Methylene blue dye

A similar technique has been applied to the generation of monodisperse suspensions in water. This type of method was first used in medical field and then widely used to spray monodisperse solid particles such as polystyrene latex particles. Aerosols of solutes have also been produced by atomizing solutions of salt, sugar or methylene blue dye dissolved in water. In practical operations, a low concentration of solid particles in a solvent is recommended in order to avoid possible agglomeration of suspensions in the solvent. 

The EMM technology has been widely tested in both animals and humans and has an excellent safety profile [26, 124-130]. Kornowski et al. [128] have studied the dynamics of transendocardial delivery using different needle extensions to inject 0.1 cc of methylene blue dye as a tracer. A total of 152 injections were performed with needle... 

Effect of 100 pM methylene blue dye on bubble production in agarose gels (0.2% w/w, 0.27 ml) containing distilled water and pH 5.0 (1 mM NaHC03) buffer. (Taken from ref. 231.)... 

The cell concentration was determined by microscopic counting (Olympus B-201) in a Biirker-type chamber on five beads dissolved in 10 mL of 1% sodium citrate solution and shaken for 10 min at 30°C. Although this method gives the total number of cells (dead and live), methylene blue dyeing revealed that most of the cells were alive. 

Fig. 5. Filtration of the white blood cells from diluted human whole blood using a comb-type filter chip. The white blood cells were stained with New Methylene Blue dye. The image was taken by reversing the applied pressure slightly to allow the trapped white cells be released from the front surface of the filters (arrow) and be seen clearly [3]...

Fig. 6. Filtration of the white blood cells from New Methylene Blue dye stained undiluted human whole blood using a weir-type filter chip (flows direction is indicated by the arrow). The image was taken during the filtration process. The purple-blue particles seen in the middle of the chip were the stained white cells trapped on the surface of the weir filter...

The test is based on the adsorption principle of clay minerals using methylene blue dye. During the test, the quantity of methylene blue required to cover all clayey ingredients is measured. The quantity of methylene blue dye adsorbed is related to the specific surface of the clay mineral (montmorillonite, illite and kaolinite). Active clay minerals have a large specific surface in contrast to inactive clay materials. As a result, the required methylene blue quantity will be proportional to the quantity and the type of clay minerals. 

Methylene blue dye has an adsorbed area per molecule of 1.75 run cm. A 100 ml aqueous solution of dye has an optical density (absorbance) of 0.65 at a certain wavelength. After the solution is equilibrated with 25 mg of an activated carbon, the supernatant solution is found to have an absorbance of 0.20. Estimate the specific surface area of the carbon. 

There are also compositions that function primarily in visible light. An example is diphenyliodonium salt or methylene blue dye in combination with triphenyl alkyl borate complexes. They were found to be effective with light in the visible spectrum." In addition, titanocene derivatives will photolize directly... 

Also, nanomodified ZnO is found to improve photocatalytic properties compared to micro-sized ZnO. Sebastian et al showed that the intensity of blue colour of methylene blue dye reduced at a faster rate in presence of nano-ZnO due to the enhanced rate of photo decomposition of the dye.
