“…The polymer brushes in the tentacle‐like structure of the PEI extend away from the support surface, allowing catalase molecules to bind to the multiple layers of the tentacle polymer and boost catalase immobilization efficiency 62 . According to previous studies, copper presents biological compatibility, stability, non‐immunogenicity, conjugation potential, catalyzing property, renewability, antimicrobial efficiency, and so on 72,73 . In addition, the main reason why binding via Cu 2+ ions is preferred in this study is that it provides sufficient binding strength for immobilization while effectively preventing the inactivation and denaturation of catalase 14 …”

A common industrial byproduct known as hydrogen peroxide, which is an essential intermediate, is associated with oxidative damage to brain cells and a number of neurodegenerative disorders. Although catalases are enzymes capable of decomposing hydrogen peroxide into water and oxygen, the low stability of free enzymes limits their industrial use. In the current study, poly(ε‐caprolactone)/polyethyleneimine nanofibers were fabricated using the electrospinning process and catalase was subsequently immobilized via coordination of Cu2+ ions. The characterization of the catalase‐immobilized nanofibers and their catalytic activity for hydrogen peroxide decomposition was evaluated by comparing the free catalase. The studies conducted in the pH range of 5.0–8.5 revealed that the catalase‐immobilized nanofibers had their highest levels of enzyme activity at pH 7.0. When compared to free catalase, it was shown that the thermal stability and storage stability of catalase‐immobilized nanofibers were significantly improved. Catalase‐immobilized nanofibers showed significant reusability, where activity was maintained by around 60% after five repeating cycles. The findings showed that catalase‐immobilized PCL/PEI‐Cu2+ nanofibers had a high potential for various industrial applications as a substitute for the existing techniques.

“…However, these methods can promote or cause performance reduction in the cells, even malfunction or death of such living cells. IONPs synthesized by biological methods can yield narrow size distribution properties, which are essential for application in MRI contrast agents with uniform-sized NPs for better imaging quality [ 207 ]. To allow IONPs to suit some specific applications, the biological synthesis method can be fine-tuned to control the size, shape, and excellent multifunctional properties.…”

The significance of green synthesized nanomaterials with a uniform shape, reduced sizes, superior mechanical capabilities, phase microstructure, magnetic behavior, and superior performance cannot be overemphasized. Iron oxide nanoparticles (IONPs) are found within the size range of 1–100 nm in nanomaterials and have a diverse range of applications in fields such as biomedicine, wastewater purification, and environmental remediation. Nevertheless, the understanding of their fundamental material composition, chemical reactions, toxicological properties, and research methodologies is constrained and extensively elucidated during their practical implementation. The importance of producing IONPs using advanced nanofabrication techniques that exhibit strong potential for disease therapy, microbial pathogen control, and elimination of cancer cells is underscored by the adoption of the green synthesis approach. These IONPs can serve as viable alternatives for soil remediation and the elimination of environmental contaminants. Therefore, this paper presents a comprehensive analysis of the research conducted on different types of IONPs and IONP composite-based materials. It examines the synthesis methods and characterization techniques employed in these studies and also addresses the obstacles encountered in prior investigations with comparable objectives. A green engineering strategy was proposed for the synthesis, characterization, and application of IONPs and their composites with reduced environmental impact. Additionally, the influence of their phase structure, magnetic properties, biocompatibility, toxicity, milling time, nanoparticle size, and shape was also discussed. The study proposes the use of biological and physicochemical methods as a more viable alternative nanofabrication strategy that can mitigate the limitations imposed by the conventional methods of IONP synthesis.

“…There are various chemical, physical or biological methods to prepare NCs containing copper or copper oxide NPs having antimicrobial activity [ 16 ]. Biological synthesis of metal/metal oxide NPs can be carried out by various extracts of plants, bacteria, fungi, and lichens with desirable biocompatibility property compared to physical or chemical methods [ 17 , 18 ]. In the case of plant extracts, several parts including fruits, leaves, stems, roots, and seeds having primary and secondary metabolites can participate in the preparation of metal/metal oxide NPs [ 19 – 21 ].…”

Introduction Nanocomposites based on copper, iron, and carbon materials are novel nanomaterials with both antibacterial and biocompatibility properties considerable to fight against multidrug-resistant bacteria. Methods In this study, phytogenic carbon/FeSO4/Cu/CuO nanocomposites modified by three antibiotics including tetracycline, amoxicillin, and penicillin were employed to hinder antibiotic resistant bacteria of Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa. Interaction of albumin and hemoglobin as major blood proteins with these nanocomposites were evaluated by SEM, FTIR, and AFM techniques. As in silico study, molecular docking properties of staphylococcal enterotoxin toxin A and B with (Z)-α-Bisabolene epoxide, (E)-Nerolidol, α-Cyperone, daphnauranol C, nootkatin, and nootkatone as major secondary metabolites of Daphne mucronata were obtained by AutoDock Vina program. Results Physicochemical characterization of nanocomposites showed (Zeta potential (− 5.09 mV), Z-average (460.2 d.nm), polydispersity index (0.293), and size range of 44.58 ± 6.78 nm). Results of both in vitro and in silico surveys disclosed significant antibacterial activity of antibiotic functionalized carbon/FeSO4/Cu/CuO nanocomposites compared to antibiotics alone towards Gram-negative and Gram-positive bacteria. Conclusion Synergistic activity of bio-fabricated carbon/FeSO4/Cu/CuO nanocomposites with antibiotics may be affected by main parameters of concentration and ratio of antibacterial agents, physicochemical properties of nanocomposites, bacterial type (Gram-negative or Gram-positive), antibacterial mechanisms, and chemical structure of antibiotics.
