  • Title: Nanopillar Filters for Surface-Enhanced Raman Spectroscopy.
    Author: Durucan O, Rindzevicius T, Schmidt MS, Matteucci M, Boisen A.
    Journal: ACS Sens; 2017 Oct 27; 2(10):1400-1404. PubMed ID: 28956441.
    Abstract:
    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.
