本篇論文利用修飾不同分子的功能性金奈米粒子(Gold nanoparticles﹐AuNPs),藉由AuNPs本身具有高消光係數(Extinction coefficient)和特殊光學性質,開發出活性氧化物(Reactive oxygen species﹐ROS)與重金屬離子感測器。 一、以修飾異硫氰酸螢光素之金奈米粒子作為活性氧化物感測器—應用於血糖之偵測:本篇研究當中,我們利用修飾異硫氰酸螢光素之金奈米粒子(Fluorescein isothiocyanate-gold nanoparticles﹐FITC-AuNPs),可以簡單且靈敏地偵測ROS。當FITC螢光分子吸附在AuNPs表面,因為螢光共振轉移(Fluorescence resonance energy transfer﹐FRET)的原理,FITC分子的螢光訊號大部分都被AuNPs抑制。若我們把2-硫基乙醇(2-Mercaptoethanol﹐2-ME)加入到FITC-AuNPs中,原本吸附在AuNPs表面的FITC分子會被取代出來,而釋放到溶液中,使得螢光強度明顯增加。較為關鍵的是ROS可將兩個2-ME氧化成一個含雙硫鍵(Disulfide bond)的分子,而形成雙硫鍵的結構將無法取代出FITC分子,因此螢光訊號仍被抑制。綜合上述結果,當ROS含量越多,形成含有雙硫鍵的分子越多,而偵測到的螢光訊號相對越低,故可作為ROS感測器。對分析物ROS之最低可偵測濃度(Minimum detectable concentration﹐MDC)分別為:H2O2,1000 nM;超氧陰離子(Superoxide anion),600 nM;氫氧自由基(Hydroxyl radical)。基於此概念,我們開發出一套兩步驟的葡萄糖(Glucose)偵測法:首先,Glucose與其氧化酶(Glucose oxidase﹐GOx)進行反應將產生過氧化氫(Hydrogen peroxide﹐H2O2);接著,將所產生之H2O2與2-ME反應,再透過前面的方法,使用FITC-AuNPs進行偵測,對於Glucose之MDC為1000 nM。藉由本偵測系統亦成功偵測到血清中的Glucose。 二、利用修飾Tween 20界面活性劑之檸檬酸鈉金奈米粒子作為汞離子和銀離子感測器:在第二部分實驗中,我們利用修飾Tween 20界面活性劑之檸檬酸鈉金奈米粒子(Tween 20-citrate-gold nanoparticles﹐Tween 20-citrate-AuNPs),發展出一套快速且具有高選擇性的感測器,可以應用於定量分析Hg2+和Ag+。我們由實驗中發現,檸檬酸鈉包覆的金奈米粒子(Citrate-gold nanoparticles﹐Citrate-AuNPs)修飾上Tween 20界面活性劑,Tween 20分子只是穩固覆蓋在檸檬酸鈉分子上,並未將檸檬酸鈉取代出來。而使用Tween 20界面活性劑主要是保護Citrate-AuNPs可以穩定存在高離子強度溶液中,至於檸檬酸鈉分子是扮演還原劑角色,可將Hg2+或Ag+還原並於AuNPs表面形成金-汞合金(Au-Hg Alloys)或銀殼層(Ag Shell),導致Tween 20分子被迫脫離奈米粒子表面,如此AuNPs無法繼續穩定存在高離子強度溶液中而變為聚集狀態。本篇開發Tween 20-citrate-AuNPs感測器,使用氯化鈉(NaCl)和乙烯二胺四乙酸(Ethylenediaminetetraacetic acid﹐EDTA)分別作為偵測Hg2+和Ag+的遮蔽試劑(Masking agents),其MDC均可達100 nM。此外,使用本系統亦可偵測銀奈米粒子(Silver nanoparticles﹐AgNPs),其MDC為1 pM。據我們所知,本研究為首次利用同一種探針(Tween 20-citrate-AuNPs)即可同時偵測Hg2+和Ag+,並成功透過此系統分析飲用水中Hg2+、Ag+ 和AgNPs,以及海水中Hg2+。 |
