Cell membrane-derived nanomaterials for biomedical applications

Summary

This review examines how materials derived from cell membranes are being used to construct therapeutic and diagnostic nanotechnologies. Its central question is how nanoparticle systems can navigate complex biological environments more effectively by borrowing functions that cells already use for self-identification, signaling, compartmentalization, and interaction with surrounding tissues. The authors organize major approaches in which membrane material is directly incorporated into nanostructures, rather than reproducing each function with individually selected synthetic ligands. Across the reviewed examples, natural membrane interfaces are presented as a route to improve conventional nanomedicine and to enable applications that are difficult for unmodified particles. The principal conclusion is that biomimetic design represents an important shift from purely synthetic surface engineering toward functional biological materials. This is significant because the membrane can carry many coordinated components at once, potentially affecting circulation, targeting, immune interaction, detoxification, or sensing depending on its source. The abstract nevertheless provides a broad narrative overview, not a systematic comparison. It does not specify search methods, evidence quality, relative performance of membrane sources, or clinical outcomes, and it leaves unresolved questions about membrane purification, orientation, functional consistency, immunogenicity, pathogen transfer, storage, manufacturing scale, and regulation.
