Antimicrobial activity of metal-substituted cobalt ferrite nanoparticles synthesized by sol–gel technique
Abstract
Abstract Metal-substituted cobalt ferrites [M x Co (1− x ) Fe 2 O 4 (M = Zn, Cu, Mn; x = 0.0, 0.25, 0.5, and 0.75)] were synthesized via a sol–gel technique. The ferrite structures were confirmed by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, surface analysis using the Brunauer–Emmett–Teller method, and energy-dispersive X-ray spectroscopy. Antimicrobial activity of these ferrites against selected pathogenic microbes was determined. The structures remained cubic spinel phases after substitution of metals. Substitution strongly influenced the microstructure and homogeneous grain distribution. The particle size of the ferrites increased linearly with increase in their annealing temperature. The surface area of zinc cobalt ferrite nanoparticles (ZCFO) was 52.56 m 2 /g, the average pore size was 1.84 nm, and pore volume was 0.136 mL/g. All ferrites showed antimicrobial activity toward all pathogens selected. Of these, the most powerful was ZCFO, showing zones of inhibition of 13.0 mm against Bacillus subtilis and Staphylococcus aureus and 12.0 mm against Candida albicans . Gamma-irradiated ZCFO nanoparticles (150.0 kGy) maintained higher antimicrobial activity than non-irradiated particles, e.g. being active toward S. aureus (16.0 mm). ZCFO is proposed as a candidate material for industrial and biomedical purposes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
