Radioactive cesium (137Cs) has inevitably become a human concern due to exposure from nuclear power plants and nuclear accident releases. Many efforts have been focused on removing cesium and the remediation of the contaminated environment. In this study, we elucidated the ability of Prussian blue-coated magnetic nanoparticles to eliminate cesium from radioactive contaminated waste. Thus, the o...

Fig. 2. In vivo fluorescence images and MRI in prostate cancer bearing SCID mice. Upper panel: images acquired after nanoparticles injection. Lower panel: after co-injection of the compound and unlabele...

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...

As far as is known, the pigment Prussian blue was synthesised for the first time in Berlin in the early 1700s. It is commonly assumed that the pigment was not used in paintings before the 1720s. The presence or absence of this pigment is often used to answer questions concerning the dating and authenticity of art objects from the 18th Century. For the very first time, a large collection of Fren...

PURPOSE: Monitoring of stem cells migrating or homing to the targets is essential for the success of stem cell-based therapies. For non-invasive magnetic resonance imaging (MRI) to serially track cell migration, recent efforts have focused on labeling cells with MR contrast agents, such as superparamagnetic iron oxide (SPIO) particles. The currently-available MR cell labeling techniques include...

Prussian Blue (ferric hexacyanoferrate(II)) was discovered accidentally by Johann Jacob Diesbach (1) and Johann Konrad Dippel (2) in Berlin in 1706 (3). As the first synthetic pigment, Prussian Blue received its name from the country in which its discovery occurred. It revolutionized the use of the color blue in artwork because it was less expensive and/or more stable than other blue pigments o...

in this research, a fast colorimetric method for the detection of 4-phenylthiosemicarbazid (4-ptsc) in environmental samples, is reported for the first time. semicarbazide compounds have been used as pesticides or fungicides in agriculture and for chemical synthesis in industrial processes. with this method, one or the total amount of semicarbazide in real samples can be detected within 6-7 min...

BACKGROUND Multidrug resistance is the main obstacle to the efficiency of systemic chemotherapy against hematologic malignancy. This study investigated the reversible effect of the copolymer wogonin and daunorubicin coloaded into Fe(3)O(4) magnetic nanoparticles, and the mechanism potentially involved. METHODS The growth inhibition rate of K562/A02 cells was investigated by MTT assay, and apo...
