Green synthesis and characterization of Mg0.93Na0.07O nanoparticles for antimicrobial activity, cytotoxicity and magnetic hyperthermia

Green Synthesis of Magnesium Oxide Nanoparticles and Nanocomposites for Photocatalytic Antimicrobial, Antibiofilm and Antifungal Applications

“…Metal oxide and metal NPs have wide applications in different biochemical and medical applications, such as catalysis [9], tissue engineering [10], antibacterial and anticancer agents [11][12][13]. Among metal oxide NPs, MgO NPs have attracted attention for their high stability, biocompatibility and their antipathogenic (antiviral, antimicrobial and antifungal) activity [14,15]. MgO is an eco-friendly, economically viable and industrially important NP that stands out for its unique physicochemical properties, including outstanding refractive index [16], excellent corrosion resistance [17], high thermal conductivity [18], excellent optical transparency [19], mechanical strength [20], dielectric resistance [21], stability [22], flame-resistance [23], physical strength [24,25] and low electrical conductivity [26][27][28].…”

High dielectric-energy storage and ferromagnetic-superparamagnetic properties: tetra-doping CuO nanocompositions

“…Sequentially, these magnetically ordered areas can powerfully overlap and extent over the total structure which producing a condition comparable to a ferromagnetic state and this type can continue to room temperature or above [75]. There is an additional mechanism termed F-center (FC, oxygen vacancies mediated ferromagnetism) that it is a sub-mechanism or an equivalent path to the BMPs mechanism to describe the ferromagnetic characteristics at room temperature in undoped or transition (Mn, Fe, Co, Ni) or rare earth (Gd, Ce, Sm) metals lightly doped oxides semiconductor [76][77][78][79]. In the F-center mechanism, the electrons trapped by the oxygen vacancies can act as coupling F-centers, over which the doped magnetic ions like Mn, Fe, Co, Ni, Gd and Sm align in ferromagnetic order.…”
