- Abstract
- A nanowire-mediated surface plasmon resonance
(SPR) imaging is numerically investigated for enhanced sensitivity.
The results calculated by rigorous coupled-wave analysis
present that interplays between localized surface plasmons and
surface plasmon polaritons contribute to sensitivity enhancement.
Compared to conventional thin film-based SPR imaging measurement,
an optimal nanowire structure can provide sensitivity
enhancement by 3.44 times as well as highly linear detection property
for quantification of surface reactions of interests. This paper
demonstrates the potential and limitation for a highly sensitive,
label-free, and real-time SPR imaging sensor based on periodic
metallic nanowires.
