    Abstract: Disclosed are the nanoparticle and the method for the same, and the preparing method includes steps of mixing polyethylenimine (PEI) with the poly(acrylic acid)-bound iron oxide (PAAIO) to form a PEI-PAAIO polyelectrolyte complex (PEC) and mixing the PEI-PAAIO PEC with genetic material such as plasmid DNA to form the PEI-PAAIO/pDNA magnetic nanoparticle. The PEI-PAAIO/pDNA magnetoplex is highly water dispersible and suitable for long term storage, shows superparamagnetism, low cytotoxicity, high stability and nice transfection efficiency, and thus the PEI-PAAIO PEC can replace PEI as a non-viral gene vector.

    Abstract: A method for manufacturing a rubber magnet with a colored facial gum material layer and a rubber magnet thereof. A colored gum material layer is paved on a surface of the rubber magnet. A surfactant is added into the colored gum material layer. An identical surfactant or a surfactant with very close polarity is added into the material of the rubber magnet, whereby the surfaces of the gum material layer and the rubber magnet can tightly adhere to each other without easy peeling. In addition, antiscaling agent, wetting/spreading agent and defoaming agent are added into the gum material layer to fully wet the color and uniformly spread the color over the gum material so as to enhance the evenness of the color.

    Abstract: A method for producing a permanently-magnetic part, made from a polymeric support material filled with magnetic filler materials on the basis of silicon caoutchouc, hot-vulcanized from at least one starting material, in which the at least one starting material of the silicon caoutchouc is mixed prior to vulcanization with 50 to 95% by weight of high energy ferrite particles of a density of 5.0 to 5.2 g/cm3 and an average particle size of 1.5 to 2.5 μm as the magnetic filler material and is homogenized. Subsequently, the homogenized mixture is introduced into a mold cavity by a temperature-regulated screw and is cross-linked by vulcanization in the mold cavity by the application of heat for forming the molding, wherein during cross-linking a static magnetic field is applied to the mold cavity and the magnetic filler materials are magnetized and aligned in the silicon caoutchouc being cross-linked.

    Abstract: Contaminants in food or pharmaceuticals derived from the handling equipment are detected by known detection devices in product flow by the method of detecting particulate magnetic mineral dispersed in the handling equipment or the film used to wrap the food. The minerals magnetic field is detected and the signal generated thereby causes rejection of the product which contains the contamination. A method of making moulded parts of the handling equipment and wrapping film by incorporation of ferrimagnetic ceramic fillers is disclosed. Compositions for moulding and film extrusion with 10-50% of magnetite and other magnetic fillers with a size range of 0.5-20μ are disclosed.
