Thiol Reactive Probes and Chemosensors [PDF]
Sensors, 2012 Thiols are important molecules in the environment and in biological processes. Cysteine (Cys), homocysteine (Hcy), glutathione (GSH) and hydrogen sulfide (H2S) 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

Visible Fluorescence Chemosensor for Saxitoxin [PDF]
The Journal of Organic Chemistry, 2007 Absorption spectra of a number of shellfish extracts have been obtained and reveal prominent absorptions in all samples at 210 and 260 nm and at 325 nm in some of them. These absorptions preclude the use of chromophores with similar absorptions in testing of shellfish samples for paralytic shellfish toxins.
