Antibacterial and Antifungal Activity of Novel Synthesized Neodymium-Substituted Cobalt Ferrite Nanoparticles for Biomedical Application

“…Cobalt ferrite has been an interesting field in the past few decades for its unique and controllable characteristics and its potential use in biomedical applications, such as enhanced drug stability/solubility, and reduced side effects [17][18][19][20][21], Amiri andShokrollahi, 2013, Hathout et al, 2017. 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.…”

Fabrication, mechanical, and electromagnetic studies of cobalt ferrite based‐epoxy nanocomposites

“…Many strategies have been established to get a variety of magnetic NPs, such as Co, Ni, Fe, Fe‐O, M‐Fe 2 O 4 alloys, and so on. [ 9 ] In magnetic materials, magnetite Fe 2 O 4 finds widespread application in many fields, such as environmental remediation, biotechnology/biomedicine, microwave absorption, catalysis, biomolecular separation, etc. [ 10,11 ] Generally, Fe 2 O 4 NPs could be developed with diverse methods such as coprecipitation of Fe 2+ and Fe 3+ , solvothermal/hydrothermal, thermal decomposition, and sol‐gel method.…”

Co0 superparamagnetic nanoparticles stabilized by an organic layer coating with antimicrobial activity

“…15 Besides, little information is available in the literature on the antimicrobial activity of metallic cobalt nanoparticles (Co 0 -NPs). However, studies show the use of complex nanostructured systems based on cobalt, such as, for example; rare earth element (REE) cerium (Ce 3+) doped CoFe 2 O 4 nanoparticles, 16 nitrogen-rich carbon-coated bismuth/cobalt nanoparticles, 17 cobalt ferrite-chitosan, 18 and Co-doped TiO 2 nanostructures, 19 which have presented good antimicrobial behavior in Gram-positive and Gram-negative bacteria. Many synthetic methods have been developed to prepare MNPs, including the thermal decomposition method, 20 hydrothermal microemulsion process, 21 high temperature solution phase method, 22 and solvothermal process.…”
