Investigation of the profile effect on the sensitivity enhancement of nanowire-mediated localized surface plasmon resonance biosensors

  title={Investigation of the profile effect on the sensitivity enhancement of nanowire-mediated localized surface plasmon resonance biosensors},
  author={Kyung Min Byun and Donghyun Kim and Sung June Kim},
Localized surface plasmon resonance (SPR) biosensors with metallic nanowires regularly patterned on a gold film are considered for sensitivity nhancement. The theoretical investigation was conducted using rigorous coupled wave analysis in terms of various design metrics, such as the esonance angle shift, the SPR curve angular width, and the minimum reflectance at resonance. The results show that nanowires of a T-profile resent more effective sensitivity enhancement than an inverse T-profile… CONTINUE READING
