Photoacoustic spectroscopy as a key technique in the investigation of nanosized magnetic particles for drug delivery systems

Green Synthesis Methods of CoFe2O4and Ag-CoFe2O4Nanoparticles Using Hibiscus Extracts and Their Antimicrobial Potential

“…Magnetic spinel ferrite nanoparticles have attracted an incredible attention over the past two decades, due to their improved properties over those exhibited by the "classic" materials with grains size >10 m. The combination of their unique composition and the microstructure leads to a high potential for different applications, such as magnetic recording, magnetic energy storage, catalysis, biomedicine, and waste water treatment [1][2][3][4][5][6][7].…”

Structural and Magnetic Properties of Ultrafine CoFe2O4 Nanoparticles

“…Among various spinel ferrites, CoFe2O4 has received special attraction due to the unique physical properties such as high Curie temperature, large magneto crystalline anisotropy, high coercivity, moderate saturation magnetization, large magnetostrictive coefficient, excellent chemical stability and mechanical hardness (Rajath et al (2008) and Jing Wang et al (2006)). These properties could make the cobalt ferrite technologically important and has been used in high density magnetic recording media (Khandekar et al (2011)), Ferro fluid technology, magnetic resonance imaging enhancement, biosensors, magnetic hyperthermia,(Dong-Hyun Kim et al(2008) and Morais (2009) ) and gas sensors ( Deraz (2010)). …”

Development of cobalt ferrite powder preparation employing the sol–gel technique and its structural characterization

“…Samples (1)(2)(3)(4)(5)(6)(7)(8)(9) were prepared employing the first procedure (a) and samples (10)(11)(12)(13)(14) were prepared employing the second procedure (b). 0.1 M Nitric Acid solution was used as a catalyst for samples 3 and 4 to investigate any possible different effect when changing the catalyst from basic to acidic.…”

“…These properties could make cobalt ferrite a potential candidate for many applications e.g. high frequency magnets, information storage systems, magnetic bulk cores, microwave absorbers [10] and biomedical applications, such as magnetic hyperthermia, drug delivery, magnetic resonance imaging, and biosensors [11,12]. However, the magnetic properties of cobalt ferrite particles have been found to be crucially dependent on the size, shape and purity of these particles, which in turn are dependent on the initial parameters adopted in the process of producing these particles which can change the subsequent microstructure of the material.…”
