SIMs-Arg and SIMs-Lys were prepared via surface fragment imprinting technique.
SIMs-Arg and SIMs-Lys possessed a desired magnetic susceptibility and reusability.
SIMs-Arg and SIMs-Lys had high specific adsorption property for TP5 in real sample.
The portion of target which is selected as template is vital in fragment imprinting.
The imprinting approach provides a new opportunity for biomolecules imprinting.
