Pagoda-like nanopillar arrays are created by employing standing wave during phase-shift interference lithography. The series of metallic nanogaps on the side walls of nanopillars provide high density of hot spots for localization of electric field, thereby serving as effective SERS substrate. Moreover, the arrays can be further micropattened by photolithography, enabling analysis of multiple samples on a single substrate.
