Melamine-imprinted electrochemical sensor of graphene/ionic liquid composites and its use for the detection of melamine in dairy products
By exchanging the conventional role of functional monomer and template molecules, we develop a new molecularly imprinted nanospheres with grape grain structures based on multi-hydrogen bonding interactions between melamine and 6-aminouracil. Molecular imprinting-electrochemical sensor was establishe...

| description | By exchanging the conventional role of functional monomer and template molecules, we develop a new molecularly imprinted nanospheres with grape grain structures based on multi-hydrogen bonding interactions between melamine and 6-aminouracil. Molecular imprinting-electrochemical sensor was established with the assistance of graphene and ionic liquids. The content of melamine in dairy products was detected by the molecular imprinting-electrochemical sensor. The detection limit was determined to be as low as 1.57 × 10−3 mg kg-1. |
