Assessment of catalytic and antibacterial activity of biocompatible agar supported ZnS/CuFe2O4 magnetic nanotubes

Abstract

The tubular magnetic agar supported ZnS/CuFe2O4 nanocomposite was fabricated via a simple procedure. Next, various properties of this nanocomposite were studied by employing multiple characterization techniques including FT-IR, EDX, SEM, TEM,VSM, XRD, and TGA. Then, the catalytic and antibacterial applications were evaluated for the fabricated nanocomposite. Based on the experimental result, the nanocomposite showed excellent catalytic activity to promote the multicomponent reaction between ethyl acetoacetate, hydrazine hydrate, aromatic aldehydes, and malononitrile to synthesize a variety of dihydropyrano[2,3-c]pyrazole derivatives with high yields (89–95%) in acceptable reaction times (20–40 min) under mild reaction conditions. It can be efficiently recycled and re-work in six consequent runs without notable reduction in catalytic productiveness. Furthermore, its antibacterial activity was assessed against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) bacteria by the agar diffusion and plate-count methods. These results indicate that the width of the inhibition zone around the S. aureus (G+ bacterium) is more than that of E. coli (G− bacterium). Moreover, the agar supported ZnS/CuFe2O4 nanocomposite exhibited strong prevention of the bacterial colonies’ growth.

Hierarchical Fe2O3 hexagonal nanoplatelets anchored on SnO2 nanofibers for high-performance asymmetric supercapacitor device

“…Tubular nanomaterials have received significant study attention in recent years due to their hollow shape, which provides a number of unique features that should be beneficial in a variety of applications such as information storage medium 14 , catalysts 15 , electronics 16 , gas sensors 17 , and medicine 18 . Therefore, many methods have been reported for preparing tubular magnetic nanomaterials, including template-assisted electrodeposition 19 , co-precipitation 20 , sol-gel 21 and solvothermal 22 methods. Nonetheless, these methods are frequently hampered by time-consuming procedures and special situations.…”

Antibacterial Properties of PMMA Functionalized with CuFe2O4/Cu2O/CuO Nanoparticles

“…The S. aureus cell wall has a single thick membrane of peptidoglycan. Therefore, E. coli is more impressible for penetrating antibacterial agents [53]. The antibacterial effect of the CuFe 2 O 4 /Cu 2 O/CuO/PMMA composite may be described using three mechanisms:…”
