Title

Responsive two-photon induced europium emission as fluorescent indicator for paralytic shellfish saxitoxin

Language

English

Abstract

A water-soluble europium(III) complex (1) has been synthesized and demonstrated to be a specific fluorescence probe for the paralytic shellfish toxin saxitoxin, a neurotoxin that blocks the voltage-gated sodium channels on cell membranes. Saxitoxin binds to the europium complex (KB= 6.1×104M-1) and triggers a two-photon induced f-f emission enhancement by over 100% and increases the two-photon absorption crosssection from 9 to 36 GM. © 2011 American Chemical Society.
