Description

200530582 ' ' (1) 、 : 九、發明說明 【發明所屬之技術領域】 本發明係關於生物感知器及其於偵測流體中的電解質 方面之使用。 【先前技術】 以前的技術包括用以測定流體中之電解質量的試條’ > 包括電化學生物感知試條。 這樣的試條特別用以測體人體血液中的葡萄糖。這樣 的試條可供糖尿病患者及保健從業者來偵測其血液中的葡 萄糖量。此試條被設計用於染料的光偵測時’此試條常與 測定光反射値的儀表倂用,或者,設計用以偵測電活性化 合物時,其可用以測定一些電力性質(如:電流)° 但是,個人使用者使用以前製造的試條有一些問題存 在。例如,試條相當小,視力受損的糖尿病患者將血液樣 | 品適當地加至試條的樣品添加區域中有很大的困難。將試 條製成視力受損者容易將樣品添加在試條上者有其效用。 試條是毛細管充塡設計時,當試條的化學反應區是一 個毛細空間時,平順地及足量地以欲測試的樣品塡充此區 時會發生特別的問題。因爲毛細空間和用以製造試條的材 料組成少,試驗樣品進入毛細管反應區中時可能會停頓。 此外,引至毛細管反應區中的樣品量可能會不足,因此會 產生不正確的測試結果。若能儘量減少這樣的問題將會非 常有用。 -5- 200530582 (2) 、 最後,大量製造試條,特別是糖尿病患者用以測試的 血液葡萄糖量用的試條。用以製造這些試條的方法(如: 機械打孔)可能會使試劑在測試區域表面上而乾掉破裂或 破碎,因此造成試劑損失或試劑未能位於試條的適當位置 上。設計使得測試試劑能夠忍受加工步驟(如:機械打孔 )也會非常有用。 本發明的電化學生物感知試條提出解決以前的試條的 > 這些前述問題的方法。 【發明內容】 本發明是一種改良之電化學生物感知試條,其有四個 新穎且非常有利的特點。 第一個新的特點是:順著試條的一邊有凹痕狀,容易 辨視樣品施用點,以便於視力受損的人或於無亮光或光亮 條件欠佳時使用。 g 此試條具有毛細測試區,測試區頂部包括此生物感知 試條的第二個新特點。此第二個新特點是一種透明或半透 明視窗,以''充塡於此處〃線的方式操作,藉此辨別是否 有足量的測試樣品(液體樣品,如:血)被加至此測試區 中,以準確地進行測試。此視窗定出準確測試所須的最少 樣品量,因此,降低因爲在試條上的施用量不足而造成誤 判的可能性。 視窗的長和寬比毛細測試區的長和寬來得短。視窗的 尺寸和位置使其覆於生物感知試條之工作電極的整個寬度 -6- 200530582 , Ο) . ° 上及覆於平衡或參考電極的至少約i 〇 %寬度上。較佳情況 中,環繞視窗的頂部區域被著色,使得使用者在透過視窗 觀察時,樣品有良好的顏色對比性,且頂部區域環繞著視 窗以便於辨認試條的足夠添加量。 此試條的第三個新特點是在樣品施用區處有一或多個 缺口。在第一個隔絕底質和試條頂部都有一個缺口。這些 缺口的尺寸和位置使得它們在試條中互相交疊。這些缺口 減少所謂的 ''施用遲疑〃。樣品加至無缺口試條的樣品施 用區時,樣品進入毛細測試區時會有停頓的情況。此 ''施 用遲疑〃會延長測試時間。試條包括缺口時,施用遲疑情 況減少。此外,在第一個絕緣底質和頂部皆有缺口者,使 得試樣能能夠以寬變化角度朝樣品施用區前進。若只有頂 部有缺口,此試樣的前進角度受到的限制會比較大。 最後,此試條的第四個新特點是試劑包括平均分子量 約1 00,000道耳吞至約900,000道耳呑、濃度由約0.2% ( & 重量:重量)至約2% (重量:重量)的聚氧化乙烯’此 使得乾燥的試劑更具親水性也更結實。含括聚氧化乙烯, 此試劑更能忍受在試條組合時的機械打孔及使用試條時的 機械操作。此外,經乾燥的試劑包括約1 · 7 5 % (重量:重 量)至約17.5 % (重量:重量)的聚氧化乙烯,在含水試 樣加至試條區時,容易再度溶解或再度懸浮。 【實施方式】 本發明之生物感知器的較佳實施例之構件示於附圖1 200530582 (4) ' ' 、2、4和5。此生物感知器包括第一個絕緣底質1,其有 第一個表面22和第二個表面23。絕緣底質1可製自任何 可資利用的絕緣材料。基本上,塑膠(如:乙烯聚合物、 聚醯亞胺、聚酯和苯乙烯類提供所欲的電力和結構性質。 第一個絕緣底質1另包含凹痕2、缺口 3和輸出孔4。因 爲附圖1所示的生物感知器要以材料卷大量製造,所以必 須選擇柔軟度足以用於捲筒加工且韌度足以使最終生物感 > 知器具有用韌度的材料,特別佳的第一個絕緣底質1是7 密耳厚的 MELINEX3 29塑料,其是由ICI Films ( 34 1 1 Silverside Road,PO Box 1 5 3 9 1, W i 1 m i n g t ο η,D e 1 a w ar e 1 98 5 0 )提供的聚酯。 如附圖1所示者,導電軌5和6貼在第一個絕緣底質 1的第一個表面22上。軌5可以是工作電極,由導電材料 (如:鈀、鉑、金、碳和鈦)製成。軌6可以是平衡電極 ,由導電材料(如:鈀、鉑、金、銀、含銀合金、鎳一鉻 | 合金、碳、鈦和銅)製成。以貴金屬爲佳,因爲它們提供 更穩定的可再製電極表面。鈀因爲比貴金屬更不容易被氧 化且因其爲相當低廉的材料,所以是特別佳者。 較佳情況中,導電軌5和6附著在絕緣墊片(如:聚 醯亞胺或聚酯)上,以降低在拿取或製造試條期間內撕裂 電極材料的可能性。這樣的導電軌的例子是在UP ILEX聚 醯亞胺墊片上之表面電阻低於5歐姆/平方銷塗層(由 Courtalds-Andus Performance Films, Canoga Park,
California 提供)。 200530582 (5) ' 導電軌5和6代表生物感知試條的電極。這些電極的 距離必須足夠,使得發生於一個電極上的電化學情況不會 干擾到另一電極上的電化學情況。電極5和6之間的較佳 距離約1 . 2毫米。 附圖1所示的試條中,導電軌5是工作電極,導電軌 6是平衡電極或參考電極。軌6如果是由典型的參考電極 材料(如:銀/氯化銀)製得時,可以是參考電極。較佳 g 實施例中,軌5是鈀製的工作電極,軌6是亦製自鈀的平 衡電極且實質上與工作電極具相同尺寸。 也可以配備有三種電極,其中,試條包括額外的導電 軌位於導電軌6和輸出孔4之間。在三個電極排列時,導 電軌5是工作電極,軌6是平衡電極而介於導電軌6和輸 出孔4之間的第三個電極是參考電極。 覆於導電軌5和6上的是第二個絕緣底質7。第二個 絕緣底質7製自與第一個絕緣底質1類似或相同(以相同 | 爲佳)的材料。底質7有第一個表面8和第二個表面9。 第二個表面9以黏合劑(如··熱熔膠)附於底質1的表面 和導電軌5和6上。此膠的一個例子是DYNAPOLS-13 58 膠’侍自 Hills America, Inc·,220 Davidson Street,PO B〇X 682 l,Somerset,NJ 08 8 7 3。底質 7亦可包括第一個開 口 1 〇和第二個開口 n。第一個開口 1 〇使導電軌5和6外 露以與儀表(在試樣與試條的試劑混合之後,測定試樣的 一些電力性質)作電力連接。第二個開口 1 1使不同部分 的導電軌5和6外露以使試劑1 2施用在軌5和6的這些 -9- 200530582 (6) ., Ο 外露表面上。(附圖1中,導電軌5和6的整個寬度因開 口 1 1而外露。但是,也可以僅使作爲平衡電極或參考電 極之用的導電軌6的一部分寬度外露,只要至少約1 0 %的 寬度由開口 1 1外露即可。)此外,第二個絕緣底質7包 括凹痕1 9,其與附圖1所示的凹痕2相符。 試劑1 2是使試條進行測試的特定試劑。試劑1 2可施 用在由第二個開口 11定出範圍中之導電軌5和6的整個 | 外露表面上。也可以將試劑1 2施用於此區域中。例如, 若試條的此區域中的導電軌6具參考電極構造(如:銀/ 氯化銀),則試劑1 2僅須覆蓋此區域中的工作電極5外 露表面。此外,不須以試劑蓋住電極的整個外露表面,只 要電極的指定及可再製表面被試劑蓋住即可。 蓋住第一個表面8和第二個開口 1 1的一部分的是頂 部1 3。頂部1 3包括凹痕14和缺口 1 5。凹痕14和缺口 1 5 的形狀和位置使得它們直接覆於凹痕2和1 9及缺口 3上 | 。頂部1 3可製自塑膠材料(如:約2密耳至約6密耳厚 的透明或半透明聚酯膜)。頂部1 3有第一個表面1 6和第 二個表面1 7。頂部1 3的第二個表面1 7藉適當的黏合劑( 如:3Μ 945 8 丙烯物,得自 3Μ,Identification and Converter Systems Division,3 M Center,Building 220-7 W-03,St. Paul,MN 5 5 1 44 )附著於第二個絕緣底質7的第一 個表面8上。 較佳情況中,頂部1 3另包括透明或半透明視窗1 8。 視窗I 8的大小和位置使得頂部1 3附於第二個絕緣底質7 -10- 200530582 (7) ' / ,此視窗覆蓋導電軌5的整個寬度和導電軌6的至少約1 0 %寬度。 頂部1 3的第二個表面、開口 1 1的邊緣及絕緣底質1 的第一個表面22(及附於底質1的第一個表面22上的導 電軌5和6 )定義出毛細測試區。以開口 1 1的長度和寬度 定出此毛細區的長度和寬度,以第二個絕緣底質7的厚度 定出此區的高度。 _ 較佳的試條可以附圖3 a- 3 i所示的程序製造。絕緣底 材板21 ( MELINEX 2 3 9,7密耳厚,得自ICI )的一面以 熱熔黏合劑(DYNAPOL S- 1 3 5 8,得自Hiils )塗覆(附圖 3 a )。板2 1延線24切割,藉此形成有黏合劑覆於第一個 表面22上的第一個絕緣底質1及有黏合劑覆於第二個表 面9上的第二個絕緣底質7。(附圖3 b和3 c )以沖模打 孔機在底質7上形成第一個開口 10和第二個開口 11。( 附圖 3d)之後,在 Upilex墊片(得自 Ι AndusPerformance Films) 上之 鈀製的 導電軌 5 和 6 自捲 軸上先被切成約1.5毫米寬並覆於底質1的表面22上, 使得Upilex墊片與表面22相鄰。將底質7的表面9覆於 鄰近於底質1的表面22及鄰近於導電軌5和6處,藉此 形成附圖3 e所示的三明治結構。熱封此三明治結構。 之後,使試劑1 2分散於開口 1 1中並加以乾燥。(附 圖3 f)在試劑1 2乾燥之後’以沖模打孔孔機形成輸出孔 4。(附圖3 g )之後’包括親水塗層2 5和視窗1 8的頂部 1 3覆於開口】1 ’其覆蓋方式使得視窗1 8覆於導電軌5的 -11 - 200530582 (8) ' ^ 整個寬度及導電軌6的約一半寬度上。如附圖3 h所示者 由脫模襯墊脫下頂部1 3並黏合固定於表面8上。 最後,如附圖3 i所示者,以沖模打孔機在各個試條 上打孔。此沖模打孔機可以在有或無缺口 1 5的試條打孔 。若含括缺口 1 5,則頂點較佳角度是1 〇 5。。其他角度( 如約4 5 °至約1 0 5 ° )亦可用於缺口 1 5。此外,缺口 1 5 可以是單一缺口或多重缺口。 & 如前述者,試劑1 2分散於試條上之以開口 i 1定義出 的區域中。前述製法中,希望在施用試劑12之前,先使 用電暈處理開口 11。電暈處理用以提高表面22部分及因 開口 1 1而外露的導電軌5和6的表面能量,使得試劑1 2 均勻分佈及預先潔淨因開口 1 1而外露的導電軌5和6部 分。已經發現到預先潔淨導電軌5和6可大幅改善試條的 效能。電暈處理係於瓦特密度由約20至約90瓦特/公分 /秒、弧間隔約1密耳(0.040英吋)的條件下進行。 | 較佳方法中,此電暈處理以前述瓦特密度以全體形式 施用在附圖3 e所示的表面上。施用此處理之後的5分鐘 之內施用試劑1 2最爲有效,基本上是在4 5秒鐘之內施用 試劑1 2。 比較有利的狀況是:降低電暈處理於表面8上的作用 ’以確保試劑1 2完全留在開口 1 1中且與表面8的親和力 不會比與表面22部分及與因開口 1 1而外露的導電軌5和 6的親和力來得大。電暈消散程序(用以選擇性地降低全 面電暈處理程序的效果)用以降低在開口 1 1的網區(經 -12-
200530582 :, Ο) 加工的試條片)的處理效果。此電暈消散程序含 子水薄膜,使得水與表面8接觸,但不會與開口 接觸。水薄膜(以約1 · 5微米至約3.0微米厚(奢 水/平方米)爲佳)之施用可藉芯墊、橡皮版印月 常用的塗覆法來進行。之後,在施用試劑1 2之肓 強迫對流或紅外光線法,使水薄膜自表面乾燥。It 淨效果是:在施用試劑12之前,表面8的表面肯 地降低至低於6 2達因,且開口 1 1內區域表面維f 處理後的表面能量。 在較佳實施例中,試劑1 2經調配用以測定> 樣品中的葡萄糖。使用酵素醌蛋白質(含吡咯基 (PQQ))葡萄糖去氫酶和氧化還原介質氰化物· 較佳葡萄糖試劑的文獻如下:Quinoprotein dehydrogenase is Enzyme Commission No.1.1.99.17 步驟1 :製備NATROSOL的去離子水溶液。在 率不低於2 5 Orpm且攪拌時間不少於3 0分鐘的情況 0.45克NATROSOL-25 0M (微晶狀羥基乙基纖維素 Aqualon )加至414克去離子水中,可達到此目的 是使用三或四片渦輪型螺旋槳的頂部旋轉扇葉來達 的目的。螺旋槳尺寸和構造之選擇大部分以所用混 半徑爲基礎。所選用的螺旋槳基本上半徑大於混合 徑的7 5 %。 步驟2 :在混合速率不低於5 70rpm且攪拌時 於6 0分鐘的情況下,在得自步驟1的溶液中,逐 施用離 0和1 1 9.1克 或他種 ,使用 處理的 量有效 其電暈 體血液 喹咯啉 備一升 glucose 〇 攪拌速 下,將 ,得自 。最好 到混合 合容器 容器半 間不少 漸添加 -13-
