This study aimed to modify the biological response of cells to ionizing radiation by combination therapy using radio-sensitizer agent and anticancer drug. Super paramagnetic iron oxide nanoparticles (SPIONs) were prepared and used with gemcitabine (Gem). These two agents were encapsulated simultaneously intopoly (D, L-lactic-co-glycolic acid) (PLGA) to form multifunctional drug delivery system....

In the present study, Fe3O4 super paramagnetic nanoparticles were synthesized via co-precipitation of Fe3+ and Fe2+ chloride salts in the presence of ammonia Solution. The product was characterized by Fourier Transform Infrared spectroscopy (FT-IR), Transmission Electron Microscopy (TEM), and zeta–potential particle size distributing methods. The synt...

Magnetic nanoparticle Fe304 have super paramagnetic, biological cell compatibility, low toxicity, antibiosis and bacteriostasis, drug loading, sustained release thermal effect. Using magnetic nanoparticies as source, masoporous glass two-dimensional bone framework was synthesized under the action of external field, which provides growth space for repair, proliferation metabolism, contribute to ...

Preparation of iron salts Fe + 3 Fe+2 This study aims to prepare super-magnetic nanoparticles coated with chitosan-CS SPIONs in an easy and inexpensive chemical way, which is the method co-precipitation mediated aqueous solution mixing it a chitosan CS dissolved dilute citric acid 1 % precipitation this mixture NaOH sodium citrate as surfactant inside closed system using inert atmosphere for ni...

A new approach for clustering is proposed. This method is based on an analogy to a physical model; the ferromagnetic Potts model at thermal equilibrium is used as an analog computer for this hard optimization problem. We do not assume any structure of the underlying distribution of the data. Phase space of the Potts model is divided into three regions; ferromagnetic, super-paramagnetic and para...
