| Abstract |
Highly selective determination of dopamine (DA) over other catecholamines is an urgent need for the precise diagnosis and therapy of DA related diseases. Herein, a new formate-bridged Tb(III)-complex and silver nanoparticles (AgNPs) enhanced fluorescent nanosensor was constructed. HCOO-acted as a coligand of Tb(III) and also as a linker between the Tb(III) complex and AgNPs and more readily combined with the primary amine of DA than with epinephrine (EP). The formate-bridged action strengthened AgNPs-based surface enhanced fluorescence of the Tb3+-DA complex and improved the selectivity towards DA. Under neutral buffer conditions, the detection limit for the assay of DA was down to 0.15 nM (S/N = 3) with a linear range from 0.5 nM to 100 nM (R-2 = 0.9978). Furthermore, the nanosensor could successfully distinguish DA from EP. |
