我们研究了通过在硅衬底上覆盖一层脂质双层来将荧光探针限制在微孔中的最佳结构。我们修改了井的结构,以防止脂膜落入其中,并且孔口处的突出形状提高了限制的可能性。限制在井中的钙黄绿素的荧光强度在一小时或更长时间内保持不变,表明探针在井中保持稳定,没有流出。用悬浮膜封闭的人工细胞是膜蛋白功能分析的一种很有前途的工具。
We investigated the optimum architecture for confining fluorescent probes in microwells on a Si substrate by covering it with a lipid bilayer. We modified the structure of the wells to prevent the lipid membrane from falling into them, and the overhang shape at the aperture improved the probability of confinement. The fluorescence intensity from the calcein confined in the wells remained unchanged for one hour or more, indicating that the probes remain stably in the wells without flowing out. An artificial cell sealed with the suspended membrane is a promising tool for the functional analysis of membrane proteins.
