We develop a new type of flexible nanohybrid microelectrode by decorating high dense PtAu alloy nanoflowers on 3D porous ionic liquid functionalized graphene wrapped activated carbon fiber. In virtue of the unique array of structural and chemical properties, the resultant hierarchical nanohybrid microelectrode exhibits a collection of good sensing performances, and can be used in near-cell sensitive detection of cancer biomarker secreted from different female cancer cells in normal state and treated by antitumor drug, which provides important information in distinguishing different cancer cells and normal cells and evaluating the therapeutic activity of antitumor drug towards the live cancer cells.
