文摘

A type of plasmonic Ag@Si chips composing of Si supported Ag film was fabricated. The chips show viable integration into fluorescent immunoassays for enhancement. The chips show up to 57 times enhancement at 800 nm in fluorescence protein assay. The chips show up to 4.1 times fluorescence enhancement for cell and tissue imaging.
