“…The lattice constant shows an increasing trend with the decrease in crystallites size, while the d XRD increases with increasing crystallite size. A variation of the lattice constant (a) and crystallite size (D XRD ) as a result of different ionic radii, Fe 3+ (tetra: 0.49; octa: 0.64Å), Zn 2+ (tetra: 0.60; octa:0.74 Å), Cu 2+ (tetra: 0.57; octa:0.73Å), Ni 2+ (tetra: 0.58; octa: 0.69 Å), and Co 2+ (tetra: 0.58; octa: 0.74Å) was remarked [12,17]. The expansion of unit cell by the partial substitution of Co 2 with Zn 2+ , Ni 2+ , and Cu 2+ ions [20] could provide a possible explanation.…”

This paper presents the synthesis of metal doped Co ferrites, M0.2Co0.8Fe2O4 (M = Cu2+, Ni2+, and Zn2+) embedded in SiO2 matrix by an innovative sol-gel route. The structural and morphological characterization provided information about the crystalline phases, crystallite size, and the shape of the prepared ferrites. The thermal study depicted the thermal decomposition and stability of the obtained ferrites. X-ray diffraction indicated nanocrystalline ferrites with spinel structure and the lack of crystalline phase impurities, while Fourier transform infrared spectroscopy revealed the presence of functional groups in precursors and ferrite powders. The lattice parameters showed a gradual increase indicating a uniform distribution of divalent metal ions in the Co ferrite lattice. The crystallite size, magnetic moment, super-exchange and deflection of magnetic domain were influenced by the dopant metal ion. The room temperature magnetization indicated a ferromagnetic behavior of the ferrites annealed at 1000 °C and a superparamagnetic behavior of the ferrites annealed at 700 °C.

“…Recently, a study by Ashour et al [25] demonstrated that metal substituted cobalt ferrite NPs, such as copper-cobalt ferrite, zinc-cobalt ferrite, and manganese-cobalt ferrite, inhibit the growth of bacteria and yeast. However, to the best of our knowledge, this is the first report of Nd substituted cobalt NPs with broad-spectrum antimicrobial activity against gram-positive/negative bacterium and yeast.…”

“…Metal combination with cobalt ferrite could obtain new complex materials with improved bioactivity, and such experiments on the antimicrobial aspect of ferrites have achieved success [22,23]. Copper and cobalt substituted cobalt ferrite was reported to influence the microstructure of ferrite nanoparticles (40-50 nm) and exhibit antibacterial activity [8,24,25], Sanpo et al, 2013, Samavati and Ismail, 2017, Maksoud et al, 2019, Ashour et al, 2018. Staphylococcus aureus and Escherichia coli are two of the notorious and the most clinically relevant bacteria known for developing resistance to many commonly used antimicrobials.…”

Neodymium (Nd)-substituted cobalt ferrite nanoparticles (NPs), i.e., CoNdxFe2−xO4 (0.0 ≤ x ≤ 0.2) NPs, were synthesized by the sonochemical method. The compositional characterization was done by scanning electron microscopy (SEM) equipped with energy-dispersive X-ray spectroscopy (EDX) and transmission electron microscopy (TEM). Antistaphylococcal activity was found to be enhanced, i.e., survival rate was 50%, 45%, 40%, and 30% with the increase in the ratio of Nd (0.0 ≤ x ≤ 0.2), whereas anticandidal activity was found efficient, i.e., 9%, 20%, 22%, and 40% survival rate at all the four ratios. The morphogenesis studies indicated that the synthesized metal–ligand, improves the antimicrobial capacity by binding them strongly to the microbial walls. To the best of our knowledge, this is the first report which demonstrates the series of CoNdxFe2−xO4 (0.0 ≤ x ≤ 0.2) NPs being active towards Staphylococcus aureus and Candida albicans and encourages its potential candidature for pharmaceutical and biomedical purposes.

Biocompatible SnO 2 NPs, were synthesized by simple and facile ultrasonic technique, and further studied for antibacterial, anticandidal and invitro cytotoxic activity. The obtained size of synthesized SnO 2 NPs, was 5-30 nm and characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). The evaluation of antibacterial and anticandidal activity of the SnO 2 NPs, was done by determining the minimum inhibitory concentration (MIC), and minimum bactericidal/fungicidal concentration (MBC/MFC), against Escherichia coli and Candida albicans, respectively. The MIC of 0.5 mg/ml and MBC of > 1 mg/ml for E. coli, while as the MIC of 8 mg/ml and MFC > 16 mg/ml for C. albicans, was obtained. Maximum activity for both, bacteria and Candida was achieved, however, to the best of our knowledge, this is the first report of anticandidal activity exhibited by SnO 2 NPs. Treatment of synthesized SnO 2 NPs against the colorectal (HCT-116) cancer cell line, decreased the cell survivability in a dose-dependent manner, as lower dose showed decrease of 73.00%, whereas, higher dosage caused a significant 31.34% decrease in the cell viability. The obtained results confirmed, that the prepared SnO 2 NPs can be the future broad-spectrum antibacterial, anticandidal and anticancer agent, and can be further explored for application in the biomedical field.promising potential for use in the pharmaceutical and biomedical applications. Supporting information summaryThe experimental section includes the detailed procedure for synthesis, characterization, antibacterial, anticandidal and cytotoxic activities of Tin Oxide NPs (SnO 2 NPs), which can be find in supporting information.
