Therapeutic Study

This study was performed to investigate the biocompatibility (BC), magnetothermal effect, and DNA binding biological characteristics of manganese zinc ferrite nanoparticles (Mn0.6Zn0.4Fe2O4-NPs (MZF-NPs)) coated with pegylated manganese (PEG-MZF-NPs). Their functions as gene transfer carrier for gene therapy and magnetic medium for tumor hyperthermia were also explored. The manganese zinc ferrite nanoparticles were synthesized through high temperature cracking, and their characterizations were discovered. Hemolysis test and MTT assay were performed to evaluate biocompatibility, and their self-heating effects in the alternating magnetic field were investigated. PEG-MZF-NPs with different concentrations were measured by using 7.0 T Micro-MR scanner (MRI) to calculate the T2 value and r2 relaxation rate of each sample. The CD44-shRNA plasmids were constructed, and their ability to bind PEG-MZF-NPs were examined. The DNA release from PEG-MZF-NP/DNA complex and protection of DNA from nuclease digestion were also detected. After CD44-shRNA-EGFP were transfected into the ovarian cancer SK-OV-3 cells by using PEG-MZF-NPs as carriers, the transfection efficiency was detected by a flow cytometer and expression of CD44 mRNA and protein in cells was detected using RT-PCR and Western blot, respectively. We successfully prepared PEG-MZF-NPs with favorable dispersity, magnetic responsiveness, and BC. Typically, the excellent magnetothermal effect can be used for a tumor magnetothermal therapeutic study. In vitro MRI showed the application potential for being magnetic resonance T2 relaxation contrast agents and the possibility to achieve goal of integration of targeting diagnosis and treatment. The CD44-shRNA plasmids have been successfully constructed and concluded that PEG-MZF-NPs may serve as gene transfer carriers for gene therapy.

The Impact

This study aims to synthesize manganese zinc ferrite nanoparticles (Mn0.5Zn0.5Fe2O4 NPs) using a green chemistry synthesis technique and investigate their efficiency as nanofertilizers for squash plant (Cucurbita pepo L). In this work, Mn0.5Zn0.5Fe2O4 NPs were successfully prepared at different temperatures via simple template-free microwave-assisted hydrothermal route and used as foliar nanofertilizers for squash plant. The physicochemical characteristics of the as-prepared ferrites were investigated using X-ray diffraction (XRD), N2 adsorption-desorption isotherm, field emission scanning electron microscopy (FE-SEM) and high resolution transmission electron microscopy (HR-TEM) techniques. The prepared nanoferrites showed type IV adsorption isotherm characteristic for mesoporous materials. FE-SEM and HR-TEM imaging proves the production cubic shaped nanoparticles with average particle size 10-12 nm. Also the impact of using different concentrations of Mn0.5Zn0.5Fe2O4 NPs on vegetative growth, minerals content and the yield of squash plant were investigated. The result showed that the highest vegetative growth for squash appeared with plants supplied by Mn0.5Zn0.5Fe2O4 NPs synthesized at 180°C. On the contrary, the yield of squash recorded the best with 160°C. As for the use of different concentrations of Mn0.5Zn0.5Fe2O4 NPs, it was found that the use of the lowest concentrations gave the highest values of vegetative growth and yield characters. The chemical content of the squash plant differs from the components of proximate value and the elements according to the temperature used in the composition of the compound Mn0.5Zn0.5Fe2O4 NPs and its concentrations. Accordingly, these nanoferrites can be considered as good candidates for Cucurbita pepo L fertilization.
