초록

본 논문에서는 근접장-분자반응 간의 중첩을 이용한 표면 플라스몬 공명 (SPR) 바이오센서의 측정감도 평가방법을 연구하였다. 전달행렬 방법을 사용하여 다양한 형태의 중첩적분으로 정의된 광학자취 값을 계산하였고, 샌드위치 및 역샌드위치 면역글로뷸린 (IgG) 어세이에 대해서 실험적으로 측정된 수치와 비교하였다. 이론 및 실험적인 결과와의 비교를 통하여 접선 방향의 전기장을 사용한 광학자취의 경우 그 연속성으로 말미암아 가장 높은 상관계수를 얻을 수 있었으며 이때 광학자취와 측정감도 사이에 97% 이상의 높은 상관계수가 존재함을 보았다. 이러한 상관관계는 SPR 바이오센서의 측정 감도에 관한 메커니즘을 분명하게설명하며, 분자 스케일 감도를 가지는 SPR 바이오센서 개발에 기여하게 될 것이다.

Abstract

In this study, we have investigated the correlation of far-field detection sensitivity of surface plasmon resonance (SPR) biosensorswith optical signatures associated with the near-field overlap of biomolecules. The results confirm a direct relation between thefar-field and near-field parameters, particularly for optical signatures defined in terms of lateral electric field components that aretangential to the interface and thus continuous across the interface. The overall correlation between near-field optical signaturesand far-field resonance shift exceeded 97%. The results can be highly useful to evaluate detection sensitivity of SPR biosensorsthat take advantage of complex structures for localization of surface waves.
