中文摘要

本研究提出一新型三紙張分析平台應用於免疫檢測，可以透過簡單蠟製程及摺疊紙張之方式完成平台製作。檢測設計以直流式免疫分析法達到縮減流體路徑以減少無效體積的目的，並且結合滑動紙張之設計減少使用者操作步驟。本平台整體全部由層析紙構成，為了達到抗體以穩定共價鍵結方式固定在紙張表面，吾人於偵測區域進行羧甲基纖維素（carboxymethyl cellulose, CMC）與1－（3－二甲氨基丙基）－3－乙基碳二亞胺鹽酸鹽（N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride, EDC）／N－羥基丁二醯胺（N-hydroxysuccinimde, NHS）紙張表面處理，以取代昂貴的硝化纖維膜，提升平台的專一性。此外，本研究將抗體加入蔗糖與海藻糖作為穩定劑並以冷凍乾燥方式保存於層析紙上，增加平台的可攜性及延長抗體的有效期限。經實驗結果證實本平台進行人類免疫球蛋白G測試，僅需3 μL樣品即可獲得偵測極限為0.1 ng/mL，並可在7分鐘內得知檢測結果，此檢測裝置可在冷藏4°C下長效保存75天，達到製程簡單、操作步驟簡易、所需樣品量少、具靈敏度、檢測時間短之快速篩檢的目的，可預期此研究將來可簡單擴充至其他疾病檢測。
英文摘要

We successfully demonstrate a novel three-dimesnional (3D) origami paper-based analytical device (oPAD) for immunoassay applications. By combining surface modification of the cellulose paper and the slip design, users can easily perform immunoassay in rapid and stable manners. Costly nitrocellulose membrane for affinity biorecognition molecules covalently conjugated is replaced using carboxymethyl cellulose (CMC), N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride (EDC)/N-hydroxysuccinimde (NHS) modified cellulose paper. In addition, biorecognition molecules are lyophilized to extend the lifetime and portability of the device during storage and transportation. The results showed that anti-human immunoglobulin G (IgG) conjugates horseradish peroxidase (HRP) dried in a variety of sugar matrices retained 80% of their activity after 75 days of storage at 4°C. The detection limit of 3D origami paper-based analytical device for human IgG is 0.1 ng/mL, and the assay results could be visualized in 7 min.
