Biocompatible magnetic core-shell nanocomposites for engineered magnetic tissues.
The inclusion of magnetic nanoparticles into biopolymer matrixes enables the preparation of magnetic field-responsive engineered tissues. Here we describe a synthetic route to prepare biocompatible core-shell nanostructures consisting of a polymeric core and a magnetic shell, which are used for this purpose. We show that using a core-shell architecture is doubly advantageous. First, gravitation...
متن کاملMultifunctional glucose biosensors from Fe3O4 nanoparticles modified chitosan/graphene nanocomposites
Novel water-dispersible and biocompatible chitosan-functionalized graphene (CG) has been prepared by a one-step ball milling of carboxylic chitosan and graphite. Presence of nitrogen (from chitosan) at the surface of graphene enables the CG to be an outstanding catalyst for the electrochemical biosensors. The resulting CG shows lower ID/IG ratio in the Raman spectrum than other nitrogen-contain...
متن کاملSynthesis and characterization of core-shell Fe3O4-gold-chitosan nanostructure
BACKGROUND Fe₃O₄-gold-chitosan core-shell nanostructure can be used in biotechnological and biomedical applications such as magnetic bioseparation, water and wastewater treatment, biodetection and bioimaging, drug delivery, and cancer treatment. RESULTS Magnetite nanoparticles with an average size of 9.8 nm in diameter were synthesized using the chemical co-precipitation method. A gold-coated...
متن کاملSynthesis and Characterization of a Novel Fe3O4-SiO2@Gold Core-Shell Biocompatible Magnetic Nanoparticles for Biological and Medical Applications
Objectives: The study of core-shell magnetic nanoparticles has a wide range of applications because of the unique combination of the nanoscale magnetic core and the functional shell. Characterization and application of one important class of core-shell magnetic nanoparticles (MNPs), i.e., iron oxide core (Fe3O4/γ-Fe2O3) with a silica shell and outer of gold (Fe3O4-SiO2@Gold (FSG)) in Boron Neut...
متن کاملSurfactant Removal from Mesoporous Silica Shell of Core-Shell Magnetic Microspheres by Modified Supercritical CO2
In this paper, a kind of core–shell magnetic mesoporous microspheres of Fe3O4@SiO2@meso-SiO2 with high surface areawas prepared, where magnetic Fe3O4 nanospheres were used as the inner core, tetraethyl orthosilicate (TEOS) as silica source, and cetyltrimethylamonium bromide (CTAB) as pore forming agent. Methanol-enhanced s...
