On-Chip Colorimetric Detection of Cu^sup 2+^ Ions via Density-Controlled Plasmonic Core-Satellites Nanoassembly

We report on an on-chip colorimetric method for the detection and analysis of Cu2+ ions via the targeted assembly of plasmonic silver nanoparticles (2.6 nm satellites) on density-controlled plasmonic gold nanoparticles (50 nm cores) on a glass substrate. Without any ligand modification of the nanopa...
