Title:
DOPAMINE DETECTION APPARATUS AND MANUFACTURING METHOD FOR DOPAMINE DETECTION ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2023/004873
Kind Code:
A1
Abstract:
A dopamine detection apparatus, a surface of a glassy carbon electrode being modified using a reduced graphene oxide-Co3O4-metal nanocomposite material. A manufacturing method for a dopamine detection electrode, comprising the following steps: synthesizing graphene oxide (S10); preparing a reduced graphene oxide-Co3O4 composite material (S11); depositing metal nanoparticles on the reduced graphene oxide-Co3O4 composite material to obtain a reduced graphene oxide-Co3O4-metal nanocomposite material (S12); polishing a surface of a glassy carbon electrode (S13); and modifying the reduced graphene oxide-Co3O4-metal nanocomposite material on the surface of the glassy carbon electrode (S14). It is proposed that a ternary nanocomposite material of rGO, Co3O4 and metal can be used as a coherent platform for glassy carbon and screen-printing electrode modification. rGO may provide a supportive and electrically conductive platform for Co3O4 nanoparticles. A functional group on rGO will help to improve selectivity and dispersibility in polar solvents. Co3O4 will act as a catalyst for DA oxidation, while a precious metal will catalyze oxidation by promoting charge transfer.
