Polypeptide-based liquid-liquid phase separation (LLPS) has received considerable attention as it governs the formation of membraneless organelles in cells. However, detailed mechanistic understanding how one most prevalent cationic amino acids proteins, arginine, interacts with various biomolecules to induce and undergo morphogenesis remains be resolved. Herein, we report behavior transformation arginine-rich coacervates into vesicular structures upon introducing polyphosphates. Transformation vesicles was shown occur independent initial anionic counterparts driven by salt-bridge interactions between guanidinium groups arginine residues phosphates. We also investigate role intermolecular forces ionic effects on morphological further exploit their potential assembly artificial tissue-like constructs. Overall, our findings underpin a unifying principle for vesicle from potency reconstituting hierarchical biological microcompartments.

Abstract The ability to precisely control in vitro enzymatic reactions synthetic cells plays a crucial role the bottom‐up design of artificial cell models that can recapitulate key cellular features and functions such as metabolism. However, integration has been limited bulk or microfluidic emulsions without membrane, lacking more sophisticated higher‐order communities for reconstituting spatiotemporal biological information at multiple length scales. Herein, droplet microfluidics is utilized synthesize cell‐like polymersomes with distinct molecular permeability driven by external signals fuels. presence competing reverse reaction depletes active substrates shown enable demonstration fuel‐driven formation sub‐microcompartments within well realization out‐of‐equilibrium systems. In addition, different characteristics polymersome membranes are exploited successfully construct programmable network mimics communication heterogeneous community through selective transport.

Protocells offer a versatile material for dissecting cellular processes and developing simplified biomimetic systems by combining biological components with synthetic ones. However, gap exists between the integrity complex functionality of native organelles such as nuclei, bottom‐up strategies reducing functions within environment. Here, this is bridged incorporating nuclei into polymeric giant unilamellar vesicles (pGUVs) using double‐emulsion microfluidics. It shown that retain their morphology nuclear envelope integrity, facilitating import co‐encapsulated peptide‐based multicompartment micelles (MCMs) via localization signals (NLS). Importantly, it demonstrated machinery remains functional inside protocells, enriching GUV interior import‐promoting factors, delivery efficiency NLS‐MCMs significantly increases. The findings reveal nucleated protocells preserve function extended periods, providing new platform studying in simplified, yet biologically relevant, This approach opens avenues creating advanced biohybrid materials, offering opportunities to investigate organelle behavior interactions greater detail. establish foundation high‐throughput applications biology contribute valuable insights sustaining engineered systems.
