Applications of CoFe2O4 Nanoparticles in Biomedicine

Srinivasan S Y, et al. Nanomedicine, 2018, 13(10): 1221-1238.

Cobalt ferrite (CoFe2O4) nanoparticles (NPs) are a type of magnetic nanomaterial that can provide improved magnetic properties such as coercivity and anisotropy without compromising the inherent advantages of iron oxide nanoparticles to enhance magnetic properties Applicability of nanoparticles (MNPs).
· Synthesis strategies of CoFe2O4 NPs: The synthesis methods of CoFe2O4 NPs include coprecipitation, thermal decomposition, combustion, sol-gel, oxidation and microemulsion.
· Biomedical applications of CoFe2O4 NPs: Their enhanced magnetism holds great promise in almost all aspects of biotechnology, from biosensors, separation and purification, drug delivery, imaging and therapy.

Cobalt Iron Oxide Nanoparticles as Recyclable Catalysts in Organic Synthesis

Kazemi M, et al. Nanotechnology Reviews, 2018, 7(1), 43-68.

Cobalt ferrite nanoparticles (CoFe2O4 MNPs) can be used as catalysts and multifunctional supports for functionalization of metals, organic catalysts, especially based on their recovery and reusability capabilities. Here are some applications of CoFe2O4 MNP nanocatalysts in organic synthesis.
· The types of oxidation catalytic reactions catalyzed by CoFe2O4 MNP include alcohol oxidation and hydrocarbon oxidation. For example, when pure CoFe2O4 was applied as catalyst (5 mg), 16.2% of cyclohexane conversion and 92.4% of selectivity for cyclohexanone and cyclohexanol were observed after 6 h. The catalyst can be readily recovered by an external magnet.
· CoFe2O4 MNPs can catalyze carbon-carbon and heteroatom (oxygen or sulfur) coupling reactions. For example, the magnetically recyclable palladium catalyst (CF-MNPs) was created by adding Pd nanoparticles directly during the synthesis of cobalt ferrite nanoparticles. In the presence of this CF-MNPs catalyst, symmetrical and unsymmetrical biaryl derivatives were prepared in reasonable yields.

Preparation of Lanthanum-Doped Spinel Cobalt Iron Oxide Nanoparticles for Environmental Applications

Mariosi F R, et al. Ceramics International, 2020, 46(3), 2772-2779.

Lanthanum-doped CoFe2O4 nanoparticles can be successfully synthesized via a low-temperature sol-gel method. The magnetic properties, coupled to the observed decrease in band gap and increased surface area, render the prepared materials ideally suited for applications as advanced adsorbent materials.
Synthesis of lanthanum-doped CoFe2O4 nanoparticles
· Reagents in a molar ratio of 1:2:3 were used to produce a nominal sample of 10 mmol of cobalt ferrite (CoFe2O4) via sol-gel synthesis. Fe (NO3)3.9H2O, Co(NO3)2.6H2O and citric acid were dissolved in 20 mL of ultra pure water.
· Three other compositions also were prepared using La(NO3)3.6H2O to produce samples with the formula CoLaxFe2-xO4, with x values of 0.025, 0.05 and 0.1.
· In order to obtain the products, the precursors in solution were heated to 85 °C for 1.25 h under magnetic stirring until a gel was achieved.
· Subsequently, the gel was dried at 110 °C for 24 h in order to obtain a xerogel, which was transferred to an alumina crucible and treated in a muffle furnace at 300 °C for 20 h to ensure the complete decomposition of organics.
