A sensitive fluorescent analytical method for the detection of dopamine (DA) was developed based on surface-enhanced Tb(III)/La(III) co-luminescence using silver nanoflowers (AgNFs). Anisotropic AgNFs show strong surface-enhanced fluorescence effect owing to the abundant sharp tips. Tb(III)/La(III)-DA complexes mainly bind to the sharp tips of AgNFs and thus shorten the distance between the complexes...
Dopamine (DA) is one of catecholamines and related to several neurological diseases. The selective determination for DA against other catecholamines is crucial in clinical diagnoses. In this work, a simple and reliable Tb(III)-based fluorescence sensor was constructed for the highly selective and sensitive detection of DA. Silver nanoprisms (AgNPrs) with suitable localized surface plasmon resonance...
