Engineering biological interactions on the nanoscale

Summary

This review discusses biomimetic engineering as a means of controlling how nanoparticles interact with biological systems. Conventional nanoscale platforms already support drug delivery, detoxification, and vaccination, but their performance depends on avoiding unwanted adsorption or clearance while engaging the intended cells, matrix, or molecules. The article centers on cell-membrane-coated nanoparticles, which transfer a natural cellular surface onto a synthetic core. Because cells have evolved specific interactions with other cells, extracellular matrix, and soluble biomolecules, the coating can reduce undesirable nonspecific contact and strengthen target-relevant binding without reconstructing every ligand individually. The review surveys the state of this platform and its use across multiple biomedical applications rather than presenting a new dataset. Its principal synthesis is that membrane coating provides a top-down method for programming biological identity at the nanoscale: the source cell supplies a coordinated set of interaction features, while the core supplies engineered cargo or material function. The significance is a general interface strategy that may make nanoparticles more selective and biologically compatible. The abstract does not compare membrane sources or applications quantitatively, describe review methods, or assess manufacturing consistency, immune risk, and clinical evidence.
