Abstract Designing well‐ordered, multifunctional layered membranes with high selectivity and long‐term stability remains a significant challenge. Here, simple strategy is introduced that utilizes charge repulsion between graphene oxide (GO) engineered bacteria to induce liquid crystal formation, enabling their layer‐by‐layer self‐assembly on polyethersulfone membrane. The interlayer pressure flattens the bacteria, removing water forming densely packed structure. This compression decreases spacing functional groups, leading robust hydrogen bonding network enhancement in mechanical properties (12.42 times tensile strength increase). Notably, preserves activity of super uranyl‐binding protein which selectively coordinates uranyl (UO 2 2+ ) through high‐affinity coordination bonds, recognition sieving target ions. membrane demonstrates near 100% rejection UO , K/U, V/U ≈140 ≈40, respectively, while maintaining stability. provides versatile platform for precise design high‐performance membranes, advancing field molecular transport energy environmental applications.
