ABSTRACT:Recent progress in the fundamental understanding and nanofabrication of plasmonic nanostructures makes possible unparalleled advances in miniaturized, sensitive, label-free plasmonic biosensors. These promise to have a far reaching impact on point of care diagnostics where low cost and portability are important. While these emerging sensors possess great system simplicity and low cost, the greatest remaining challenge to being commercially viable is increasing the sensitivity. The sensitivities of nanoplasmonic sensors realized to date are 1-2 orders of magnitude lower than those for conventional surface plasmon resonance (SPR) systems. In this talk, a novel class of nanoplasmonic sensors will be introduced that combines plasmonic architectures with sensitive interferometric techniques. The resulting plasmonic interferometric biosensors exhibit ultrahigh sensitivities greater than 3600 nm/RIU and record high sensing figures of merit exceeding 200, greatly surpassing those of previous nanoplasmonic sensors and are comparable to commercial SPR systems. Real-time and sensitive multiplexed sensing will also be demonstrated based on our novel plasmonic interferometric sensors.
