    • Described herein is the synthesis of adhesive complex coacervates and their use thereof. The adhesive complex coacervates are produced by reacting (a) at least one poly anion comprising a plurality of activated ester groups, and (b) at least one polycation comprising a plurality of nucleophilic groups, wherein the nucleophilic groups react with the activated ester groups to produce a new oovalent bond between the polycation and the polyanion.The adhesive complex coacervates described herein have low interfacial tension with water and wettable substrates. When applied to a wet substrate they spread over the interface rather than beading up. The adhesive complex coacervates have numerous biological applications as bioadhesives and drug delivery devices. In particular, the adhesive complex coacervates described herein are particularly useful in wet or underwater applications and situations where water is present such as, for example, physiological conditions.
    • 本文描述了粘合剂复合凝聚层的合成及其用途。 通过使(a)至少一种包含多个活化酯基的多阴离子和(b)至少一个包含多个亲核基团的聚阳离子反应,生成粘合剂复合物凝聚层,其中亲核基团与活化的酯基团反应, 在聚阳离子和聚阴离子之间产生新的共价键。本文所述的粘合剂复合物凝聚层具有与水和可湿性底物的低界面张力。 当应用于湿底物时,它们分散在界面上而不是着色。 粘合剂复合物凝聚层具有许多生物应用作为生物粘合剂和药物递送装置。 特别地,本文所述的粘合剂复合物凝聚层在湿或水下应用和存在水的情况下特别有用,例如生理条件。
