BPN381: SERS Signal Amplification by Optofluidic Photothermal Sample Preconcentration

Project ID BPN381

Start Date Fri 2007-Jan-26 13:00:18

Abstract integrated microfluidic devices. Preconcentration not only improves detection sensitivity of SERS signals but also improves the reliability of the analysis by significantly increasing signal-to-noise ratio. Another reason necessitating preconcentration is the discrepancy between volumes of sample available and those consumed for analysis. The general goal is to preconcentrate a molecule based on thermophoresis in a microfluidic platform to amplify the SERS signals. Our first specific goal is to preconcentrate target molecules using and the second goal is to amplify the SERS signal of preconcentrated molecules.
