Conversion of ferritin ferrihydrite core to magnetite by gold ions binding and the derived nanoparticle formation

Inspired by the multi-functionalities of vegetal extracts, we first focused on developing a new gold nanoparticle (AuNP) synthesis method using tomato extract ( Solanum lycopersicum Mill, Carmen

Enhanced Magnetic Hyperthermia of Magnetoferritin through Synthesis at Elevated Temperature

Iron oxide nanoparticles have attracted a great deal of research interest in recent years for magnetic hyperthermia therapy owing to their biocompatibility and superior thermal conversion efficiency.

Small-Angle Scattering on Magnetoferritin Nanoparticles

Magnetoferritin is a synthetically prepared magnetic bio-complex, consisting of apoferritin shell and iron-based nanoparticles. Superparamagnetic behaviour, nanoscale size (about 12 nm) and

Mechanisms of ferritin assembly studied by time-resolved small-angle X-ray scattering

The assembly reaction of Escherichia coli ferritin A was studied using time-resolved small-angle X-ray scattering (SAXS) and it was suggested that local electrostatic interactions are also responsible for the ionic-strength dependence of the assembly rate and are, on average, repulsive.

Low-field and high-field magnetic resonance contrast imaging of magnetoferritin as a pathological model system of iron accumulation

Various pathological processes including neurodegenerative disorders are associated with the accumulation of iron, while it is believed that a precursor of iron accumulation is ferritin.

Magnetic Nanoparticle Systems for Nanomedicine—A Materials Science Perspective

Iron oxide nanoparticles are the basic components of the most promising magneto-responsive systems for nanomedicine, ranging from drug delivery and imaging to hyperthermia cancer treatment, as well

Size-dependent properties of magnetoferritin

It is found that K is enormously enhanced with respect to the maghemite bulk value and that it increases with decreasing size and the Mössbauer spectra suggest that low-symmetry atomic sites, probably located at the particle surface and at the interfaces between different crystalline domains, are the likely source of the enhanced magnetic anisotropy.

Biomimetic Synthesis and Characterization of Magnetic Proteins (Magnetoferritin)

A new synthesis of the magnetic protein magnetoferritin is reported. Addition of increments of Fe(II) to anaerobic solutions of the demetalated protein, apoferritin, at pH = 8.6 and 65 °C, followed

Structure and in vitro biological testing of water-based ferrofluids stabilized by monocarboxylic acids.

It is shown that despite the good stability of the systems a significant part of the magnetite nanoparticles are in aggregates, whose inner structure depends on the stabilizer used, and an incomplete coating of magnetite particles is concluded in the case of myristic acid stabilization.

Structural Aspects of the Growth Mechanism of Copper Nanoparticles Inside Apoferritin

It is well known that some of the metal ions remain bound to apoferritin when incubating apoferritin with metal ions. In this study a structural insight, from X-ray absorption spectroscopy (XAS) and

Magnetoferritin: in vitro synthesis of a novel magnetic protein.

Transmission electron microscopy and electron diffraction analysis indicate that the entrapped mineral particles are discrete 6-nanometer spherical single crystals of the ferrimagnetic iron oxide magnetite (Fe3O4).

Influence of the physiochemical properties of superparamagnetic iron oxide nanoparticles on amyloid β protein fibrillation in solution.

The effect of thickness and surface charge of the coating layer of SPIONs on the kinetics of fibrillation of Aβ in aqueous solution is demonstrated and suggests that in addition to the presence of particles, which affect the concentration of monomeric protein in solution, there are also effects of binding on the protein conformation.

The Faraday effect of natural and artificial ferritins

Differences in the Faraday rotation spectra and their magnetic field dependences allow discrimination between magnetoferritin with maghemite and magnetite cores which can be very useful in biomedicine.
