Description
Tg1s、Tg2s>Tg1f、Tg2f ・・・(1)
(マイクロ流路チップの構成)
図1および図2は、本発明の実施の形態1に係るマイクロ流路チップ100の構成を示す図である。図1は、マイクロ流路チップ100の平面図である。図2Aは、図1に示されるA−A線の断面図であり、図2Bは、図1に示されるB−B線の断面図であり、図2Cは、図1に示されるC−C線の断面図である。
Tg1s、Tg2s>Tg1f、Tg2f ・・・(1)
このように、式(1)を満たすことができれば、第1基板120、第1フィルム140、第2フィルム160および第2基板180を構成する樹脂は、前述した樹脂から任意に選択することができる。前述の式(1)を満たす市販品の組み合わせとして、例えば以下の組み合わせがある。第1基板120および第2基板180を構成する市販の樹脂としては、例えばゼオネックスF52R(Tg1s156℃;日本ゼオン株式会社)を使用できる。また、第1フィルム140を構成する市販の樹脂としては、例えばゼオノアフィルムZF14(Tg1f136℃;日本ゼオン株式会社)を使用できる。また、第2フィルム160を構成する市販の樹脂としては、例えばゼオノア1060R(Tg2f100℃;日本ゼオン株式会社)を使用できる。なお、第2フィルム160を第2基板180に接合するための温度が第1フィルム140に伝わったとしても、流路220の変形を抑えられるように、Tg1f≧Tg2f−5(℃)であることが好ましく、Tg1f≧Tg2fであることがより好ましい。
本実施の形態に係るマイクロ流路チップ100の製造方法は、特に限定されない。たとえば、第1基板120および第1フィルム140を第1接合温度T1で接合した後に、第2フィルム160および第2基板180を第2接合温度T2でさらに接合してもよい(製造方法1)。また、第1基板120、第2フィルム160および第2基板180を第2接合温度T2で接合した後に、第1フィルム140を第1接合温度T1でさらに接合してもよい(製造方法2)。流路の形状が変形しないように第1接合温度T1を設定することが必要である。
図8は、製造方法1の各工程を示す図である。図8Aは、製造方法1の第1工程を示す図であり、図8Bは、製造方法1の第2工程を示す図である。たとえば、第1基板120および第2基板180は、前述した樹脂を用いた射出成形法により作製されうる。
図9は、製造方法2の各工程を示す図である。図9Aは、製造方法2の第1工程を示す図であり、図9Bは、製造方法2の第2工程を示す図である。製造方法2における第1基板120および第2基板180は、製造方法1と同じように射出成形により作製されうる。
次に、マイクロ流路チップ100の取扱方法(使用方法)について説明する。まず、第1液体導入部231および第2液体導入部232が上に向かってに開口するように配置する。このとき、液溜部240は、流路220より上側に位置するように配置される。まず、液体が充填されたマイクロピペットのマイクロチップを第1液体導入部231に圧入する。このとき、マイクロチップの外周面と第1液体導入部231の開口部とが密着して、マイクロチップが第1液体導入部231に固定される。
以上のように、本実施の形態1に係るマイクロ流路チップ100は、第1分岐溝121が形成されていない第1基板120の第2面に対向して第2フィルム140および第2基板180が配置されており、かつ第1基板のガラス転移温度をTg1s、第1フィルムのガラス転移温度をTg1f、第2基板のガラス転移温度をTg2s、第2フィルムのガラス転移温度をTg2fとしたとき、Tg1s、Tg2s>Tg1f、Tg2fを満たすため、第1基板120および第2基板180を適切に接合することができる。
実施の形態2に係るマイクロ流路チップ300は、第1基板320の第2面(裏面)と、第2基板380の第1面(表面)との形状が実施の形態1に係るマイクロ流路チップ100と異なる。そこで、実施の形態1に係るマイクロ流路チップ100と同じ構成は、同一の符号を付してその説明を省略する。
以上のように、実施の形態2に係るマイクロ流路チップ300は、実施の形態1に係るマイクロ流路チップ100と同様の効果を有する。さらに、実施の形態2に係るマイクロ流路チップ300では、第1基板320の第2面と、第2基板380の第1面とが相補的に形成されているため、第1基板320と第2基板380とが接する表面積が大きくなり、さらに第1基板320および第2基板380を適切に接合することができる。
