Cover Story: Supported lipid bilayers (SLBs) are versatile models for studying cell membrane behavior using a variety of surface techniques. However, predominantly anionic SLBs on quartz crystals to represent the inner membrane of Gram-positive bacteria are currently not available. We report a robust method based on treating the quartz crystal with cationic aminopropyl trimethoxysilane. We found that anionic phosphatidylglycerol (PG) vesicles adsorbed and remained intact without creating a SLB, but mixed vesicles of PG with lysophosphatidylglycerol (LPG) led to stable SLBs. The dynamics of SLB formation showed that in contrast to zwitterionic lipids that display a two-step process of vesicle adsorption followed by their breakdown, the PG/LPG mixed vesicles ruptured instantaneously on contacting the quartz surface, resulting in a one-step SLB formation.
