一般說明
聚乙烯亚胺是一种亲水性聚合物，作为一种非病毒合成载体，广泛用于体内递送治疗性核酸。由于其优异的理化性质，它被应用于蛋白质的分离和纯化、二氧化碳吸收、药物载体、废水处理、生物标记等多个领域。
應用
支链型PEI可作为前体合成共轭多聚体，用于高效基因转染。PEI与Jeffamine聚醚的共轭化和PEI氨基的胍化可降低多聚体的细胞毒性，并保护其在血清蛋白存在下不会发生聚焦。
PEI 浸渍竹炭可用作CO2吸附剂。PEI中存在大量的氨基基团，可在酸碱作用下与CO2发生反应，增强竹炭的吸附能力。
它还可用于制备对有机药物分子具有高配位能力的交联水溶性聚合物。

Insurmountable detection challenges will impede the development of many of the next-generation of lab-on-a-chip devices (e.g., point-of-care and real-time health monitors). Here we present the first membrane-based, microfluidic sample preconcentration method that is continuous, quantifiable, simple, and capable of working
