“…Figure 6 illustrates the M-H loop of the rGO/Fe 3 O 4 /CS (15%) nanocomposite under a maximum induced magnetic field of ± 30 kOe at room temperature. The prepared nanocomposite was superparamagnetic with a saturation magnetization (MS) of 5.27 emu/g, attributed to Fe 3 O 4 NPs in the composition 8 , 20 . However, it should be noted that the obtained MS value was low compared to that of pure Fe 3 O 4 NPs according to the previous reports 28 .…”

“…The binding structure of AO to adherent cells caused by the in vitro biofilm formation of GO, CS, Fe 3 O 4 NPs, rGO/Fe 3 O 4 , and rGO/Fe 3 O 4 /CS nanocomposites was observed using confocal laser scanning microscopy (CLSM). The bacteria Streptococcus pneumoniae ( S. pneumoniae), Pseudomonas aeruginosa ( P. aeruginosa), and fungus Candida albicans (C. albicans), have been studied in detail concerning their ability to form biofilms 8 . The Fe 3 O 4 NPs with a minimum inhibitory concentration (MIC) of 50 μg had a minimal effect compared to the control on the biofilm structure and the proportion of the live bacteria in the biofilm after a 12 h incubation.…”

“…The peripheral carboxylic group (–COO) can stabilize the colloidal system and create a pH-responsive negative charge surface. However, the basal plane having hydroxyl (–OH) and the epoxide (–O − ) groups results in the weak chemical interaction, such as H-bonding, or chemical interaction causing the transpire on the surface 8 – 11 . Even the entire areas of GO can be used for drug loading and non-covalent functionalization because of the possible π–π interactions on the basal plane.…”

A hybrid and straightforward nanosystem that can be used simultaneously for cancer-targeted fluorescence imaging and targeted drug delivery in vitro was reported in this study. A chitosan (CS) polymer coated with reduced graphene oxide (rGO) and implanted with Fe3O4 nanoparticles was fabricated. The fundamental physicochemical properties were confirmed via FT-IR, XRD, FE-SEM, HR-TEM, XPS, and VSM analysis. The in vivo toxicity study in zebrafish showed that the nanocomposite was not toxic. The in vitro drug loading amount was 0.448 mg/mL−1 for doxorubicin, an anticancer therapeutic, in the rGO/Fe3O4/CS nanocomposite. Furthermore, the pH-regulated release was observed using folic acid. Cellular uptake and multimodal imaging revealed the benefit of the folic acid-conjugated nanocomposite as a drug carrier, which remarkably improves the doxorubicin accumulation inside the cancer cells over-express folate receptors. The rGO/Fe3O4/CS nanocomposite showed enhanced antibiofilm and antioxidant properties compared to other materials. This study's outcomes support the use of the nanocomposite in targeted chemotherapy and the potential applications in the polymer, cosmetic, biomedical, and food industries.

“…Most recently, plant extracts have also been used as both a reducing and a gelling agent for the synthesis of mixed metal oxides. The plant extract plays a role as a fuel, and also has an organizing action, apprehending the metal ions present in the amylose helix of the plant extract, and obstructing the separation of metal oxides synthesized through the green method, which has been reported previously [14,15,16,17,18,19]. …”

Microwave-Assisted Synthesis of Nickel Oxide Nanoparticles Using Coriandrum sativum Leaf Extract and Their Structural-Magnetic Catalytic Properties

In this paper, using Coriandrum sativum L., a leaf-extracted, assisted microwave method (MM) was used to synthesize nickel oxide formation. We synthesized nickel oxide nanoparticles (NiO) with a crystal size in the range of 15–16 nm by a Coriandrum sativum leaf-assisted microwave method (LAMM). The synthesized materials show that an X-ray diffraction (XRD) study confirmed the formation of a single phase structure exhibiting a crystallite size in the range of 15–16 nm using Scherrer’s method. The nickel oxide prepared by the MM had a surface area of 60.35 m2/g, pore volume of 0.9427 cm3/g and an average pore diameter of 13.27 Å. Surface morphology was analyzed by the scanning electron microscope (SEM), X-ray photoelectron spectroscope, Brunauer-Emmett-Teller (BET) analysis, and the vibrating sample magnetometer (VSM). Catalytic activity (CA) tended toward the oxidation of styrene to benzaldehyde. The inexpensive catalyst tested is likely effective as a catalyst due to synergistic interactions between metal oxides with high dispersion. In comparison with other findings, LAMM is easy and eco-friendly. The current study obtained nanocrystalline NiO that was suitable for potential applications in catalysis. The synthesized NiO could potentially be used in therapeutic field due to their competent antibacterial activity.

“…Nonetheless, that the catalyst surface gets regenerated by the action of the oxidant with the catalyst, in which indications to the desorption of the product particles interact into catalytic reaction, thus [14,15] preferring additional oxidation (Scheme 1). The oxidation of benzyl alcohol to benzaldehyde on cobalt oxide catalysts is proposed for mechanism and the several authors have investigated for catalytic properties were reported [16][17][18][19].…”

In this article, Co 3 O 4 nanoparticles were synthesize by the uncomplicated microwave treatment. The Co 3 O 4 nanoparticles have characterized by transmission electron microscopy, Brunauer-Emmett-Teller specific surface area dimension and the X-ray diffraction.
