This paper reports a non-phase separation method to prepare a novel type of Janus vesicle, which contains different quantum dots (QDs) in its two hemispheres. The Janus vesicles were generated through the fusion of cyclodextrin or adamantane-functionalized hyperbranched polymer vesicles incorporated with QDs, driven by the intervesicular host–guest molecular recognition. Both the vesicle structure and the real-time membrane fusion process were revealed under fluorescence microscopy, by taking advantage of the giant size, great stability, and controllable surface functionality of the hyperbranched polymer vesicles (BPs). More interestingly, a potential magnetically controlled printing application of the Janus vesicles with Fe₃O₄-containing hemispheres by their monolayer patterning in water was demonstrated, which realized the first “printing” of ordered vesicles.

通过膜融合产生的Janus量子点囊泡†

本文报道了一种无相分离方法，用于制备新型Janus囊泡，该囊泡在其两个半球中包含不同的量子点（QD）。Janus囊泡是通过将环糊精或金刚烷官能化的超支化聚合物囊泡与QDs融合而产生的，该囊泡是通过囊间主客体分子识别而驱动的。利用超支化聚合物囊泡（BPs）的巨大尺寸，出色的稳定性和可控制的表面功能，在荧光显微镜下揭示了囊泡的结构和实时膜融合过程。更有趣的是，具有Fe ₃ O ₄的Janus囊泡的潜在磁控印刷应用通过在水中的单层构图证明了含有半球的半球，这实现了有序囊泡的首次“印刷”。
