In this study the waste fish scales (FS) were dissolved in 1-butyl-3-methylimidazolium acetate ionic liquid to obtain a valuable product of hydroxyapatite (HAp). The HAp was obtained in the yield of 32 ± 2%. The obtained HAp was characterized using Fourier Transform Infrared Spectroscopy (FTIR), Powder X-rays Diffraction (PXRD), Thermal Gravimetric Analysis (TGA), Field Emission Scanning Microscopy (FE-SEM), Energy Dispersive X-rays spectroscopy (EDX), and Brunauer–Emmett–Teller (BET). The results of FTIR and XRD showed the characteristic peaks of the HAp. The thermal degradation temperature of the extracted HAp was relatively high. Furthermore, low weight loss was measured which confirmed the removal of organic part of FS during ionic liquid treatment. The FE-SEM result showed the particles with different morphologies and EDX analysis showed a Ca/P ratio of 1.60 for the extracted HAp. The biocompatibility of the extracted HAp was assessed through MTT cell viability assay using known Human Embryonic Kidney 293 cells (HEK cells) and epidermoid carcinoma cells (A431 cells).

Fish scales, considered as low-value by-products, contain peptides and hydroxyapatite that can be applied to produce peptide chelated calcium directly. This study developed a sustainable and one-pot fabrication method for the peptide-chelated calcium from fish scale hydrolysates (FSP-Ca). During pepsin hydrolysis, the releases of peptides (FSP), calcium, and phosphate from fish scales occurred simultaneously, and the chelation was also effectively performed. After a 6-h hydrolysis, the yield of FSP was 46.18%, and the dissolution rate of calcium was 49.53%. Under the optimal conditions (pH 7, chelation time of 25 min, and chelation temperature of 48 °C), a high chelation rate of 86.16% was obtained, with a calcium content of 81.8 mg/g. The results of UV absorption, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM) confirmed the successful chelation between FSP and calcium derived from fish scales. The –NH 2 , –COO – , N–H, C=O, C–H, and –OH groups in FSP participated in the formation of FSP-Ca. Graphical Abstract

This study presents the development of a biodegradable composite scaffold designed to address the limitations associated with conventional bone repair materials. 3D-printing filaments were developed using fish scale powder (FSP) or fish scale-derived hydroxyapatite (HAP), polylactic acid (PLA), and polycaprolactone (PCL), with a focus on the optimal effect of 5 wt% HAP on the mechanical properties of PLA. Composite scaffolds were further prepared by integrating 3D-printed grid scaffolds with chitosan/gelatin composite hydrogels through vacuum freeze-drying. The properties of the composite scaffolds were evaluated through mechanical property tests, thermal analysis (including DSC and TGA), absorption rate assessments (conducted via immersion experiments in various solutions), and surface morphology analyses (utilizing SEM and EDS). The results show that the addition of HAP significantly improves the mechanical properties of 3D-printed filaments. The high absorption rate exhibited by the HAP/PLA composite scaffold suggests improved biocompatibility and its potential for in vivo tissue fluid absorption. The HAP/PLA composite scaffold showed visible surface mineralization and degradation after 10 days of immersion in simulated body fluid (SBF), highlighting its potential for bone repair and regeneration.

Extracellular matrix (ECM) with various micro/nano features is an important chemical and physical clue to control cell behaviors. Fish scale surface has rich structures and similar components to ECM, but there are no reports on directly using the natural surface of fish scales to guide cell behavior. Herein, natural interface of waste fish scales can be directly, simply, green, and low-costly used to regulate cell behavior. A series of characterization showed that the natural surface of fish scales is rich in micro/nano structures (groove, short ridge, fibers), contain collagen and hydroxyapatite, has suitable wettability and no cytotoxicity. These natural structures on waste fish scales have adjustable cell guidance abilities, which are consistent with the anisotropy levels of these structures (ordered fibers > grooves > damaged fibers > short ridges). Moreover, cell contact interaction with micro/nano topographies on the fish scale surface is dynamically adjustable with growth time, and also increased the chemoresistance of cancer cells to drug (irinotecan and cisplatin). Due to its advantages of wide material sources, waste recycling, patterning-free, and pretreatment-free, directly using biowastes (fish scales) not only provides a new opportunity for the development of in vitro anisotropic culture platform, but also helps to deepen the understanding and application of natural materials.

Inspired by fish scales, superhydrophilic and underwater superoleophobic alumina membranes were fabricated in this study. Dopamine deposited on the surface of alumina membranes through immersion over time, and then crosslinking reaction occurred with polyethyleneimine (PEI), which was confirmed by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. It induced the modified layer coated on the membrane surface. Values of water contact angle of the modified alumina membranes were ~ 0° in air. Values of underwater oil contact angle reached 155°, which indicated it was superhydrophilic and underwater superoleophobic. More particles engendered with the increase in the reaction time with PEI, which induced the decrease in the pore sizes and permeation flux. All values of oil rejection were higher than 98.5%. No obvious deterioration of permeation flux could be found. The rejection hardly suffered a sharp decline over 800 min. It indicates that the modified layer can firmly stick to the alumina membranes. Therefore, the as-prepared alumina membrane is promising for practical oil/water separation.

This paper explores the structural and functional properties of collagen from tilapia scales pretreated by heat-assisted ionic liquids (ILs). Results show that the solubility of collagen was significantly influenced by the type and concentration of ILs. With the increase of IL concentration, a remarkable decrease in solubility of collagen was seen. Fluorescence spectra show that heat and IL pretreatments induced the exposure of chromophores. Changes in sodium dodecyl sulfate–polyacrylamide gel electrophoresis indicated that subunits of collagen regenerated from most of the IL solvent systems were not destroyed. The functional properties of regenerated collagen were evaluated by gel strength, viscosity, water-binding capacity, and emulsifying capacity. Results show that all heat-assisted ILs pretreatments improved the gel strength and viscosity, and the highest gel strength and viscosity were both obtained in the collagen pretreated by heat-assisted [EMIM]Cl. Heat-assisted [BMIM]BF 4 pretreatment exhibited the lowest water-binding capacity. Heat-assisted [BDMIM]Cl pretreatment indicated superior effect on improving emulsifying capacity than other pretreatments due to its ability to break most of the hydrogen bonds in collagen molecules, resulting in the formation of new re-aggregates with higher solubility and more hydrophobic groups.

Pollution from oily waste water is a serious environmental problem worldwide, causing serious damage to the environment and human health. At the same time, emulsifiers also cause great difficulties in wastewater treatment. Although efforts have been made to develop many high performance emulsion separation membranes, it is difficult to have the ability to resist crude oil pollution in practical applications. The construction of superoleophobic micro/nano-scale lamellar structured membranes with the potential to efficiently separate oil/water emulsions was inspired by the oil-resistant properties of fish scales and the unique adhesion of mussels. Tin dioxide, polydopamine and hydrophilic barium sulphate have been modified on the surface of stainless steel mesh by in-situ hydrothermal and dip coating. The superhydrophilic stainless steel mesh was successfully prepared by using the adhesion of polydopamine. Using the excellent underwater hydration ability of tin dioxide and the hydroxyl group-rich hydrophilic barium sulfate, the modified membrane showed excellent resistance to crude oil pollution. The superhydrophilic membrane can continuously separate different types of oil-in-water emulsions with high separation efficiency (99.9 %) and excellent separation flux (900 L m −2 h −1 ), with no decrease in efficiency and flux after 10 emulsion separation cycles. In addition, the superhydrophilic membrane has excellent durability and stability, remaining super-oleophobic underwater to sand shock, sandpaper abrasion, high saline corrosion and UV ageing. The prepared stainless steel membrane not only provides a novel anti-fouling strategy, but its excellent stability also provides some new inspiration for the treatment of oil and water pollution in the future.

Developing safe and efficient diclofenac sodium (DS) removal technology has become a critical issue. This study synthesized the fish-scale biochar by co-pyrolysis of fish scale and phosphoric acid (H 3 PO 4 ). In addition to increasing the specific surface area and pore volume of fish-scale biochar, H 3 PO 4 assisted in the formation of Graphitic N and sp 2 C, as well as reacting with C═O groups to form a significant number of phosphorus-containing groups. All these functional groups could act as major active sites for DS adsorption. Adsorption data could well fit pseudo-second-order and Langmuir models. The maximum adsorption capacity of FSB 600-15 for DS was 967.1 mg g −1 , which was much better than that reported in the literature. Under the synergistic effect of various mechanisms (pore-filling effect, electrostatic attraction, H-bonding, π-π, and n-π electron donor-acceptor interactions), the DS ultra-efficient adsorption on FSB 600-15 was realized. Meanwhile, the DS adsorption by FSB 600-15 was an endothermic, spontaneous, and entropy-increasing process. Furthermore, the DS adsorption capacity was more than 426.5 mg g −1 in the actual water, which was sufficient for practical applications.

A multifunctional and environmentally friendly composite film was developed by incorporating pomelo peel-derived carbon dots (PCDs) into a fish scale gelatin (FSG)/alginate dialdehyde (ADA) biopolymer matrix. ADA was used to reinforce the physicomechanical properties of the FSG film via Schiff base crosslinking. PCDs with strong antioxidant and antimicrobial activities were synthesized via a hydrothermal method . The effect of various PCDs content on the surface morphological, physicochemical, and functional characteristics of the composite films was investigated. The results showed that the introduction of PCDs into the FSG/ADA matrix effectively reinforced the mechanical performance, enhanced the water vapor and water resistance, increased UV-light blocking, conferred fluorescence properties, and improved the thermal properties of the composite films. Under 3 wt% PCDs content, the FSG/ADA/PCDs-3 % composite film not only presented significant antioxidant capacity with a radical scavenging rate of 91.71 % for DPPH and approximately 100 % for ABTS , but also exhibited excellent antimicrobial ability against bacteria and fungi. Results of a preservation experiment showed that the prepared FSG/ADA/PCDs-3 % film preserved the physiological qualities of strawberries post-harvest and extended their shelf-life to 7 days at room temperature. Overall, the fabricated FSG/ADA/PCDs composite films are promising for use in eco-friendly active food packaging.

Summary The combined effects of gelatin extraction methods and protease types on the functional properties of tilapia scale gelatin hydrolysates (TSGH) were investigated. The tilapia scale gelatin (TSG) was extracted after acid/base pretreatments, respectively, and then hydrolysed with different proteases to produce TSGHs. The degree of hydrolysis and the content of trichloroacetic acid soluble peptide were increased with hydrolysis time, while the content of β-sheet was decreased significantly with the hydrolysis time ( P < 0.05). The emulsification stability of acid protease hydrolysate (APH) was higher than that of neutral protease hydrolysate (NPH) and alkaline protease hydrolysate (ALPH). All samples showed good resistance to oxidation: DPPH (20%–64.66%), ABTS (29.08%–63.04%), and iron reducing power (0.017–0.499). The hydrolysates obtained from the base-pretreated TSG showed higher antioxidant properties than acid-pretreated TSG. The antioxidants of different protease hydrolysates are ranked by ALPH > NPH > APH. In conclusion, gelatin extraction methods and its hydrolysis conditions had influences on the functional properties of TSGH, and the study of the processing of marine biological wastes is of great significance in realising their high-value utilisation and reducing the burden on the environment.

Membrane fouling is still an inevitable main challenge to nanofiltration (NF) process, which leads to a decline in membrane performance. Inspired by fish scales, a facile method was performed to develop composite NF membranes with highly stable antifouling property based on hydrophilic roughness. γ-(2,3-glycidyloxy) trimethoxysilane (KH560) grafted onto PEI molecules during interfacial polymerization on hydrophilic microporous PTFE support. Finally, tetraethyl orthosilicate (TEOS) reacted with KH560 molecules. Results of fourier transform infrared (FTIR) spectra, FESEM and contact angle measurements indicated that micro/nano hydrophilic SiO 2 spheres engendered on the membrane surface. Evaluation of membrane antifouling property showed that flux recovery ratio (FRR) of BSA, HA, SDS and Oil/water mixture for the as-prepared NF membranes were 96.0%, 95.8%, 96.8% and 95.0%, respectively. No obvious permeate flux decline and rejection fluctuation could be observed in filtration experiment of MgSO 4 aqueous solution on long-term run (100 h). It indicated highly stable antifouling property, which may be due to hydrophilic microscale/nanoscale SiO 2 spheres grafted onto the skin layer of the as-prepared NF membranes through chemical linkage. It is expected that these findings could provide more insight for fabrication and simultaneous modification of NF membranes.

The increasing utilization of nuclear energy and radiation medicine has urged flexible neutron shielding materials for personal protection. However, it was a challenge to manufacture neutron shielding materials with good flexibility and efficient neutron shielding performance. Herein, a new type of hybrid filler named Gd@MXene nanoflakes were successfully synthesized via one step-hydrothermal reaction and used for efficient neutron shielding, which was composed of two-dimensional (2D) Ti3C2Tx-MXene nanoflakes and zero-dimensional Gd nanoparticles (NPs). Inspired by fish scales, the spin coating method was employed to manufacture the film composed of polyvinyl alcohol (PVA) and Gd@MXene, which aligned random Gd@MXene into oriented 2D fish scale-like barrier walls. The 2D fish scale-like Gd@MXene barrier walls scattered the neutron rays multiple times between the nanoflakes, thereby improving the neutron absorption efficiency of Gd atoms. The film showed excellent neutron shielding performance and thermal conductivity; the neutron shielding rate of 20-Gd@MXene/PVA with a thickness of 62 μm was 3.36 times higher than that of pure PVA. The thermal conductivity of Gd@MXene/PVA was nearly 10 times higher than that of pure PVA. This work introduced a novel film for neutron radiation shielding and had potential applications in personal wearable protective equipment.
