Acute lung injury (ALI) remains a critical clinical challenge characterized by uncontrolled inflammation, oxidative stress, and immune dysregulation, with limited therapeutic options and high mortality. In recent years, biomimetic nanoplatforms-including those derived from cell membranes, extracellular vesicles (EVs), and hybrid biological interfaces-have emerged as transformative tools for ALI management. Unlike conventional nanocarriers, these systems reproduce natural intercellular communication and immune evasion mechanisms, thereby achieving precise lung targeting, sustained therapeutic delivery, and coordinated regulation of inflammation and tissue repair.This review provides a comprehensive and mechanistic overview of biomimetic nanoplatforms in ALI therapy, with an emphasis on membrane-derived, EV-based, and hybrid nanosystems. We further introduce less-explored biomimetic strategies, including protein-, bacterial-, and virus-inspired nanoparticles, to expand the conceptual framework of biological mimicry in pulmonary nanomedicine. Beyond summarizing progress, we critically discuss key translational barriers-immunogenicity, model fidelity, and large-scale manufacturing-and propose integrative solutions leveraging artificial intelligence, organ-on-chip technologies, and precision medicine approaches.By offering a unified perspective on the design, function, and translational roadmap of biomimetic nanotherapeutics, this review highlights how the integration of biology-inspired engineering and pulmonary pathophysiology could pave the way toward personalized and clinically viable nanomedicine for ALI.
