Aggregation of Au Colloids using Surface Acoustic Waves

Aggregation of Au Colloids using Surface Acoustic Waves

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, indicati...

Zusammenfassung: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.
