Prussian blue nanoparticles (PBNPs) with controlled nano-geometry were synthesized from a single precursor (potassium hexacyanoferrate) in the presence of three different reagents, namely, polyethylenimine (PEI), tetrahydrofuran (THF)/H 2 O , and 2-(3,4-epoxycyclohexyl)-ethyl-trimethoxysilane (EETMS)/cyclohexanone, which enabled nucleation stabilization PBNPs variable plasmonic activities for s...

INTRODUCTION Many investigators report that Prussian blue is effective on removing radiocesium from the body. However, we does not agree with the results obtained from the animal experiments, because administration methods on Prussian Blue administration used in these experiments, e.g., dose, route, initial time, resulting in superior effects are marked different from the conditions in the huma...

The recent progress in application of nanostructures in electrochromic materials and devices is reviewed. ZnO nanowire array modified by viologen and WO₃, crystalline WO₃ nanoparticles and nanorods, mesoporous WO₃ and TiO₂, poly(3,4-ethylenedioxythiophene) nanotubes, Prussian blue nanoinks and nanostructures in switchable mirrors are reviewed. The electrochromic properties were significantly en...

Figure 2: The spin-echo image of the tumor shows the inhomogeneous enhancement of the tumor tissue (A) and the adiabatic contrast image shows a region of enhancement with suppression of the PBS and tumor (B). Histological examination of this section with Prussian Blue staining shows the presence of SPIO (C) in this region highlighted in (A) by a green oval. Characterization of Adiabatic Pulse P...

Specific targeting is a key step to realize the full potential of iron oxide nanoparticles in biomedical applications, especially tumor-associated diagnosis and therapy. Here, we developed anti-GD2 antibody conjugated iron oxide nanoparticles for highly efficient neuroblastoma cell targeting. The antibody conjugation was achieved through an easy, linker-free method based on catechol reactions. ...

The dissociation of apoferritin into subunits at pH 2 followed by its re-formation at pH 8.5 in the presence of hexacyanoferrate(III) gave rise to a solution containing hexacyanoferrate(III) trapped within the apoferritin and hexacyanoferrate(III) outside it. The addition of Fe(II) to the dialyzed solution resulted in the appearance of the characteristic Prussian blue color. The UV-vis spectrum...

CONTEXT Prussian blue, ferric hexacyanoferrate is approved for (oral) treatment of internal contamination with radioisotopes of cesium or thallium. Cyanide makes up 35-40% of Prussian blue's molecular composition; thus, cyanide may be released during transit through the digestive tract under physiological pH conditions. OBJECTIVES The purpose of this study is to assess the long-term stability...

Objective To preliminarily evaluate technical feasibility of a dual-echo ultrashort echo time (UTE) subtraction MR imaging by using concurrent dephasing and excitation (CODE) sequence for visualization of iron-oxide enhancement in focal inflammatory pulmonary lesions. Materials and Methods A UTE pulmonary MR imaging before and after the injection of clinically usable superparamagnetic iron-ox...
