A novel thermo-induced self-bursting microcapsule with magnetic-targeting property.
TL;DR: A novel type of monodisperse thermo-induced self-bursting microcapsules with oil cores for encapsulating lipophilic substances and the Fe3O4/PNIPAM shell enables the microcapsule to undergo magnetic-guided targeting delivery, have no unintended drug leakage during micro Capsule transport, and exhibit thermo -triggered drug release.

Poly(n-isopropylacrylamide)-based hydrogel coatings on magnetite nanoparticles via atom transfer radical polymerization
TL;DR: A model intelligent hydrogel system based on the temperature responsive polymer poly(n-isopropyl acrylamide) (PNIPAAm) to obtain magnetically responsive core-shell nanocomposites shows great promise for further biomedical applications.

TL;DR: In this article, NiFe2O4 nanoparticles of size ⩽10 nm were investigated by using transmission electron microscopy and x-ray scattering and the results of those two types of macroscopic tests completely reject a simple single-domain particle model but readily support the two-component scheme of a particle as consisting of a core with a uniform magnetization and a surface layer of comparable thickness stowed with a spin-glass-like arrangement.

Magnetic Properties of Stable Dispersions of Subdomain Magnetite Particles
Robert Kaiser,G. Miskolczy +1 more
TL;DR: In this article, stable colloidal dispersions of subdomain-size magnetic particles have been prepared that retain their liquid characteristics in the presence of a magnetic field, correcting for the formation of a nonmagnetic surface mantle one unit cell thick.
