一种基于三苯胺-噻吩基团的新型荧光探针在藻细胞中检测CN‒的应用
A Novel Triphenylamine-thiophene Dyad Fluorescent Probe for Cyanide Detection in Living Algae Cells
摘要
Abstract
Cyanide(CN‒)is one of the most well-known toxic anions,some edible algae can release cyanide or absorb cyanide from their living environments,which may cause harm to human health.Therefore,we designed and synthesized a novel fluorescent probe TI for CN‒detection in living algae cells.Probe TI was constructed by triphenylamine-thiophene moiety and indolium moiety and exhibited remarkable blue fluorescence at 473 nm upon treatment with cyanide due to the nucleophilic attack of CN‒ on the C=N bond.Moreover,probe TI demonstrated excellent selectivity and sensitivity(LOD 95.7 nmol/L),and a fast responsive time for cyanide detection in an aqueous solution.Most importantly,probe TI could be applied for real-time detection of CN‒in living algae cells and edible algae.关键词
