Bartos and M. Pesez. This article reveals the first ever prospective application of Graphene-Rhodamine array (GRH) as a colorimetric and fluorimetric sensor for Hg2+ ions. The duality of Graphene to undergo π–π and dispersive interactions with Rhodamine as well as to act as a selective adsorbent for Hg2+ is conceptualized in this study.

These interactions lead to decrease in absorbance of the dye in the Cited by: Jaroslav Bartos has written: 'Colorimetric and fluorimetric analysis of steroids' -- subject(s): Analysis, Colorimetric analysis, Fluorimetry, Steroids Asked in Authors, Poets, and Playwrights.

Steroids are divided into eight categories based on their structures and functions, and recent references using the above methodologies for the analysis of these steroids are cited. The synthesis and UV−vis and NMR spectroscopic studies of thiourea-based colorimetric sensors for anions are presented.

A rapid fluorescent probe based on the conjugate of chromone and benzothiazole moiety was presented, which could selectively respond to HSO3– over other common anions and thiols. The function of the probe relies on nucleophilic addition to break down the π-conjugation.

The probe can be used as a signal tool to determine HSO3– levels in sugar-based food and living by: 7.
