facile synthesis of materials and effective degradation would facilitate the nano-MnO 2 -based decontamination applications.

Eggshell membrane (ESM), which consists of unique interwoven shell membrane fibers, provides a unique supporting platform for functional nanoparticles in catalysis and sensing. This work reports a novel strategy for fabricating sunlight-driven photothermal conversion composite membranes by loading graphene oxide (GO) and gold nanoparticles (AuNPs) on the three-dimension (3D) network structured eggshell membrane. Surface morphologies and chemical elements were characterized by scanning electron microscopy and X-ray photoelectron spectroscopy. High photothermal conversion under simulated sunlight irradiation, which may be caused by the synergistic effect of GO and AuNPs, was achieved by coating both GO and AuNPs onto ESM. The temperature of ESM modified with AuNPs, and then GO increased from 26.0 °C to 49.0 °C after 10 min of light irradiation. Furthermore, the nanoscaled GO and AuNPs could add benefit to the heating localization of the obtained composite membrane. It is expected this biocompatible ESM modified with GO and AuNPs would have great potential in drug release and photothermal therapy applications.Keywords:eggshell membrane;graphene oxide;gold nanoparticles;sunlight;photothermal effect

Bioremediation is one of efficient methods to solve the issues of water or soil contaminated by metal ions . However, the harvested biowaste is often troublesome to handle owing to the second pollution. Herein, the waste eggshell membrane was used to adsorb Cu 2+ in wastewater, which was then converted into biochar containing copper ions (Cu 2+ -Cu + /Biochar) via a rapid pyrolysis . By integrating the collective advantages of eggshell membrane and Cu 2+ -Cu + , such as superior electrical conductivity, enlarged electrochemically active surface area, unique three-dimensional porous network characteristics, and fast charge transport, the Cu 2+ -Cu + /Biochar system can be used as a self-supporting sensor for detection of nitrite (NO 2 − ). The sensor demonstrated superior electrochemical sensing abilities accompanied by a broad linear range (1–300 μM), ultralow detection limit (0.63 μM), and high sensitivity (30.0 μA·mM −1 ·cm −2 ). In addition, the fabricated electrochemical sensor has excellent stability, good reproducibility, and strong anti-interference performance. More importantly, the sensor has a high recovery rate when it is used to detect nitrite in tap water , mineral water , and sausage, indicating the feasibility of using this sensor in practical applications. This study provides a green and sustainable approach for simultaneous treatment of biomass waste eggshell membrane, remedy of heavy metals, and electrochemical detection of nitrite.

The demerits of the carbonized eggshell membrane (EM), such as high cost, high brittleness, immutable shape and size, greatly limit its application in demanding supercapacitors as free-standing electrode. Herein, the reconstituted EM (REM) with good flexibility and excellent size-customizability is developed, which is due to their fibrous structure and abundant surface polar groups. Ti 3 C 2 nanosheet (a typical MXene) with ultra-high electrical conductivity and good electrochemical activity is then coated on REM surface, and undergoes a low-temperature carbonization (350 °C) to prepare CREM/T. Multi-functions of Ti 3 C 2 are exhibited: (1) constructing a conductive network on REM surface by randomly stacking to yield a high electrical conductivity of 78.1 S cm −1 , (2) being as a protective mold to remain the inherent flexibility and porosity of REM during carbonization, (3) creating nanopores by inducing self-activation, and (4) yielding a large capacitance of 1729 mF cm −2 at 0.5 mA cm −2 and a high rate capability of 82 % after increasing the current density by 50 folds. Furthermore, an all-EM-based supercapacitor is fabricated with REM as the separator and CREM/T as the electrode. It delivers a high energy density of 16.1 μW h cm −2 at 1301 μW cm −2 , and shows stable capacitive behaviors during bending.
