Zn-loaded bovine serum albumin nanoparticles (Zn-BSA nanoparticles) were prepared and used as carriers for pH-responsive anticancer drug delivery. Zinc was introduced into this system to increase the stability of the BSA nanoparticles and to load the anticancer drug based on the coordination bonding formation of Zn-BSA and Zn-drug molecules, respectively. The cleavage of either the "Zn-BSA" or ...

Cobalt ferrite nanoparticles were synthesized with coprecipitation or with the hydrothermal method. Stable water suspensions were prepared from the as-synthesized nanoparticles, with the addition of citric acid as a surfactant, and then used for the preparation of deposits under an applied magnetic field. The morphology of the cobalt ferrite nanoparticles was investigated with a transmission el...

The contact of a steel electrode with water dispersion medium in an open-air system leads to the development of various polymorphic iron oxides and oxyhydroxides on the steel surface. Whereas the usage of distilled water causes the obtaining of Fe(II)-Fe(III) layered double hydroxides (green rust) as a primary mineral phase, but in the presence of inorganic 3d-metal water salt solutions, mixed ...

BACKGROUND Nickel ferrite, a kind of soft magnetic materials is one of the most attracting class of materials due to its interesting and important properties and has many technical applications, such as in catalysis, sensors and so on. In this paper the synthesis of NiFe2O4 nanoparticles by the hydrothermal method is reported and the inhibition of surfactant (Glycerol or Sodium dodecyl sulfate)...

Abstract Zinc ferrite nanoparticles were obtained by chemical methods (co-precipitation and thermal decomposition of metalorganic compounds) systematically probed with volume (XRD, VSM), microscopic (TEM) element sensitive probes (ICP-OES, Mössbauer Spectroscopy, XPS, XAFS). Magnetic studies proved the paramagnetic response stoichiometric ZnFe 2 O 4 (ZF) nanoparticles, while superparamagnetic b...

This paper reports a simple and novel process for preparing nano-granular Zn(x)Fe(3-x)O(4) ferrite films (0 </= x </= 0.99) on Ag-coated glass substrates in DMAB-Fe(NO(3))(3)-Zn(NO(3))(2) solutions. The deposition process may be applied in preparing other cations-doped spinel ferrite films. The Zn content x in the Zn(x)Fe(3-x)O(4) films depends linearly on the Zn(2+) ion concentration ranging f...

hard magnetic srfe12o19 (srm) nanoparticles were synthesized by a facile sonochemical reaction. the magnetic nanoparticles were then added to acrylonitrile-butadiene-styrene, polystyrene, polycarbonate, and poly sulfone to make magnetic nanocomposites. the magnetic properties of the samples were also investigated using an alternating gradient force magnetometer. the strontium ferrite nanopartic...

Chemically responsive hydrogels with embedded magnetic nanoparticles are of interest for biosensors that magnetically detect chemical changes. A crucial point is the irreversible linkage of nanoparticles to the hydrogel network, preventing loss of nanoparticles upon repeated swelling and shrinking of the gel. Here, acrylic acid monomers are adsorbed onto ferrite nanoparticles, which subsequentl...

Cobalt manganese ferrite nanoparticles have application potential in the biomedical field, however there is limited information concerning the biological response. The aim of this work was to investigate the cytotoxic potential of cobalt-manganese ferrite nanoparticles in canine mastocytoma tumor cells (C2) and adipose-derived mesenchymal stromal stem cells (ASCs) cultured under a static magnet...
