“…In the diffusion method, 100 µL bacterial suspension (S. aureus, P. aeruginosa, and E. coli) was evenly coated on the agar LB solid medium with 9 mm holes [41]. Briefly, 0.1 g F/C-Ag was then added to the well and incubated at 37 • C for 24 h; bacterial growth around the material was observed [42].…”

Microbial contamination has caused various diseases via pathogenic bacteria, endangering people’s lives every day. Recently, increasing attention has been paid to the exploration of new and effective antibacterial materials. In this paper, we attempted to synthesize a fish scale charcoal nanosilver antibacterial composite using waste fish scale as a carbon substrate. X-ray diffraction, Fourier-transform infrared spectroscopy, thermogravimetry-differential scanning calorimetry, and scanning electron microscopy showed that the structure of the nanosilver fish scale material formed and the nanosilver particles formed account for 72.1% of the silver element. Its antibacterial ability against Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa was examined using the plate counting method and inhibition zones; the maximum inhibition zone was 32 mm. The antibacterial rate could reach >99.9%, indicating that this prepared material had excellent antibacterial activity. After 20 batches of bacteriostasis, the bacteriostasis rate was more than 90%, indicating that the fish scale/silver composite had sustained antibacterial ability and excellent antibacterial reusability. Finally, potential antibacterial mechanism was proposed. Overall, the fish scale/silver composite has a good application prospect and a wide range of applications in the handling of microbial pollution in the future.

Bone grafts or prosthetic implant designing for clinical application is challenging due to the complexity of integrated physiological processes. The revolutionary advances of nanotechnology in the biomaterial field expedite and endorse the current unresolved complexity in functional bone graft and implant design. Rare earth (RE) materials are emerging biomaterials in tissue engineering due to their unique biocompatibility, fluorescence upconversion, antimicrobial, antioxidants, and anti‐inflammatory properties. Researchers have developed various RE smart nano‐biomaterials for bone tissue engineering and implantology applications in the past two decades. Furthermore, researchers have explored the molecular mechanisms of RE material‐mediated tissue regeneration. Recent advances in biomedical applications of micro or nano‐scale RE materials have provided a foundation for developing novel, cost‐effective bone tissue engineering strategies. This review attempted to provide an overview of RE nanomaterials' technological innovations in bone tissue engineering and implantology and summarized the osteogenic, angiogenic, immunomodulatory, antioxidant, in vivo bone tissue imaging, and antimicrobial properties of various RE nanomaterials, as well as the molecular mechanisms involved in these biological events. Further, we extend to discuss the challenges and prospects of RE smart nano‐biomaterials in the field of bone tissue engineering and implantology.

“…Semiconductor nanomaterials like TiO2, ZnS, ZnO are suitable candidates for photocatalysis, however ZnO is the most commonly used owing to its low cost, inertness to chemicals, nontoxicity and resistance against corrosion [15][16][17][18][19]. In practical applications however, ZnO has narrow range of spectral response especially under UV irradiation (λ < 380 nm) which contributes to only 6-8% of solar energy whereas visible light contributes 46%.…”

In the present work, ZnO nanoparticles were doped with varying concentration of Lanthanum (La), Cerium (Ce) and Dysprosium (Dy) using a simple and cost effective co-precipitation approach at low temperatures. The resulting powders were calcined at 500 °C for 1 hour using a muffle furnace, to produce La, Ce, Dy co-doped ZnO nanoparticles with varying stoichiometry viz. Zn0.97La0.01Ce0.01Dy0.01O, Zn0.94La0.02Ce0.02Dy0.02O, Zn0.91La0.03Ce0.03Dy0.03O, Zn0.88La0.04Ce0.04 Dy0.04O and Zn0.85La0.05Ce0.05Dy0.05O. This is a simple approach for doping and doesn’t require and complex equipment, harmful chemical or sophisticated machinery. The synthesized powders were characterized using X-Ray diffraction (XRD) and Scanning electron microscopy (SEM) for studying the structure, purity, and grain morphology. The average particle size was calculated using XRD and was found to be 35 nm, it also indicated a hexagonal wurtizite structure with no secondary peaks. A change in morphology from nanorods to nanoflowers was observed as the concentration of dopants increased. Photoluminescence (PL) spectra indicated a red shift in the absorption edge towards the visible region of solar spectrum and this was further confirmed by Diffuse Reflectance Spectra (DRS). The photocatalytic properties of undoped and La, Ce, Dy co-doped ZnO nanoparticles were observed by examining the photodegradation of Rhodamine B dye under UV irradiation. Elimination of dye color indicated the total degradation of organic molecule. The results revealed that ZnO photocatalyst with La, Ce, Dy co-doping concentration Zn0.85La0.05Ce0.05Dy0.05O exhibited the best photocatalytic performance (95%) as compared to undoped ZnO. The improved photocatalytic performance can be attributed to the increased surface oxygen vacancies and adsorption capacity. Delay in recombination of charge carriers due to creation trap states in the bandgap of ZnO further improves the photocatalytic performance of doped samples.
