Self-assembly-based integration of Ag@Au oligomers and core/shell nanoparticles on polymer chips for efficient sensing devices

Autor: Abeer Fahes, Aotmane En Naciri, Mohamad Baker Shoker, Suzanna Akil

Publikováno v: Soft matter.

Two distinct Ag/Au nanocomposites, namely, hetero-oligomers and eccentric core/shells were obtained by one-step polymer self-assembly-based fabrication. The Ag concentration-dependent, facet-specific passivation, and presence or absence of anisotropi
