Non‐enzymatic electrochemical detection of dopamine in blood serum based on porous nitrogen‐doped graphene/Fe ₃ O ₄ nanocomposites

Facile Synthesis of Hollow Fe3O4-rGO Nanocomposites for the Electrochemical Detection of Acetaminophen

“…More recently, magnetic Fe 3 O 4 nanoparticles have shown excellent magnetic properties, electrical conductivity, chemical stability, biocompatibility, and low toxicity. Therefore, Fe 3 O 4 nanoparticles have received increasing attention as potential electrode modification materials or have been widely applied in electrochemical sensors and biosensors [ 22 , 23 , 24 , 25 ]. In addition, magnetic Fe 3 O 4 nanoparticles with hollow structures can provide a larger electrochemically active area [ 26 , 27 ].…”

Electrochemical Detection of Dopamine Release from Living Neurons Using Graphene Oxide‐Incorporated Polypyrrole/Gold Nanocluster Hybrid Nanopattern Arrays

“…[32][33][34][35][36][37][38][39] However, most DA sensors reported previously targeted the DA in blood for the early diagnosis and progression of PD. [40][41][42][43][44] In this case, the interfering materials are mostly biomolecules that are abundant in the human plasma, including ascorbic acid, uric acid, and hormones. For the selective detection of DA release from neuronal cells, the materials and structures used for the electrode modification should be differently tuned because of the structural similarity of DA with other neurotransmitters (e.g., levodopa (L-DOPA), tyrosine, epinephrine, and norepinephrine).…”
