Contamination of Hg2+ in an aqueous environment is dangerous for all living species including human. In this work, a new rhodamine B derivative fluorescent sensor (sensor RBS) for Hg2+ detection was successfully synthesized. In addition, the synthesized yellow silver nanoparticles (Y-AgNPs) were incorporated into sensor RBS to obtain sensor RBS+Y-AgNPs. The sensitivity studies for Hg2+ detection of...
A “naked-eye” indicator and fluorescent chemosensor based on fluorescein connected to two rhodamine B fluorophores by hydrazide moieties, RF1, was designed and synthesized for highly sensitive and selective detection of Hg 2+ . The sensor system operated through the FRET process from the fluorescein energy donor to the ring-opened rhodamine B acceptors. The binding to Hg 2+ was observed...
