▎ 摘　　要

NOVELTY - Preparing two-dimensional ferromagnetic nanocomposite sensing electrode, comprises peeling off the two-dimensional material, where the two-dimensional material is molybdenum disulfide, activated carbon, graphene, boron nitride, tungsten disulfide, or MXene materials, using the spinel-type magnetic material as a modifier and compositing the exfoliated two-dimensional material to prepare MMF nanocomposite, where the spinel magnetic material is MFe2O4, and M is manganese, cobalt, copper, magnesium, iron, and zinc, where the mass ratio of the two-dimensional material and the spinel magnetic material is 1:(0.3-1), dispersing the MMF nanocomposite in a mixed solution of ethanol/naphthol to form a suspension, and drying the suspension droplet on the clean electrode surface to form the nanocomposite sensing electrode. USE - The two-dimensional ferromagnetic nanocomposite sensing electrode is used to detect ascorbic acid, dopamine and uric acid individually or simultaneously (claimed). ADVANTAGE - The method is simple, the reaction condition is mild, the cost is controllable, the prepared electrode can detect ascorbic acid, dopamine and uric acid at the same time, and also can detect ascorbic acid, dopamine and uric acid in the presence of other interferents. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a nano two-dimensional ferromagnetic composite sensing electrode.
