Cell membrane coating nanotechnology

Summary

This review evaluates cell-membrane coating as a general method for improving how therapeutic, preventive, and diagnostic nanoparticles interact with living systems. Rather than rebuilding complex cellular functions one ligand at a time, the platform transfers naturally derived membranes onto synthetic nanoparticle cores. The retained membrane interface can provide multiple biological recognition and communication features at once, while the core supplies application-specific physical properties or cargo capacity. The authors organize and assess the rapidly growing literature on this top-down strategy, including uses that extend beyond conventional drug delivery. Their principal conclusion is that membrane coating is comparatively straightforward, adaptable across nanomaterials, and capable of augmenting established carriers with sophisticated biointerfacing functions that are difficult to reproduce synthetically. The significance lies in treating a cell surface as an integrated functional material, potentially enabling more biologically compatible and targeted nanomedicines without redesigning every membrane component. At the same time, the review characterizes the field as young and still under development. The abstract provides no systematic comparison of membrane sources or fabrication methods, no quantitative clinical evidence, and no resolution of manufacturing consistency, membrane integrity, storage, immunological risk, or regulatory scalability.
