We have revealed the fundamental mechanism of specific Cs(+) adsorption into Prussian blue (PB) in order to develop high-performance PB-based Cs(+) adsorbents in the wake of the Fukushima nuclear accident. We compared two types of PB nanoparticles with formulae of Fe(III)4[Fe(II)(CN)6]3·xH2O (x = 10-15) (PB-1) and (NH4)0.70Fe(III)1.10[Fe(II)(CN)6]·1.7H2O (PB-2) with respect to the Cs(+) adsorpt...
The first photocontrollable magnetic nanoparticles containing CdS and Prussian blue (PB) have been created using reverse micelles as nanoreactors. Photoinduced electron transfer from CdS to PB in the reverse micelle changed the magnetic properties of the composite nanoparticles from ferromagnetic to paramagnetic. The magnetization in the ferromagnetic region below 4 K was substantially decrease...
A one-step synthesis of Prussian blue nanoparticles possessing a concentration gradient of Gd3+ counterions, g-Gd-PB, has been developed, and the potential for the particles to perform as both MRI positive contrast agents and photothermal therapy agents is demonstrated. The synthesis of potassium/gadolinium ironhexacyanoferrate is performed under increasing concentration of Gd3+ ions forming pa...
Edged plane pyrolytic graphite electrode (EPPGE) was modified with and without Prussian blue (PB) nanoparticles and polyaminobenzene sulphonated single-walled carbon nanotubes (SWCNTPABS) using the chemical deposition method. The electrodes were characterised using microscopy, spectroscopy and electrochemical techniques. Results showed that edged plane pyrolytic graphite-single-walled carbon na...
The uptake and distribution of negatively charged superparamagnetic iron oxide (Fe₃O₄) nanoparticles (SPIONs) in mouse embryonic fibroblasts NIH3T3, and magnetic resonance imaging (MRI) signal influenced by SPIONs injected into experimental animals, were visualized and investigated. Cellular uptake and distribution of the SPIONs in NIH3T3 after staining with Prussian Blue were investigated by a...
PURPOSE To compare the cellular uptake efficiency and cytotoxicity of aminosilane (SiO(2)-NH(2))-coated superparamagnetic iron oxide (SPIO@SiO(2)-NH(2)) nanoparticles with three other types of SPIO nanoparticles coated with SiO(2) (SPIO@SiO(2)), dextran (SPIO@dextran), or bare SPIO in mammalian cell lines. MATERIALS AND METHODS Four types of monodispersed SPIO nanoparticles with a SPIO core s...
Prussian Blue (ferric hexacyanoferrate (II)), discovered accidentally in 1706 in Berlin by Johann Jacob Diesbach (1) and Johann Konrad Dippel (2), remains an intensively investigated material. Currently, more than 200 scientific publications with Prussian Blue as a research subject are published annually. Johann Leonhard Frisch (see below) and Diesbach produced Prussian Blue in the years follow...
Purpose: Human umbilical cord matrix (UCM) (Wharton jelly) stem cells labeling are tracking by MRI. Materials and Methods: After 48 hours incubation with USPIO human umbilical cord matrix (UCM) stem cells were labeled with USPIO by the means of receptor-mediated endocytosis. Prussian blue staining and Atomic absorption spectroscopy were performed to identify and show the iron oxide nanoparticle...
