Abstract
【解決手段】実験用消耗品を式(I)
[式中R1、R2及びR3は独立に水素、アルキル、ハロアルキル又は場合によりハロ置換されたアリールより選択され、また、R4はX-R5基であり、式中R5はアルキル又はハロアルキル基であり、また、Xは結合、式-C(O)O(CH2)nY-で示される基(式中nは1ないし10の整数であり、Yは結合又はスルホンアミド基である)、又は-(O)pR6(O)q(CH2)t-基(式中R6は場合によりハロ置換されたアリールであり、pは0又は1、qは0又は1であり、また、tは0ないし10の整数であり、ただしqが1ならばtは0以外である)である。]で示される化合物を含んでなるパルスプラズマに、該消耗品の表面を暴露することによって形成される高分子被膜を有する実験用消耗品。
【選択図】なし
Description
で示される化合物を含んでなるパルスプラズマに、該消耗品の表面上に高分子層を堆積させるに足る時間にわたり、暴露することによって形成される高分子被膜を有する実験用消耗品が提供される。
本発明の表面改質が大いにプラスとなる別種の実験用消耗品は膜である。これにはろ過膜として使用されるものやイムノアッセイ装置に使用されるものなどがある。これらの膜は多孔質材料を素材とする。素材の細孔は液体を通過させる必要がある。ろ過膜の場合、特定の粒径を超える粒子は膜表面上に保持される。イムノアッセイに使用される膜の場合、膜の細孔は液体と金又はラテックス粒子などのような小粒子を通過させる必要がある。これらの膜はこうした機能を果たしうるものの、一般に、液体吸収性の材料たとえばセルロースを素材とする。これは、使用中に飽和状態になるため、相当量の液体が膜内に残留することを意味し、ごく少量の液体が使用される場合には問題となる。
R5のアルキル鎖は好適には炭素原子を2個以上、好適には2〜20個、好ましくは6〜12個含む。
R1、R2及びR3のアルキル鎖は一般に炭素原子数1〜6であるのが好ましい。
好ましくは、R5はハロアルキル基であり、なお好ましくはペルハロアルキル基、特に式CmF2m+1(式中mは1以上、好適には4ないし12の整数、たとえば4、6又は8である)で示されるペルフルオロアルキル基である。
R1、R2及びR3のアルキル基は好適には炭素原子数が1ないし6である。
一実施形態では、R1、R2及びR3のうち少なくとも1つは水素である。特定の実施形態ではR1、R2及びR3はすべて水素である。ただし、さらなる実施形態ではR3はメチル又はプロピルなどのアルキル基である。
Yの好適なスルホンアミド基は式N(R7)SO2-で示される基を含む(式中R7は水素又はアルキル、たとえばC1-4アルキル、特にエチル又はメチルである)。
CH2=CH-R5 (II)
(式中R5は式(I)との関連で定義したとおりである。)
で示される化合物である。
ただし、好ましい実施形態では式(II)で示される化合物は式(III )
CH2=CR7C(O)O(CH2)nR5 (III )
(式中nとR5は式(I)との関連で定義したとおりであり、R7は水素、C1-10アルキル又はC1-10ハロアルキルである。)
で示されるアクリレートである。特にR7は水素又はC1-6アルキル、たとえばメチルである。式(III )で示される化合物の具体例は式(IV)
で示される化合物である。
で示される化合物を気相状態で含んでなるパルスプラズマに、該消耗品の表面に高分子層を堆積させるに足る時間にわたり、暴露する工程を含む方法を提供する。
以下、実施例をもって本発明を詳しく説明する。
ピペットチップ
一組のポリプロピレン製ピペットチップを処理容量約300リットルのプラズマ室内に置いた。プラズマ室を必要な気体又は蒸気の供給管に、質量流量制御器及び/または質量流量計並びに混合噴射装置を適宜介して、接続した。
プラズマ室を基準圧の3〜10mtorrまで排気し、次いで80mtorrに達するまでヘリウムを20sccmで導入した。次に300W、13.56MHzの高周波を使用して連続プラズマを4分間発生させた。
その後、式
このピペットチップは液体の残留がほぼ解消され、最大限のサンプル回収を可能にするなど、性能が著しく向上していた。
ろ紙
実施例1と同じ方法を用いて、セルロースろ紙(Whatman No.1)をプラズマ室内に置き、同じ条件下で処理した。プラズマ改質処理したろ紙は外観が変わらず、風合いも同じなので、見ても触れても区別がつかないと判明した。撥水性も表面に水玉が形成され、それが楽に転げまわるほどである。だが、本発明の方法は細孔を塞ぐものではないので、そうした水滴も十分な圧力が加わればこの細孔性ろ紙を透過させられた。処理したろ紙は濡れないままで、ろ過機能を果たすことができる。
