Fluorescence chemosensors for selective sensing and quantification of biologically important metal ions have attracted substantial research focus in recent years. Cu(II) is the third most abundant transition ion and...

Thiols are important molecules in the environment and in biological processes. Cysteine (Cys), homocysteine (Hcy), glutathione (GSH) and hydrogen sulfide (H(2)S) play critical roles in a variety of physiological and pathological processes. The selective detection of thiols using reaction-based probes and sensors is very important in basic research and in disease diagnosis. This review focuses o...

A library of bis[zinc(II)dipicolylamine]-functionalised linear peptides was prepared using an efficient solid phase peptide synthesis approach and their use as chemosensors for anions in water was investigated using indicator displacement assays. High affinity and selectivity for pyrophosphate (PPi) over adenosine triphosphate (ATP) and adenosine diphosphate (ADP) were observed and additional a...

Differential chemosensors have emerged as next-generation systems due to their simplicity and favourable responsive properties produce different signals upon selective binding of various analytes simultaneously. Nevertheless, given inadequate fluorescence response laborious synthetic procedures, only a few differential been developed so far. In this work, we employed single pot synthesis strate...

Ratiometric fluorescent chemosensors 1 and 2 were synthesized based on tyrosine amino acid derivatives with a pyrene fluorophore. 1 and 2 showed high selectivity for Hg(II) ions among 13 metal ions in aqueous solutions. Both 1 and 2 sensitively detected Hg(II) ions in aqueous solutions by ratiometric response without interference of any of the other tested metal ions including Cu(II), Cd(II), P...
