Synthesis of CoFe₂O₄/BiOI nanocomposite; Its application as an antibacterial agent

Abstract

The antibacterial properties of CFO/BiOI nanocomposite were investigated in our current study because of their importance in Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Bacillus cereus. MIC, MBC, Disk Diffusion, and IC50 tests cefalotin (CF), amoxicillin (AMX), gentamicin (GM), Trimethoprim‐sulphamethoxazole (SXT), and Ceftriaxone (CRO) antibiotics in concentration 30, 10, 10, 25, and 30 μg were used, respectively. Various techniques such as X‐ray diffraction (XRD), scanning electron microscope (SEM), high‐resolution mapping, and energy dispersive X‐ray spectroscopy (EDAX) have been used to determine the properties of produced nanocomposites. The results showed CFO/BiOI nanocomposite exhibits strong significant biological activity against B. cereus. The results of MBC (minimum bactericidal concentration) and MIC (Minimum Inhibition Concentration) tests for CFO/BiOI nanocomposites on bacteria were examined in the range of 0.12–0.48 and 0.06 to 0.24 mg ml−1, respectively. According to the results,, the minimum IC50 value was determined at a concentration of 0.061 mg ml−1. On the other hand, the most resisting and susceptible bacteria in this method were P. aeruginosa and B. cereus, respectively. These findings are identical to a prior study on antibacterial properties of CoFe2O4 nanoparticles. The MBC endpoint is defined as the lowest concentration, which killed 98% of the bacterial population.

Ionic liquids revolutionizing biomedicine: recent advances and emerging opportunities

“…H-bonds with other substances and properties such as amphipathy and acid-base make them excellent catalysts in the reaction process. 197,198 IL-based catalysts provide numerous benefits compared with traditional catalysts, such as their high adjustability and recyclability, reduced metal and halogen pollution, and enhanced separation between the catalyst and the product. In addition, IL-based catalytic systems offer a notable advantage in terms of reducing neutralization after the reaction, thereby enhancing their sustainability.…”
