Jan 21, 2016 · In this paper, we proposed a magnetic actuated pH-responsive hydrogel soft microrobot for drug targeting and delivery. The proposed soft microrobot with eight radial arms has a bilayer structure of biocompatible PHEMA and PEGDA with Fe 3 O 4 nanoparticles. First, as a preliminary characterization of the hydrogels, we examined the swelling and ...Author: Hao Li, Gwangjun Go, Seong Yong Ko, Jong-Oh Park, Sukho Park

Aug 10, 2015 · 3.1. Preparation of Magnetic-Responsive Hemicellulose Hydrogels. The as-prepared hemicellulose hydrogels and ECHHs were free-standing (Figure Figure1 1). The pure hemicellulose hydrogel was yellowish, and the magnetic field-responsive hemicellulose hydrogel was black due to the in situ formation of Fe 3 O 4 particles.Author: Weifeng Zhao, Karin Odelius, Ulrica Edlund, Changsheng Zhao, Ann-Christine Albertsson

A one-pot synthetic methodology for fabricating stimuli-responsive hemicellulose-based hydrogels was developed that consists of the in situ formation of magnetic iron oxide (Fe3O4) nanoparticles during the covalent cross-linking of O-acetyl-galactoglucomannan (AcGGM). The Fe3O4 nanoparticle content controlled the thermal stability, macrostructure, swelling behavior, and magnetization of the ...Author: Weifeng Zhao, Karin Odelius, Ulrica Edlund, Changsheng Zhao, Ann-Christine Albertsson

Magnetic nanoparticle-based drug delivery is a means in which magnetic particles such as iron oxide nanoparticles are a component of a delivery vehicle for magnetic drug delivery, due to their easiness and simplicity with magnet-guidance. Magnetic nanoparticles can impart imaging and controlled release capabilities to drug delivery materials such as micelles, liposomes, and polymers.
