Magnetic properties of the sets of Fe3O4(core)/CoFe2O4(shell) composite nanoparticles with a core diameter of about 6.3 nm and various shell thicknesses (0, 1.0, and 2.5 nm), as well as the mixtures of Fe3O4 and CoFe2O4 nanoparticles taken in the ratios corresponding to the core/shell material contents in the former case, have been studied. The results of magnetic research showed that the coating of magnetic nanoparticles with a shell gives rise to the appearance of two simultaneous effects: the modification of the core/shell interface parameters and the parameter change in both the nanoparticle’s core and shell themselves. As a result, the core/shell particles acquire new characteristics that are inherent neither to Fe3O4 nor to CoFe2O4. The obtained results open the way to the optimization and adaptation of the parameters of the core/shell spinel-ferrite-based nanoparticles for their application in various technological and biomedical domains.

AbstractThis paper presents a study of heating-induced size and shape change for pre-synthesized composite nanoparticles of ∼2 nm gold cores encapsulated with alkanethiolate monolayers. The results have demonstrated an evolution in size and shape of the nanoparticles towards monodispersed larger core sizes with well-defined and highly-faceted morphologies. The evolved particles were encapsulated with the thiolate shells. The morphological and structural evolutions were characterized using TEM, XRD, UV-Vis and FTIR spectroscopy. While temperature-driven crystal growth is known for non-encapsulated particles, the evolution of the thiolate-encapsulated nanoparticles in solutions into well-defined morphologies represents an intriguing example of temperature manipulations of nanoparticle monodispersity and shape.

In this paper, a novel hIg E aptamer biosensor was designed base on the core-shell Fe3O4@Au magnetic composite nanoparticles (Fe3O4@Au NPs). Firstly, Fe3O4@Au NPs were prepared by one-step reduction process with Fe3O4 nanoparticles (Fe3O4 NPs) as magnetic core and hydroxylamine hydrochloride as deoxidizer. Then, the morphology, composition, and properties of Fe3O4@Au NPs were characterized by scanning electron microscope (SEM), fourier translation infrared spectroscopy (FT-IR), vibrating sample magnetometer (VSM) and so on. Lastly, Human immunoglobulin E (hIg E) was used as the model analyte, a hIg E aptamer biosensor was presented which the hIg E antibody is covalently immobilized as the capture probe on Fe3O4@Au NPs surface, and hIg E aptamer was used as the detection probe. After the hIg E antigen was captured, the ascorbic acid 2-phosphate (AAP) formed ascorbic acid (AA) in the presence of alkaline phosphatase (ALP). The AA reduced the silver ions (Ag+) in the solution to silver metal that preferentially deposited on surface of the Fe3O4@Au NPs. The amount of deposited silver could be quantified using the electrochemical methods. The oxidation current of Ag0 was linear with the concertration of hIg E over the range 0.25~2.0 μg/mL. Therefore, the hIg E aptamer biosensor possessed higher sensitivity, low detection limit and rapid response speed.
