  摘要：

  由能够与亲水性和疏水性有效载荷同时加载的两亲性聚合物自组装的超分子囊泡，也被称为聚合物囊泡，在药物递送应用中显示出有希望的潜力。在这里，我们报告通过两亲性二嵌段共聚物，聚（环氧乙烷）-b-聚（2-（（（（（5-甲基-2-（2,4,6-三甲氧基苯基）-1,3-二恶烷-5-基）甲氧基）羰基）氨基）甲基丙烯酸乙酯）（PEO- b-PTTAMA），是使用基于PEO的macroRAFT试剂通过pH响应单体（即TTAMA）的可逆加成-断裂链转移（RAFT）聚合合成的。然后，通过TEM和DLS测量证实，所得的两亲性二嵌段共聚物会自组装成由亲水性PEO电晕和pH响应性疏水性双层组成的囊泡。疏水性双层中含有环状亚苄基乙缩醛的聚合物囊泡在中性pH值下相对稳定，而在暴露于酸性pH值条件下，它们水解后会释放出疏水性2,4,6-三甲氧基苯甲醛并同时生成亲水性二醇部分，这可能通过紫外/可见光谱，SEM和TEM观察进行

• Stimuli-Responsive Supramolecular Assemblies of Linear-Dendritic Copolymers

  With the goal of developing a pH-responsive micelle system, linear-dendritic block copolymers comprising poly(ethylene oxide) and either a polylysine or polyester dendron were prepared and hydrophobic groups were attached to the dendrimer periphery by highly acid-sensitive cyclic acetals. These copolymers were designed to form stable micelles in aqueous solution at neutral pH but to disintegrate into unimers at mildly acidic pH following loss of the hydrophobic groups upon acetal hydrolysis. Micelle formation was demonstrated by encapsulation of the fluorescent probe Nile Red, and the micelle sizes were determined by dynamic light scattering. The structure of the dendrimer block, its generation, and the synthetic method for linking the acetal groups to its periphery all had an influence on the critical micelle concentration and the micelle size. The rate of hydrolysis of the acetals at the micelle core was measured for each system at pH 7.4 and pH 5, and it was found that all systems were stable at neutral pH but underwent significant hydrolysis at pH 5 over several hours. The rate of hydrolysis at pH 5 was dependent on the structure of the copolymer, most notably the hydrophobicity of the core-forming block. To demonstrate the potential of these systems for controlled release, the release of Nile Red as a "model payload" was examined. At pH 7.4, the fluorescence of micelle-encapsulated Nile Red was relatively constant, indicating it was retained in the micelle, while at pH 5, the fluorescence decreased, consistent with its release into the aqueous environment. The rate of release was strongly correlated with the rate of acetal hydrolysis and was therefore controlled by the chemical structure of the copolymer. The mechanism of Nile Red release was investigated by monitoring the change in size of the micelles over time at acidic pH. Dynamic light scattering measurement showed a size decrease over time, eventually reaching the size of a unimer, thus providing evidence for the proposed micelle disintegration.
