Victoria Pure Blue BO is a dye that bears some therapeutic activity and can be retrieved in effluent or may used aquaculture as prohibited drug. In this study, the metabolism tissue distribution during uptake depuration of VPBO were investigated order to propose residue marker illegal treatment fish. The was administered rainbow trout (oncorhynchus mykiss) for one day by water bath at dose 0.1 ...

The aim of this work was the design, synthesis, and characterization new chromogenic spirolactone dyes based on a 2-phenyl-1-benzopyrylium (flavylium) backbone for further development thermochromic smart labels. influence electron-donating electron-withdrawing groups five synthesized studied in terms color modification, acid-base behavior properties. By using UV–Vis absorption emission spectros...

Thermal paper finds its extensive use in the modern day life and could act as a vital piece of physical evidence carrying latent fingermarks. A large number of citations are available in literature suggesting various techniques to develop these marks but all are suffering with one or the other drawbacks such as complex and cumbersome procedure, pre- or post-treatment, background coloration and ...
