Encapsulation of Magnetic Nanoparticles with Biopolymer for Biomedical Application

Abstract—Magnetite nanoparticles were synthesized by coprecipitation of Fe2+ and Fe3+ with NH4OH using Spinning Disc Processing (SDP). Chitosan was then coated on the surface of magnetite nanoparticles using SDP. FTIR study and zeta potential measurement confirmed the absorption of chitosan unto the surface of magnetite nanoparticles. Transmission electron microscope (TEM) image showed that the particle sizes are in the range 10 – 200 nm

Magnetite ferrofluids stabilized by sulfonato-calixarenes

Magnetite (Fe304) nanoparticles stabilised by sulfonatocalixarene macrocycles are readily accessible by a rapid in situ co-precipitation, and exhibit ferro-fluidic and superparamagnetic behaviour

(Acetyl­acetonato)(dicyanamido)(1,10-phenanthroline)copper(II) dihydrate

In the title compound, [Cu(C5H7O2)(C2N3)(C12H8N2)]·2H2O, the CuII atom is five-coordinated in a square-pyramidal geometry with two acetyl­acetonate O and two phenanthroline N atoms forming the base. The apical position is occupied by the central N atom of the dicyanamide ligand. The dicyanamide N atoms are each involved in hydrogen bonds to water mol­ecules. There are also hydrogen bonds between both the water mol­ecules and their centrosymmetric pairs, creating a hydrogen-bonded chain along the b-axis direction
