Electrochemical Tape-and-Paper-Based Sensor for the Quantification of Potassium
… or even home-use. Our sensing method relies on Prussian blue immobilized on the surface of electrodes as a potassium recognition element. Potassium ions intercalate into the Prussian blue lattice and subsequently changes the electrochemical characteristics of Prussian blue such as the redox peak …

Micro-fading spectrometry: an ivestigation into display of traditional watercolour pigment in anoxia
… fading and reversion behaviour of a traditional Prussian blue pigment ground in gum Arabic was investigated for the first time in 0%, 2%, 3.5%, 5%, 10% or 21% oxygen concentrations. Results from this investigation indicated that the previously reported deleterious effects of reduced oxygen …

Methods to detect and quantitate spleen added to ground beef
… maintained a white to grey-white color after Prussian blue iron staining. Pellets from spleen-added samples developed a blue color. The amount and intensity of blue increased as the amount of spleen in the product increased. A presumptive test was performed by applying Prussian blue directly …

Electrochemically generating electric field gradients in the absence of buffer for membrane-free separations
… reduction of the intercalation material Prussian blue within a microfluidic device. The results showed that the reduction of Prussian blue and concomitant ion intercalation from solution selectively formed an ion depletion zone and corresponding electric field gradient. This electric …

The Reeves Collection: An Investigation into Chinese Botanical Drawings, Their Identification and Conservation
… and western papers, but with the addition of Prussian blue. New evidence for the Chinese manufacture of this colour is presented. A Chinese method of lead white reversal proved unsatisfactory. WS-EHEC and funori were identified as the most appropriate consolidants for future testing. The wider …

Cytochrome C biosensor for the determination of trace level arsenic and cyanide compounds
… immobilised and used for direct determination of Prussian blue, potassium cyanide and arsenic trioxide by inhibition mechanism. The sensitivity as calculated from cyclic voltammetry (CV) and square wave voltammetry (SWV), for each analyte in phosphate buffer (pH= 7) was found to be (1.087- 4.488 …

Molecular-based magnets constructed from cyanometalate building blocks
Solids related to Prussian blue (FeII,3lFen(CN)6]2,JcH20) are shown to be ideal candidates for the preparation of molecular-based magnets with high magnetic ordering temperatures: they can be easily prepared from well-characterized cyanometalate building blocks, the metal centers are linked …

Fabrication, characterization, and optimization of porous electrodes for electrochemical desalination
… Faradaic electrodes, such as those composed of Prussian blue analogues (PBAs), having high ion storage capacity. However, when compared with desalination technologies such as reverse osmosis, FDI is currently limited by impractically high energy consumption and low salt removal. The work in this …

Ferritin: Mechanistic Studies and Electron Transfer Properties
… Iron transfer is studied by the formation of Prussian blue ([FeIIFeIII(CN)6]-) encapsulated in the ferritin cavity, and is consistent with a binding-dissociation model proposed previously for iron transfer through the three-fold channels. When native HoSF is reduced by methyl viologen in …
