Research Abstract

We have succeeded in the preparation of plasmonic PS@Au nanoshells that resonates with the light of 600-1200nm and its surface. Further, controlling the nanoshell particle distance between adjacent provided the collective plasmon resonance mode . As a result, it has been able to 10fM level sensitivity. This value was of 1 million or more times higher sensitivity than that of conventional LSPR sensors. In this work, we tried to explore alternative materials to replace the gold is used for the shell, resulting pM level detection in the PS@Cu nanoshells array produced by coating a copper thin film.
