“…And, the signal is disturbed by the large noise effect. To solve these problems, we focused on SERS (Surface Enhanced Raman Scattering) [5][6][7][8][9][10][11][12][13][14][15][16]. SERS is an analytical method that does not require antibody labeling or device limitations due to optical path length.…”

For the implementation of SERS in microfluidic devices, we propose a rotor structure using SAW as a simple aggregation mechanism. In this study, 45 nm gold nanoparticles were agglomerated in a rotor and evaluated. It was found that the aggregate size increased with increasing supply energy, indicating that this mechanism contributes to aggregate formation. SERS measurements using this mechanism were also successfully performed.
