In the previous study, we have reported the large scale fabrication of metal nanodome arrays exhibiting monochromatic plasmonic colors by using a bottom-up process, and the application for sensitive colorimetric biosensors. In this study, the size effect of metal nanodome structure on the detection sensitivity of plasmonic biosensor is investigated.
