Highly Conductive Peroxidase-like Ce-MoS₂ Nanoflowers for the Simultaneous Electrochemical Detection of Dopamine and Epinephrine.

ABSTRACT: The accurate and simultaneous detection of neurotransmitters, such as dopamine (DA) and epinephrine (EP), is of paramount importance in clinical diagnostic fields. Herein, we developed cerium-molybdenum disulfide nanoflowers (Ce-MoS₂ NFs) using a simple one-pot hydrothermal method and demonstrated that they are highly conductive and exhibit significant peroxidase-mimicking activity, which was applied for the simultaneous electrochemical detection of DA and EP. Ce-MoS₂ NFs showed a unique structure, comprising MoS₂ NFs with divalent Ce ions. This structural design imparted a significantly enlarged surface area of 220.5 m² g^-1 with abundant active sites as well as enhanced redox properties, facilitating electron transfer and peroxidase-l
