Anti-inflammatory and Antimicrobial Potential of Cissus quadrangularis-Assisted Copper Oxide Nanoparticles

Recently, nontoxic origin-mediated synthesis of copper oxide nanoparticles acquires further recognition because of the key role of bioapplications. The plant Cissus quadrangularis is one most prominent herbs used in the treatment of diabetes, asthma, tissue regeneration, etc. In this study, we tested the process of copper oxide nanoparticle synthesis and their role in many functions from Cissus quadrangularis. The synthesis of copper oxide nanoparticles uses plant extract and characterization by X-ray diffraction, thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FT-IR), atomic force microscope (AFM), and scanning electron microscope (SEM). The synthesized nanoparticles were analyzed for their biomedical applications such as antibacterial, antifungal, antioxidant, antidiabetic, and anti-inflammatory activity and antiproteinase action. The results show that the C. quadrangularis plant-mediated nanoparticles may be used in many biomedical applications related to arthritis, diabetes, and the production of various antimicrobial products in the future.

In material science, green method for synthesis of nanomaterials is feasible, cheaper and eco-friendly protocol. To accomplish this phenomenon, present study was aimed to synthesize Copper oxide nanoparticles using leaf extract of Aloevera with two different precursors CuCl2.2H2O (Cupric chloride) and CuSo4.5H2O (Cupric sulfate). The extraction of Aloevera is employed as reducing and stabilizing agent for this synthesis.Copper oxide Nanoparticles is effective use of biomedical application due to their antibacterial function. The synthesized Copper oxide nanoparticles were characterized by X-Ray Diffraction Spectroscopy (XRD), Energy Dispersive Spectroscopy (EDX), FourierTransform Infrared Spectroscopy (FT- IR) and Scanning Electron Microscope(SEM). XRD studies reveal the crystallographic nature of Copper oxide nanoparticles. Furthermore the Copper oxide nanoparticles have good Antibacterial activity against both gram negative (E.Coli, Klebsiella pneumonia) and gram positive (Bacillus cereus, Staphylococcus aureus)bacteria.

Nickel-substituted copper oxide nanoparticles at various concentrations were synthesized by the microwave irradiation technique. The consequence of nickel doping on crystal structure, optical properties, and magnetic properties was examined by means of X-ray diffractometer, ultraviolet-visible spectrometer, Fourier transform infrared (FT-IR) spectrometer, transmission electron microscope, and vibrating sample magnetometer (VSM). X-ray diffraction analysis shows that the samples are monoclinic and their crystallite size varies from 25[Formula: see text]nm to 42[Formula: see text]nm, and lattice constant significantly increases with nickel concentration. Additional increase of nickel content (7%) decreases the lattice constant. TEM micrograph witnessed that the prepared nanoparticles were sphere-shaped and the particle distribution is in the range between 20 and 40[Formula: see text]nm. Bandgap measurement reveals that both undoped and nickel-doped copper oxides are direct bandgap semiconductor materials with bandgaps of 3.21 and 3.10[Formula: see text]eV, respectively, FT-IR spectra of the synthesized samples confirmed the nickel doping. VSM studies confirmed the ferromagnetic behavior of the synthesized samples at room temperature. The results revealed that the nickel-doped copper oxide nanoparticles synthesized via the microwave irradiation method exhibit better magnetic properties than the undoped copper oxide.

The development of green technology is creating great interest for researchers towards low-cost and environmentally friendly methods for the synthesis of nanoparticles. Copper oxide nanoparticles (CuO-NPs) attracted many researchers due to their electric, catalytic, optical, textile, photonic, monofluid, and pharmacological activities that depend on the shape and size of the nanoparticles. This investigation aims copper oxide nanoparticles synthesis using Aerva javanica plant leaf extract. Characterization of copper oxide nanoparticles synthesized by green route was performed by three different techniques: X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR) Spectroscopy, and Scanning Electron Microscopy (SEM). X-ray diffraction (XRD) reveals the crystalline morphology of CuO-NPs and the average crystal size obtained is 15 nm. SEM images showed the spherical nature of the particles and size is lying in the 15–23 nm range. FTIR analysis confirms the functional groups of active components present in the extract which are responsible for reducing and capping agents for the synthesis of CuO-NPs. The synthesized CuO-NPs were studied for their antimicrobial potential against different bacterial as well as fungal pathogens. The results indicated that CuO-NPs show maximum antimicrobial activities against all the selected bacterial and fungal pathogens. Antimicrobial activities of copper oxide nanoparticles were compared with standard drugs Norfloxacin and amphotericin B antibiotics. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of copper oxide nanoparticles were 128 μg/mL against all selected bacterial pathogens. MIC of fungus and minimum fungicidal concentration (MFC) of CuO-NPs were 160 μg/mL. Thus, CuO-NPs can be utilized as a broad-spectrum antimicrobial agent. The cytotoxic activity of the synthesized CuO-NPs suggested that toxicity was negligible at concentrations below 60 μg/mL.
