Hermetically-Coated Superparamagnetic Fe2O3 Particles with SiO2 Nanofilms

Teleki A., Suter M., Kidambi P.R., Ergeneman O., Krumeich F., Nelson B.J., Pratsinis S.E., ETH Zürich, CH

Magnetic nanoparticles are frequently coated with SiO2 to improve their functionality and bio-compatibility in a range of biomedical and polymer nanocomposite applications. In this paper, a scalable flame aerosol technology is used to produce highly [...]

Hyperhtermia effect of surface-modified magnetite nanoparticles in a microfluid system

Lin C.Y., Ho K.C., National Taiwan University, TW

Fe3O4 nanoparticles (NPs) was first synthesized via coprecipiatation. After synthesis and purification of the Fe3O4 NPs, poly(acrylic acid) (PAA) was coated on them at specified conditions. The coating process is not possible at pH higher [...]

Synthesis of superparamagnetic magnetite nanoparticles for thermoresponsive drug delivery

Lin C.Y., Ho K.C., National Taiwan University, TW

Superparamagnetic magnetite nanoparticles (MNPs) were synthesized via modified coprecipitation method and their physical properties were examined. The crystal structure of Fe3O4 nanoparticles (NPs) was confirmed by X-ray diffraction. From the dynamic laser scattering analysis, the [...]

Design of Magnetic Nanoparticles for Purification of His-tagged Recombinant Proteins

Mohapatra S., Pal D., Ghosh S.K., Pramanik P., Indian Institute of Technology, IN

Manipulation of proteins effectively for in-vitro study is an important step of research in the area of proteomics. The expression of recombinant proteins with histidine fusion tags(6xHis) is widely used to ease their purification from [...]

Magnetic Driven Assembly of Colloidal Particles onto Patterned Surfaces

Yellen B., Friedman G., Drexel University, US

A two-dimensional array of colloidal particles can be utilized in constructing devices and materials for photonic, electronic, magnetic and sensor applications. Several methods for patterning colloidal particles arrays have emerged in the recent past, including [...]
