Nano-Detection

Caption: Researchers illustrate the novel way they detected the BSA protein found in blood -- even smaller than a single cancer marker. As the BSA protein lands on the gold nanoshell that is attached to a microcavity, the bumpy gold sphere acts as a nano-amplifier of the interaction, leading to an enhanced shift in the cavity's resonance frequency. The charted waves show how the light wavelength shifts (red) once the BSA molecule lands on the nanoshell.
