＞奈米粒子感應器

過去所開發的奈米粒子感測器有下主要有兩種策略，首先係利用目標分析物導致金奈米子聚集，造成表面電漿共振波長紅位移，以聚集奈米粒子與分散奈米粒子消光的比率對目標分析物定量。此策略所開發的感測器如下：

(1) 透過控制金離子溶液的pH，可合成出粒徑分布較窄表面修飾上Gallic acid的金奈米粒子，除了可以窄化奈米粒子之粒徑分佈外，還可藉由比色法 (Colorimetric assay) 進行高靈敏度與高選擇性之 Pb2+ 偵測，本實驗室所開發之感測Pb(II)金奈米感測器，偵測極限可達10nM。

(2) 探討Mn2+於比色法，對表面吸附有單股寡核甘酸 Polythymine T33之金奈米粒子，與Hg2+進行雜交時的影響，發現可以有效改善比色法之靈敏度並加速其顏色的改變。

(3) Hg (II)與Ag (I)離子可於Tween 20修飾之金奈米粒子的表面沉積，移除穩定試劑Tween 20，進而導致奈米粒子聚集。利用此現象並加入適當遮蔽試劑可開發出感測Hg (II) Ag (I)離子之金奈米粒子感測器。

(4) 以 3-Mercaptopropionate acid 與 Adenosine monophosphate同時修飾於金奈米粒子上，於高鹽類下以吸收法檢測汞離子。

(5) 以 Human serum albumin 修飾的金奈米粒子，透過靜電荷吸引，選擇性偵測高 pI 之 Lysozyme，並且已成功應用於偵測雞蛋中的 Lysozyme。而第二類奈米感測器偵測策略係利用螢光分子吸附於金奈米粒子表面，因螢光共振轉移而導致螢光分子螢光消光。當目標分子出現取代螢光分子時，將使其螢光恢復。以上所敘述之奈米感測器其成果已發表於：

＞利用雷射脫附游離化質譜儀檢測生物分子

藉由檸檬酸修飾之金奈米粒子做為基質，以雷射脫附游離化質譜儀來偵測高鹽類溶液下之生物分子，例如：膽固醇類，以及真實樣品尿液中的尿素、肌酸酐、尿酸和葡萄糖等分析物。目前相關成果已發表於：

＞鐵奈米粒子合成與應用

我們發表一種簡單方法，僅需要利用共沉澱方式即可以一步合成poly (diallydimethylammonium chloride)(PDDA)修飾的 Fe3O4 NPs。此奈米粒子可透過靜電吸引力吸附glucose oxidase，形成一glucose oxidase 與 Fe3O4 NPs 的複合物；當加入 glucose 於此複合物時，glucose oxidase會催化glucose產生H2O2，此時溶液中2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonicacid) (ABTS) 會與H2O2反應，透過Fe3O4 NPs催化，氧化的 ABTS 在 420 nm有相當強吸收。此glucose oxidase與Fe3O4 NPs的複合物可重複偵測glucose，並且可應用於偵測血液中glucose。其成果已發表於：
