溶液調製
第一反応性前駆体:リン酸バッファーpH4.04中PEG−ジアクリレートの80%溶液を調製した。この溶液にPEG−NHSを、0.13g/mlの濃度で加えた(3mlのリン酸バッファー中80%ジアクリレート中0.39グラムのPEG−NHS)。
等しい体積の第一および第二反応性前駆体を、別々のシリンジにロードした。シリンジを接続し、溶液を15秒間混合した。次に、ヒドロゲルの完全な架橋を確保するために、溶液を15分間おいた。
それから各架橋ヒドロゲルを、それぞれのシリンジから除去し、いくつかのシリンダに切った。それから、架橋ヒドロゲルを様々な量のUV光(表2参照)に曝露して開始性前駆体の架橋を開始させ、開始性ヒドロゲルを形成した。ゲルのシリンダに長い針を貫通させ、UV源の下に配置し、回転させて均一に硬化させた。
シリンダが硬化したら、各々を12mmのフラットプローブの下に配置し、最初の高さの最大80%まで、または壊れるまで、0.08mm/秒の速度で20グラムのトリガー力および5グラムの破壊感度で圧縮した。各硬化ヒドロゲルについての結果が、表2に記録されている。図8は、表2のデータを示す棒グラフである(サンプルと100マイクロリットルの光開始剤)。図9は、開始性ヒドロゲル(上の線)と非開始性ヒドロゲル(下の線)の比較である。
第二ヒドロゲル前駆体中のリジンの代わりにトリリジンを使用して、実施例1の調製を繰り返した。試験の結果が、下表3に提供される。
本開示は、ヒドロゲル組成物およびそれを使用する方法に関する。ヒドロゲル組成物は、接触時に互いに反応する前駆体ならびに開始剤との接触時に反応する前駆体を含みうる。ある実施形態では、もたらされるヒドロゲルは、様々なレベルの架橋と、より高密度の領域およびより低密度の領域を有しうる。
