Self-assembly of thiolated cyanine aggregates on Au(111) and Au nanoparticle surfaces

Mostrar todas las versiones(2)

Heptamethinecyanine J-aggregates display sharp, intense fluorescence emission making them attractive candidates for developing a variety of chem-bio-sensing applications. They have been immobilized on planar thiol-covered Au surfaces and thiol-capped Au nanoparticles by weak molecular interactions....
