Abstract
On-chip integration of plasmonics and dielectrophoresis can provide a promising route towards multi-functional biosensors. Here we present a novel 10-nm-split-trench resonator that combines a high-Q resonant plasmonic biosensor with gold nanogap electrodes. The electrically biased trench resonator can attract or repel analytes via dielectrophoretic forces created from a 10-nm gap while detecting them in a label-free manner via surface plasmon fields inside the trench. As a result, the plasmonic electronic biosensor enables the dynamic and low-voltage detection of nanoparticles and proteins at low concentrations.
