Nanopillar Filters for Surface-Enhanced Raman Spectroscopy
We present a simple, robust, and automated molecule extraction technique based on a centrifugal microfluidic platform. Fast and facile extraction of a food adulterant (melamine) from a complex sample medium (milk) on a SERS substrate is demonstrated. The unique characteristic of the detection method is the obtained “filter paper/chromatographic” effect which combines centrifugal force and wetting properties of the SERS substrate.
The work addresses issues related to SERS-based detection of analytes in complex media, which is important for realizing next generation SERS platforms applicable for a broad variety of real-life applications.
