Iron oxide nanoparticles (Fe 3 O 4 NPs) are a fascinating field of study due to their wide range of practical applications in environmental and medical contexts. This study presents a straightforward, environmentally friendly method for producing Fe 3 O 4 NPs utilizing β-cyclodextrin (β-CD) as a reducing and capping agent. This approach results in the rapid and effective eco-friendly synthesis of β-CD/Fe 3 O 4 NPs. The properties and characteristics of β-CD/Fe 3 O 4 NPs were investigated using various methods, including ultraviolet−visible (UV/vis) spectroscopy, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), thermogravimetry analysis (TGA), and vibrating-sample magnetometry (VSM). The absorption of β-CD/Fe 3 O 4 NPs caused a distinct peak at 349 nm, as evidenced by the results of UV/vis studies. This peak was attributed to the absorption of surface plasmon resonance. The crystalline nature of β-CD/Fe 3 O 4 NPs was confirmed through XRD analysis. The SEM and TEM analyses have verified the geometry and structural characteristics of β-CD/Fe 3 O 4 NPs. The β-CD/Fe 3 O 4 NPs exhibited remarkable effectiveness in the decomposing efficiency (%) of methylene blue (MB) dye with 52.2, 94.1, and 100% for 0.2, 0.4, and 0.6 g β-CD/ Fe 3 O 4 NPs, respectively. In addition, the highest efficiency in hunting radicals was observed (347.2 ± 8.2 mg/g) at 100 mg/mL β-CD/Fe 3 O 4 NPs; the combination of β-CD/Fe 3 O 4 NPs exhibited remarkable effectiveness in inhibiting the growth of some bacteria that cause infections. The capabilities of β-CD/Fe 3 O 4 NPs for various applications showed that these materials could be used in photocatalytic, antioxidants, and antibacterial. Additionally, the eco-friendly synthesis of these materials makes them a promising option for the remediation of harmful pollutants and microbes.

“…Although it is still unclear how exactly metal or metal oxide NPs work to kill bacteria, Fe 2 O 3 -NPs work by blocking cellular proteins and enzymes from replicating. According to much research, nanoparticles damage the integrity of cells by penetrating both the cell wall and the membrane, as well as by triggering the death of cells by damaging nucleic acids and proteins [ 25 ].…”

“…It was discovered that the bioactive compounds and phytochemicals included in the gum extract of B. malabaricum were responsible for the creation of Fe 2 O 3 -NPs. In that study, the antibacterial activity of synthesized NPs was studied against S. aureus , B. halodurans , and M. luteus with significant results [ 25 ]. The antibacterial potential of Fe 2 O 3 -NPs is of particular relevance in present times because the spread of antibiotic-resistant species has become a key problem for global health [ 10 ].…”

Green approaches for nanoparticle synthesis have emerged as biocompatible, economical, and environment-friendly alternatives to counteract the menace of microbial drug resistance. Recently, the utilization of honey as a green source to synthesize Fe2O3-NPs has been introduced, but its antibacterial activity against one of the opportunistic MDR pathogens, Klebsiella pneumoniae, has not been explored. Therefore, this study employed Apis mellifera honey as a reducing and capping agent for the synthesis of iron oxide nanoparticles (Fe2O3-NPs). Subsequent to the characterization of nanoparticles, their antibacterial, antioxidant, and anti-inflammatory properties were appraised. In UV-Vis spectroscopic analysis, the absorption band ascribed to the SPR peak was observed at 350 nm. XRD analysis confirmed the crystalline nature of Fe2O3-NPs, and the crystal size was deduced to be 36.2 nm. Elemental analysis by EDX validated the presence of iron coupled with oxygen in the nanoparticle composition. In ICP-MS, the highest concentration was of iron (87.15 ppm), followed by sodium (1.49 ppm) and other trace elements (<1 ppm). VSM analysis revealed weak magnetic properties of Fe2O3-NPs. Morphological properties of Fe2O3-NPs revealed by SEM demonstrated that their average size range was 100–150 nm with a non-uniform spherical shape. The antibacterial activity of Fe2O3-NPs was ascertained against 30 clinical isolates of Klebsiella pneumoniae, with the largest inhibition zone recorded being 10 mm. The MIC value for Fe2O3-NPs was 30 µg/mL. However, when mingled with three selected antibiotics, Fe2O3-NPs did not affect any antibacterial activity. Momentous antioxidant (IC50 = 22 µg/mL) and anti-inflammatory (IC50 = 70 µg/mL) activities of Fe2O3-NPs were discerned in comparison with the standard at various concentrations. Consequently, honey-mediated Fe2O3-NP synthesis may serve as a substitute for orthodox antimicrobial drugs and may be explored for prospective biomedical applications.

“…Most photocatalytic reactions are optimized using the traditional kinetic approach, in which the influence of reaction parameters (including photocatalyst concentration, dye molecule concentration, irradiation time, and pH) on the response (percentage degradation; % D ) is investigated by varying one reaction parameter and measuring its influence on % D while keeping all other reaction parameters constant. 263–267 This optimization method assumes that all reaction parameters are independent of one another and that there is no connection between these reaction parameters.
