Abstract

Plasmonic sensors are one of the most powerful optical biosensors, which can be used for the detection of small numbers of molecules at ultra-low concentrations. However, the detection of dilute analytes of low molecular weight (<500 >Da) is still a challenging task using currently available plasmonic biosensors. Here, we demonstrate the detection of both lower and heavier molecular weight biomolecules close to single molecule level using a novel plasmonic biosensor platform based on hyperbolic metamaterials. We show experimentally the extraordinary spectral and angular sensitivities of the biosensor platform, from visible to near infrared (NIR) wavelengths, by exciting the bulk plasmon polaritons associated with hyperbolic metamaterials.
