摘要

Dopamine is a kind of neurotransmitter. The abnormalities in dopamine metabolism may lead to various psychiatric and neurodegenerative diseases. Thus, fast and accurate detection of dopamine is urgently needed. Presented in this Letter is a convenient and cost-effective electrochemical method for the detection of dopamine based on aptamer and graphene. The specific recognition between dopamine and...
