Abstract Efficient cytosolic delivery of RNA molecules remains a formidable barrier for therapeutic strategies. Lipid nanoparticles (LNPs) serve as state-of-the-art carriers that can deliver intracellularly, exemplified by the recent implementation several vaccines against SARS-CoV-2. Using bottom-up rational design approach, we assemble LNPs contain programmable lipid phases encapsulating small interfering (siRNA). A combination cryogenic transmission electron microscopy, tomography and small-angle X-ray scattering reveals form inverse hexagonal structures, which are present in liquid crystalline nature within LNP core. Comparison with lamellar presence enhances intracellular silencing efficiency over structures. We then demonstrate exhibit an situ transition from to phase upon interaction anionic membranes, whereas containing pre-programmed bypass this more efficient one-step mechanism, explaining increased effect. This defined structures aids understanding nano-bio interface adds substantial value design, optimization use.
