Abstract

The modified coffee-ring effect is used to self-assemble highly uniform, long-range-ordered Ag nanowire arrays. As the oriented Ag nanowire arrays provide excellent membranes for surface-enhanced Raman scattering, the molecular mechanism of cell adhesion and growth is systematically studied and well understood. This work has important significance for life science research.

Keywords: SERS; cell adhesion and growth; coffee-ring effect; nanowire arrays; self-assembly.
