摘要

杯形是细胞和细胞器的动态形态。为了阐明生物杯状形态的形成,本研究从合成高分子化学的角度对两亲二嵌段共聚物组成的杯状囊泡进行了研究。采用光氮基介导的可控/活性自由基聚合技术,将聚(甲基丙烯酸)-嵌段聚(甲基丙烯酸正丁基-随机-甲基丙烯酸)PMAA-b-P(BMA-r-MAA)在甲醇水溶液中聚合诱导自组装得到杯状小泡。场发射扫描电镜观察表明,由于疏水P(BMA-r-MAA)块链的延伸,在聚合后期突然形成杯状囊泡。在早期阶段,聚合产生球形囊泡而不是杯状。随着聚合过程中疏水区块链的延伸,球形囊泡的尺寸减小,并伴随着附着在囊泡上的小颗粒的产生。由于疏水链的进一步延伸,囊泡的大小继续减小;然而,它们突然长成了杯状的小泡。这种增长是由于疏水链的延伸导致共聚物临界堆积形状的变化。这些发现有助于更好地了解生物杯状囊泡

Mechanisms of Cup-Shaped Vesicle Formation Using Amphiphilic Diblock Copolymer
A cup shape is a dynamic morphology of cells and organelles. With the aim of elucidating the formation of the biotic cup-shaped morphology, this study investigated cup-shaped vesicles consisting of an amphiphilic diblock copolymer from the aspect of synthetic polymer chemistry. Cup-shaped vesicles were obtained by the polymerization-induced self-assembly of poly(methacrylic acid)-block-poly(n-butyl methacrylate-random-methacrylic acid), PMAA-b-P(BMA-r-MAA), in an aqueous methanol solution using the photo nitrox-ide-mediated controlled/living radical polymerization technique. Field emission scanning electron microscopic observations demonstrated that the cup-shaped vesicles were suddenly formed during the late stage of the polymerization due to the extension of the hydrophobic P(BMA-r-MAA) block chain. During the early stage, the polymerization produced spherical vesicles rather than a cup shape. As the hydrophobic block chain was extended by the polymerization progress, the spherical vesicles reduced the size and were accompanied by the generation of small particles that were attached to the vesicles. The vesicles continued to reduce the size due to further extension of the hydrophobic chain; however, they suddenly grew into cup-shaped vesicles. This growth was accounted for by a change in the critical packing shape of the copolymer due to the hydrophobic chain extension. These findings are helpful for a better understanding of the biotic cup-shaped vesicle
