An “off–on–off” fluorescence chemosensor for the sensitive detection of Cu2+ in aqueous solution based on multiple fluorescence emission mechanisms

A new type of fluorescent chemical sensor (AHBH-PMOs) with AIE and ICT mechanisms is synthesized, which can detect copper ions in pure aqueous solution with good selectivity and high sensitivity.

Anionic metal–organic framework as a unique turn-on fluorescent chemical sensor for ultra-sensitive detection of antibiotics

Fabrication and engineering of an anionic metal–organic framework as a unique turn-on fluorescent chemical sensor for the ultra-sensitive detection of antibiotics.

A selective and sensitive peptide-based fluorescent chemical DSH sensor for detection of zinc ions and application in vitro and in vivo

Here we report the design and synthesis of a peptide-based fluorescent chemical sensor (DSH sensor: Dansyl-Ser-Pro-Gly-His-Trp-Gly) for detecting Zn2+, based on fluorescence resonance energy transfer (FRET) from tryptophan (donor) to the dansyl fluorophore (acceptor).
