The molecular association through host-guest interaction of chromophoric dyes having technological and biological importance have been investigated with a macrocyclic receptor, cucurbit[7]uril (CB7). Exploiting host-guest (CB7rhodamine 6G) interaction, the construction of a highly efficient “water-based supramolecular dye laser” has been demonstrated. The CB7 imposed modulation of the protonati...

Azo, anthroquinone and triphenylmethane dyes are the major classes of synthetic colourants, which are difficult to degrade and have received considerable attention. Congo red, a diazo dye, is considered as a xenobiotic compound, and is recalcitrant to biodegradative processes. Nevertheless, during the last few years it has been demonstrated that several fungi, under certain environmental condit...

Drug residues are considered environmental contaminants, and their occurrence has recently become a matter of concern. Analytical methods and monitoring systems are therefore required to control the continuous input of these drug residues into the environment. This article presents a suitable HPLC-ESI-MS/MS method for the simultaneous extraction, detection and quantification of residues of 13 d...

A quantitative and confirmatory method for detecting the presence of triphenylmethane dyes in shrimp muscle using ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) a quick, easy, cheap, effective, rugged safe (QuEChERS) extraction approach was validated. The exhibited linearity selectivity coefficient determination (R2) higher than 0.95 all studied analytes. Li...
