Wettability read-out strategy for aptamer target binding based on a recognition/hydrophobic bilayer surface†
Abstract
We established a wettability read-out strategy for an aptasensor with a bilayer surface, using hydrophobicity reduction as the signal. The signal was induced by a fracture of the nanoneedle layer resulting from recognition by the supporting aptamer layer. The kinetics and influencing factors of this process were investigated with time curves.
