surpasses that of commercial transfection agents, lipofectamine 2000 (Lipo) and polyethylenimine (PEI). CCP is also highly fluorescent, with 43% quantum yield in water, and exhibits excellent photostability, which allows for real‐time tracking the location of gene delivery and transfection. These features and capabilities represent a major step toward designing and applying conjugated polymers that function
固有荧光阳离子聚芴(CCP)被设计,合成,其特征在于,并检验作为质粒DNA(pDNA的)递送载体。这种材料有利于核酸结合,封装和高效的细胞摄取。CCP能有效保护质粒DNA抗核酸酶降解,这是必要的基因携带者。绿色荧光蛋白(GFP)表达实验表明,CCP可以实现的pDNA的有效递送和转染编码GFP基因与92%的效率,这超过,商业转染剂的,脂质体2000(脂微球)和聚乙烯亚胺(PEI)。CCP也是高度荧光的,在水中的43%的量子产率,并表现出优良的光稳定性,这允许实时跟踪基因递送和转染的位置。这些特性和功能代表朝向成像和治疗应用设计和应用的共轭聚合物该功能的重要步骤。
