我们报告了巨型单层囊泡(GUV)的光脂掺杂,该囊泡融合与小的单层光脂囊泡(PSUVS),从而实现了膜特性的追溯光学控制。我们观察到,如果磷脂是中性的,则囊泡融合是光依赖性的。电荷介导的融合涉及阴离子和阳离子脂质分子,即使在没有光线暴露的情况下,也可以增强整体融合性能和掺杂效率。使用磷脂酰胆碱类似物与一个或两个偶氮苯照片开关(Azo-PC和Dazo-PC)会影响域的形成,弯曲刚度以及所得囊泡的形状,以响应辐照。此外,我们表明,使用红色吸收的光脂(Red-Azo-PC)可以将光膜控制扩展到长波长。结合在一起,我们的发现提出了一种具有吸引力且实用的方法,用于精确递送光脂质,为膜功能的光学控制提供了新的前景。
We report on photolipid doping of giant unilamellar vesicles (GUVs) via vesicle fusion with small unilamellar photolipid vesicles (pSUVs), which enables retroactive optical control of the membrane properties. We observe that vesicle fusion is light-dependent, if the phospholipids are neutral. Charge-mediated fusion involving anionic and cationic lipid molecules augments the overall fusion performance and doping efficiency, even in the absence of light exposure. Using phosphatidylcholine analogs with one or two azobenzene photoswitches (azo-PC and dazo-PC) affects domain formation, bending stiffness, and shape of the resulting vesicles in response to irradiation. Moreover, we show that optical membrane control can be extended to long wavelengths using red-absorbing photolipids (red-azo-PC). Combined, our findings present an attractive and practical method for the precise delivery of photolipids, which offers new prospects for the optical control of membrane function.
