| Abstract |
Herein, we report a synthesis and application of magnetically-responsive and plasmonically-active gyro-nanodisks (GNDs) for Fourier transform surface plasmon resonance-based biodetection. These bifunctional GNDs were synthesized using electrochemical methods with anodized aluminum oxide (AAO) templates. Due to the unique properties of GNDs, periodic extinction signals were generated under an external rotating magnetic fields, which can be easily converted to frequency domains using Fourier-transform. After binding a target molecule on GNDs, an increase in the shear force causes a shift in the frequency domain, which allows us to investigate biodetection for HA1. Moreover, we achieved enhanced detection sensitivity by modulating the number and the location of plasmonic nanodisks. The concepts and approaches will contribute to further advanced sensing module performance, as well as a better understanding of dynamic nanoparticle system, by modulated periodic fluctuation of surface plasmon bands under the external magnetic fields. |
