Optical Response Of Gold And Upconversion Nanoparticles Assembled Via Dna Interaction

In this paper we present an optical characterization of nanoparticle assemblies containing plasmonic gold nanoparticles and fluorescent upconversion nanoparticles in different ratios. Both the two-photon luminescence derived from gold nanoparticles and the fluorescence originated from upconversion nanoparticles are detected. The optical signatures reflect the composition of the assemblies.
