Abstract This work reports the fabrication of magnetite (Fe 3 O 4 ) nanoparticles (NPs) coated with various biocompatible surfactants such as glutamic acid (GA), citric (CA), polyethylene glycol (PEG), polyvinylpyrrolidine (PVP), ethylene diamine (EDA) and cetyl-trimethyl ammonium bromide (CTAB) via co-precipitation method their comparative inductive heating ability for hyperthermia (HT) applications. X-ray electron diffraction analyses validated formation well crystallined inverse spinel...
Over the past decade, transition metal-based ferrite nanostructures, displaying MFe2O4 stoichiometry (M2+ cations, e.g., Mn, Co, Ni and Zn), have been devised examined primarily owing to their promising applications in cancer nanomedicine. Among these multi-functional spinel ferrites, manganese (MnFe2O4) deserves special attention because it unveils exciting magnetic properties, high chemical stability, excellent biocompatibility, which are crucial prerequisites for advanced biomedical...
Graphene quantum dots (GQDs) are a newly developed class of material, known as zero-dimensional nanomaterials, with characteristics derived from both carbon (CDs) and graphene. GQDs exhibit several ideal properties, including the potential to absorb incident energy, high water solubility, tunable photoluminescence, good stability, drug-loading capacity, notable biocompatibility, which make them powerful tools for various applications in field biomedicine. Additionally, can be incorporated...

Nanorods of YPxV1−xO4:Ln3+ (Ln3+ = Dy3+, Eu3+, Sm3+) have been synthesized hydrothermally. The substitution vanadium (V5+) by phosphorous (P5+) ions in YVO4 was confirmed X-ray diffraction studies and also supported Fourier transform infrared spectroscopy, transmission electron microscopy photoluminescence (PL) studies. energy transfer (ET) rate to the activator can be controlled either concentration or doping with P crystal. ET is reduced due increase separation between ions. This has...
Nanoparticle-mediated starvation therapy is a promising therapeutic approach for cancer treatment. Here, we report novel nanosystem (GOx@PEG-MnFe2O4) composed of glucose oxidase (GOx) loaded in polyethylene glycol (PEG) modified manganese ferrite (MnFe2O4) nanoparticles (NPs) therapy. GOx catalyzes the oxidation to gluconic acid and hydrogen peroxide (H2O2) by consuming oxygen (O2) an acidic environment. Meanwhile, NPs can catalyze H2O2 generate O2, which, turn, aids depletion eliminate...
Luminescence intensity of rare-earth doped materials can be varied depending on shape particles, capping agent, and heat-treatment. This is related to the non-radiative rate possessed by material. Here, we observed high quenching luminescence Eu3+ GdPO4 prepared in water (H2O) medium. On contrary, ethylene glycol (EG) medium, it shows luminescence. recovered when nanorods H2O medium heated above 700 °C. transforms hexagonal monoclinic structure following removal water. enhanced changing from...
A size tunable synthesis of mesoporous MgFe2O4 magnetic nanoassemblies (MMNs) through a PEG-diacid mediated polyol method is reported. The coated MMNs exhibit significant specific surface area 92 m2 g-1 and saturation magnetization 57 emu g-1.
