Visible Fluorescence Chemosensor for Saxitoxin [PDF]

open access: yesThe 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.
