Abstract
Ultra-sensitive as well as on-site detections are strongly demanded in the field of detection technology, which can be achieved by μTAS utilizing surface enhanced Raman scattering (SERS). In this paper, we propose manufacturing of the SERS substrates with silver nano-particles utilizing the modified silver mirror reaction, where dispersants are added to the conventional silver mirror solution. The processes are very simple and completed in only 15 minutes at extremely low cost. The SERS substrate exerted extremely high Raman enhancement factor of 106. We fabricated a μTAS device containing the SERS site. It successfully showed remarkably high Raman enhancement with good repeatability. The fabricated SERS substrate and μTAS device herein are low cost and exhibit good repeatability and thus, are readily applicable to ultra-sensitive and on-site detections in various applications.
