一般描述

聚乙二醇(PEG)是一种合成亲水性生物相容聚合物,在生物医学和其他应用中广泛使用。PEG无毒、经FDA批准、通常无免疫原性,常用于许多生物医学应用,包括生物结合、药物递送、表面官能化和组织工程设计。在药物递送应用中,PEG可用作抗体-药物偶联物(ADC)的接头或用作纳米粒子的表面包膜,以改善全身性药物递送。

应用

可与炭黑结合使用形成导电复合材料。 可利用聚(乙二醇)的聚合物纳米球进行药物递送。
聚乙二醇(PEG)已被用作对猪主动脉平滑肌细胞(PAOSMC)上的磁性细菌纤维素(MBC)防护膜进行合成和体外安全性评估的包膜剂。PEG为细胞培养提供了相容的表面,因为未包膜的氧化铁NP公认具有细胞毒性。在研究聚乙烯吡咯烷酮微针使用猪皮、成年人类皮肤类似物和人类包皮等经皮递送功能性胶原的有效性时,它还被用作增塑剂。据报道,此类微针通过各种分析和生物分析技术进行了鉴定。
