“…The amount of induced heat by MNPs is quantified in terms of the specific loss power (SLP). SLP depends on several physical and magnetic properties of the particles including particle size, , size distribution, , and magnetocrystalline anisotropy ( K ), , as well as several extrinsic factors including the frequency ( f ) and amplitude of the applied magnetic field ( H ), , viscosity of the carrier medium (η), and the concentration of the particles . In general, SLP values that arise from the relaxation processes (Néel and Brownian) are roughly proportional to K , and inversely proportional to the size of the nanoparticles .…”

In this study, the ac magnetic hyperthermia responses of spinel CoFe 2 O 4 , MnFe 2 O 4 , and NiFe 2 O 4 nanoparticles of comparable sizes (∼20 nm) were investigated to evaluate their feasibility of use in magnetic hyperthermia. The heating ability of EDT-coated nanoparticles which were dispersed in two different carrier media, deionized water and ethylene glycol, at concentrations of 1 and 2 mg/mL, was evaluated by estimating the specific loss power (SLP) (which is a measure of magnetic energy transformed into heat) under magnetic fields of 15, 25, and 50 kA/m at a constant frequency of 195 kHz. The maximum value of SLP has been found to be ∼315 W/g for CoFe 2 O 4 and ∼295 W/g for MnFe 2 O 4 and NiFe 2 O 4 nanoparticles. We report very promising heating temperature rising characteristics of CoFe 2 O 4 , MnFe 2 O 4 , and NiFe 2 O 4 nanoparticles under different applied magnetic fields that indicate the effectiveness of these nanoparticles as hyperthermia agents.

“…Cobalt ferrite (CoFe 2 O 4 ) nanoparticles have been used in many biomedical applications owing to the unique properties like large magnetocrystalline anisotropy, high Curie temperature, large magnetostriction coefficient, non-toxicity and good chemical stability; hence they have the potential as magnetic hyperthermia agent [75][76][77][78][79][80][81][82][83]. In addition to this property, unique tendency of cobalt ferrite nanoparticles is to form growing chains on the application of an alternating magnetic field.…”

Magnetic nanoferrites have shown immense potential in the biomedical applications due to its ability to precisely control the behavior by application of external magnetic field. Superior magnetic properties of ferrites make them promising nanoagents in various applications like targeted drug delivery, magnetic separation, biosensors, MRI, antimicrobial agents and magnetic hyperthermia (MHT). The challenge is to maintain the high magnetization which decreases when size is reduced to nanoscale, hence the engineering of these nanoferrites is of prime importance, where selection of appropriate synthesis method plays very important role. Hence the parameters like morphology, biocompatibility, chemical and physical properties affect the efficiency of nanoferrites in biomedical applications. IntroductionNanoferrites have numerous biomedical applications due to their size comparable to biological molecules and excellent magnetic properties, which are prerequisites for all biomedical applications. Due to the transparency of biological tissues to magnetic field, various properties can be tuned when nanoferrites interacts with magnetic field. These unique properties of magnetic nanoferrites along with the stability, sensitivity and easy functionalization makes them the future biomedical materials in numerous applications like targeted biosensors, drug delivery, MRI imaging, magnetic separation, antimicrobial agents, magnetic hyperthermia, detoxification, photoablation therapy [1,2]. The magnetic characteristics of ferrite nanoparticles strongly affect its performance in biomedical applications. For example, saturation magnetization is Sarveena (B)

“…Over the past decade, some studies revealed the antimicrobial activity of the cobalt ferrite and substituted cobalt ferrite nanoparticles, M x Co 1-x Fe 2 O 4 (M = Zn, Cu, Mn), on pathogenic and multidrug resistant bacterial strains [15][16][17][18][19]. An overview of the literature shows also studies on the antimicrobial properties of rare earth substituted cobalt ferrite nanoparticles CoFe 2-x RE x O 4 (RE 3+ = La 3+ , Dy 3+ , Yb 3+ , Gd 3+ , Ce 3+ ) [20,21].…”

“…The proper choice of the synthesis method will play an important role on the composition, structure and morphology of the oxides, influencing also their biological activities, including antimicrobial activity. Žaln ėravičius et al [20] have studied the influence of the nanoparticle size on the antimicrobial activity and have reported that this activity was increased with the decreasing of the particle size.…”

Nanosized CoFe1.8RE0.2O4 (RE3+ = Tb3+, Er3+) ferrites were obtained through wet ferritization method. These ferrites were characterized by X-ray diffraction (XRD), scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM/HR-TEM), Fourier transform infrared spectroscopy (FTIR), Mössbauer spectroscopy and magnetic measurements. The XRD results revealed that the average crystallite size is 5.77 nm for CoFe1.8Tb0.2O4 and 6.42 nm for CoFe1.8Er0.2O4. Distribution of metal cations in the spinel structure estimated from X-ray diffraction data showed that the Tb3+ and Er3+ ions occupy the octahedral sites. TEM images indicated the presence of polyhedral particles with average size 5.91 nm for CoFe1.8Tb0.2O4 and 6.80 nm for CoFe1.8Er0.2O4. Room temperature Mössbauer spectra exhibit typical nanoscaled cobalt ferrite spectra in good agreement with XRD and TEM data. The saturation magnetization value (Ms) is 60 emu/g for CoFe1.8Tb0.2O4 and 80 emu/g for CoFe1.8Er0.2O4. CoFe1.8RE0.2O4 nanoparticles showed similar antimicrobial efficacy against the five tested microbial strains, both in planktonic and biofilm state. The results highlight the promising potential of these types of nanoparticles for the development of novel anti-biofilm agents and materials.
