Cobalt–poly(amido amine) superparamagnetic nanocomposites

Block Copolymer-Mediated Formation of Superparamagnetic Nanocomposites

Well-defined diblock copolymers of bicyclo[2.2.1]hept-5-ene-2-carboxylic acid oxiranylmethyl ester, having both anchoring and steric stabilizing blocks in a 1:1 ratio, have been prepared by ringopening metathesis polymerization (ROMP). The epoxy-containing block copolymer stabilized in situ generated iron oxide (γ-Fe2O3) nanoparticles. The epoxy ester group provided strong chelation between the...

Superparamagnetic Nanocomposites Templated with Pyrazole-Containing Diblock Copolymers

Monodisperse maghemite nanoparticles, templated in novel, well-defined pyrazole-containing norbornene-based block copolymers, provided a superparamagnetic nanocomposite with high saturation magnetization at room temperature under an applied magnetic field. The synthesis of the polymer nanocomposites and physical, morphological, and magnetic chracaterization of the nanocomposites are reported. M...

Amine-functionalized SiO2 nanodot-coated layered double hydroxide nanocomposites for enhanced gene delivery

Enzyme immobilised novel core-shell superparamagnetic nanocomposites for enantioselective formation of 4-(R)-hydroxycyclopent-2-en-1-(S)-acetate.

Lipase immobilized novel high surface area core-shell superparamagnetic nanoparticles have been fabricated and used as efficient reusable catalysts for the selective production of pharmaceutically important chiral isomers from meso-cyclopent-2-en-1,4-diacetate.

Biological characteristics of adipose tissue-derived stem cells labeled with amine-surface-modified superparamagnetic iron oxide nanoparticles.

Cell labeling and tracking are becoming increasingly important areas within the field of stem cell transplantation. The ability to track the migration and distribution of implanted cells is critical to understanding the beneficial effects and mechanisms of stem cell therapy. The present study investigated the effects of amine-surface-modified superparamagnetic iron oxide (SPIO) nanoparticles on...
