New Findings on Nanoparticles Described by Investigators at Thapar University (Biocompatibility and superparamagnetism in novel silica/CaFe2O4 nanocomposite)

By a News Reporter-Staff News Editor at Physics Week -- Investigators publish new report on Nanoparticles. According to news reporting originating in Patiala, India, by VerticalNews journalists, research stated, "Calcium ferrite nanoparticles (CaFe2O4 NPs) have been successfully passivated by silica coating. The particle size distribution was observed in the narrow range of 3-6 nm, without any agglomeration, suggesting the stabilization of high surface energy and magnetic interaction on the nanoparticles' surface, due to silica."

The news reporters obtained a quote from the research from Thapar University, "Presence of amorphous silica resulted in less peak intensities of the orthorhombic CaFe2O4 core. The characteristic IR bands of silica confirmed its coating thereby making the nanocomposite viable for bio-conjugation (active silanol groups in the silica layer covalently attach to biomolecules). The nanocomposite exhibited superparamagnetic behavior (M-s=8.55 emu/g) and high biocompatibility below 500 mu g/ml."

According to the news reporters, the research concluded: "The nanosized, superparamagnetic and highly biocompatible synthesized nanocomposite finds potential applications in biomedicinal hybrids."
