Abstract:
Biosensing is currently a growing research field which is relevant for different applications, for instance in health care. Sensitive and cheap biosensors are required, preferably as simple as possible in their working principle. In this work Si nanopillar structures have been fabricated and used to show the sensing principle by both depositing oxide layers with different thicknesses and by using the biotinstreptavidin model system. Si nanopillars were fabricated by two different surface patterning methods – colloidal lithography and nanoimprint lithography (obtained from a commercial source).

Specific detection of biological matter is one of the key elements in a wide range of modern fields such as food industry, medicine, environmental and pharmaceutical industries.

All of the above issues result in high costs for biological analysis, and consequently, high costs for medical service, therapeutic drugs and various food products.

Abstract:
由於表面等離子體激元可以將電磁場限制在金屬表面，從而產生強烈的場強增強效果，因此在納米光子學和生物光子學方面具有廣泛的應用價值，其中包括高性能發光二級管、光伏電池、超高分辨率光學成像和超靈敏分子檢測等。尤其在單分子和醫學診斷方面，基於表面等離子體共振的生物傳感器獲得了越來越多的青睞。本論文包括兩部份。第一部份著重討論二維週期性洞陣列的表面等離子體特性，而第二部份則是研究這種洞陣列結構在表面等離子體共振傳感方面的應用。<br>在第一部份中，表面等離子體模式被分為非簡並模式(m，O) 和簡並模式(m，±n)兩種情況分別加以討論。首先，結合實驗結果和理論模型，我們對非簡並模式的衰減壽命和激發效率進行了研究。通過光干涉光刻法和薄膜沉積技術，一系列不同幾何結構的洞陣列樣品被製備出來，且這些樣品具有很高的重複性。利用角分辨色散關係進行模式識別以及確定這些模式的衰減壽命和激發效率。通過調整起偏器和檢偏器的相對方向，表面等離子體模式的非輻射和輻射衰竭均可加以研究。結果發現，衰減壽命強烈依賴於單洞的幾何結構，而且這種行為可以用簡單的靜電模型并考慮高階修正加以解釋。從非輻射衰減和輻射衰減平衡的角度出發，激發效率對幾何結構和共振波長的依賴性也可以理解。對於簡并模式，由於存在稱合，對稱模式和反對稱模式分別被p 偏振激發和S偏振激發。它們的對稱性和對於衰減壽命和共振波長的修正可以用干涉法和模式耦合理論來理解

博士<br>國立臺灣大學<br>光電工程學研究所<br>96<br>In this dissertation, a detailed study of the optical properties of single metallic nanoslit and multiple metallic nanoslits is presented. In experiment, high sensitive, label-free, high-throughput, reusable, and chip-based biosensor arrays based on surface and gap plasmon resonance were fabricated and tested. In the study of optical properties of metallic nanostructures, metallic nanoslits with periods varying from 400 to 900 nm and widths ranging from 20 to 200 nm were fabricated on a thin gold film using e-beam lithography and reactive ion etching.

碩士<br>國立臺北科技大學<br>光電工程系研究所<br>97<br>In this dissertation, we present an electro-optically modulated localized surface plasmon resonance biosensing system in the attenuated-total-reflection configuration, which can be used to measure the concentration of biochemical material. The sensing chip consists of a sensing region and one pair of electrodes on the ridge structure. When the voltage is applied on the electrodes, the electric field produced in lithium niobate electro-optically modulates the refraction index and changes the wave vector of the incidence lightwave. In this study, we use two ki
