title: 3,4,9,10-Perylenetetracarboxylic acid/o-phenylenediamine nanomaterials as novel redox probes for electrochemical aptasensor systems based on an Fe3O4 magnetic bead as a nonenzymatic catalyst.
abstract: A novel redox probe 3,4,9,10-perylenetetracarboxylic acid/o-phenylenediamine (PTCA/OPD) with well-defined redox peaks caused by the synergistic action between them was demonstrated via theoretical and practical research, and applied in an electrochemical aptasensor to detect thrombin (TB) based on an Fe3O4 magnetic bead (MB) as a nonenzymatic catalyst.
