“…Among all the spinel ferrites known today, MnFe 2 O 4 nanoparticles have high surface area, high saturation magnetization, high mechanical hardness and possess excellent chemical stability [15]. Literature survey reveals that manganese ferrite nanoparticles are synthesized by several methods like traditional ceramic methods, oxalate method, sol-gel, chemical co-precipitation, mechanical ball milling, thermal decomposition, hydrothermal, combustion, and micro emulsion method [16][17][18][19].…”

Nanosized manganese ferrite (MnFe 2 O 4 ) particles were prepared by sol-gel method using natural polymers like wheat flour (WF) and potato flour (PF) as surfactants and its structural, morphological, optical and magnetic characteristics were studied by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), scanning electron microscope (SEM), photoluminescence spectroscopy (PL) and vibration sample magnetometer (VSM). Brunauer-Emmett-Teller (BET) surface area test also performed and the results obtained were discussed. The average crystallite size was found to be 23 and 16 nm for WF/MnFe 2 O 4 and PF/MnFe 2 O 4 samples, respectively. Magnetic hysteresis loops confirmed the super-paramagnetic behavior for both the samples. For oxidation of benzyl alcohol to benzaldehyde, the catalytic activity of MnFe 2 O 4 nanoparticles (NPs) was carried out. Antimicrobial and antifungal activity of WF/MnFe 2 O 4 and PF/MnFe 2 O 4 samples were investigated against two Gram-positive bacteria (Staphylococcus aureus, Streptococcus pneumoniae), two Gram-negative bacteria (Pseudomonas aeruginosa, Salmonella paratyphi) and fungus (Candida albicans) using inhibition zone method. Minimum Inhibitory Concentration (MIC) values also calculated to determine susceptibilities of bacteria to drugs and also to evaluate the activity of new antimicrobial agents. The in vitro cytotoxicity of newly synthesized samples were analyzed by MTT assay against MCF-7, A549 and HaCaT cell lines in a dose-dependent fashion. Among these two samples, sample B (using potato flour) shows better response than sample A (using wheat flour) and both the samples were non-toxic to normal cell line. The concentration required to kill 50% of the cell (IC 50 ) was also calculated. Graphical AbstractMnFe 2 O 4 nanoparticles were synthesized by sol-gel method using natural polymers, wheat flour and potato flour, as surfactant. The as-prepared MnFe 2 O 4 was characterized by XRD, FT-IR, SEM, EDX, PL and VSM analysis. The average crystallite size was found to be 23 and 16 nm for WF/MnFe 2 O 4 and PF/MnFe 2 O 4 samples, respectively. Magnetic hysteresis loops confirmed the super-paramagnetic behavior for both the samples. The catalytic activity of MnFe 2 O 4 nanoparticles (NPs) were carried out for oxidation of benzyl alcohol to benzaldehyde. Biological activities like antimicrobial, antifungal and anticancer activities of the samples were investigated. Among these two samples, PF/MnFe 2 O 4 shows better response than WF/MnFe 2 O 4 and both the samples were non-toxic to normal cell line.

“…Manganese ferrite nanoparticles exhibit superior mechanical, luminescent and magnetic properties compared to other existing magnetic ferrite nanoparticles. In recent times, manganese ferrite nanoparticles synthesized by traditional ceramic methods [8][9][10] suffered from drawbacks like uncontrolled particle size, uniformity, poorly defined stoichiometric composition, the presence of impurities during ball milling, chemical inhomogeneity, contamination, and high calcination temperatures [11,12]. Many preparation methods have been used across the globe in the process of synthesis of these magnetic nanoparticles, include sol-gel [13,14], flash combustion [15] citrate gel [16], co-precipitation [17,18], hydrothermal synthesis [19], sol-gel auto combustion [20], micro-emulsion [21] and low temperature combustion methods [22].…”

Manganese ferrite (MnFe 2 O 4 ) magnetic nanoparticles were successfully prepared by a sol-gel self-combustion technique using iron nitrate and manganese nitrate, followed by calcination at 150˝C for 24 h. Calcined sample was systematically characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and vibrational sample magnetometry (VSM) in order to identify the crystalline phase, functional group, morphology, particle size, shape and magnetic behavior. It was observed that the resultant spinal ferrites obtained at low temperature exhibit single phase, nanoparticle size and good magnetic behavior. The study results have revealed the existence of a potent dose dependent cytotoxic effect of MnFe 2 O 4 nanoparticles against 4T1 cell lines at varying concentrations with IC 50 values of 210, 198 and 171 µg/mL after 24 h, 48 h and 72 h of incubation, respectively. Cells exposed to higher concentrations of nanoparticles showed a progressive increase of apoptotic and necrotic activity. Below 125 µg/mL concentration the nanoparticles were biocompatible with 4T1 cells.
