In this work, the effect of the molar ratio of (Ni2+ and Fe3+) on the properties of CdO–NiO–Fe2O3 nanocomposites was investigated. The synthesis of CdO–NiO–Fe2O3 nanocomposites was carried out by self-combustion. XRD, UV–Vis, PL and VSM were used to describe the physical properties of the materials. The results showed significant progress in structural and optical properties supporting antibacterial activity. For all samples, the particle size decreased from 28.96 to 24.95 nm with increasing Ni2+ content and decreasing Fe3+ content, as shown by the XRD pattern, which also shows the crystal structure of cubic CdO, cubic NiO, and cubic γ-Fe2O3 spinel. The Ni2+ and Fe3+ contents in the CdO–NiO–Fe2O3 nanocomposites have also been shown to enhance the ferromagnetic properties. Due to the significant coupling between Fe2O3 and NiO, the coercivity Hc values of the samples increase from 66.4 to 266 Oe. The potential of the nanocomposites for antibacterial activity was investigated against Gram-positive (Staphylococcus aureus) and Gram-negative (Pseudomonas aeruginosa, Escherichia coli, and Moraxella catarrhalis) bacteria. Comparison of P. aeruginosa with E. coli, S. aureus and M. catarrhalis showed that it has a stronger antibacterial activity with a ZOI of 25 mm.

In this study, pure CdO and CdO‐CuO nanopowders with different dopant concentrations are synthesized by the hydrothermal method. Structural properties of the nanopowders are characterized by X‐ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR), morphological properties and elemental analyses are characterized by Field Emission Scanning Electron Microscopy (FESEM), optical properties are characterized by UV–vis spectroscopy, and electrical properties are characterized by the current–voltage technique. XRD data show that nanopowders are polycrystalline and crystallinity decreases with the doping concentration. In the analysis of FESEM images, it can be concluded that the morphology of the particles is shaped as needle‐like, spherical‐like, and randomly oriented nanorods forms from the cube form. Also, by joining those nanorods, spherical‐like microstructures occur, and while the dopant concentration increases, echinus‐like forms are obtained. The energy bandgap of the nanopowders decreases with an increased dopant concentration of CuO. It is observed that the dopant concentration of CuO also changes the electrical properties.

Microbial mediated synthesis of metallic nanoparticles constitutes as effective and promising approach for the development of antibacterial materials in the field of bioengineering and biomedicine. We prepared Cadmium oxide nanoaprticles (CdO NPs) utilizing Penicillium oxalicum, and cadmium acetate solution via coprecipitate method. The elemental composition and morphology of these synthesized CdO NPs were examined through X-ray diffraction (XRD), UV-Vis absorption spectroscopy, Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), and Energy dispersive spectroscopy (EDS). Furthermore, we evaluated the bactericidal potential of prepared CdO NPs using Escherichia coli (E.coli), Staphylococcus aureus (S.aureus), Bacillus cereus (B.cereus), and Pseudomonas aeruginosa (P. aeruginosa). Dimethyl sulfoxide was used as negative control while erythromycin was used as positive control. The XRD spectrum revealed cubic crystalline nanoparticles with 22.94 nm size and UV showed absorbance peak at 297 nm with 2.5 eV band gap energy. FTIR depicted O─H and carboxylic groups along with CdO stretching vibration. EDS showed the presence of organic compounds on Cd and O over NPs surface. SEM results revealed the spherical shape of the CdO NPs. The synthesized NPs exhibited highly potent bactericidal activity against selected strains and demonstrated less optical density of 0.086 after 24 hr. Owing to the significant antibacterial activity of CdO NPs, the broad application prospects of these nanoparticles CdO NPs in extensive biomedical applications is indicated.
