Abstract

The continued evolution of biomedical nanotechnology has enabled clinicians to better detect, prevent, manage, and treat human disease. In order to further push the limits of nanoparticle performance and functionality, there has recently been a paradigm shift towards biomimetic design strategies. By taking inspiration from nature, the goal is to create next-generation nanoparticle platforms that can more effectively navigate and interact with the incredibly complex biological systems that exist within the body. Of great interest are cellular membranes, which play essential roles in biointerfacing, self-identification, signal transduction, and compartmentalization. In this review, we explore the major ways in which researchers have directly leveraged cell membrane-derived biomaterials for the fabrication of novel nanotherapeutics and nanodiagnostics. Such emerging technologies have the potential to significantly advance the field of nanomedicine, helping to improve upon traditional modalities while also enabling novel applications.

Keywords: Biomimetic nanoparticle; Cell membrane; Detoxification; Drug delivery; Imaging; Immunotherapy.

Fig. 1. Cell membrane-based strategies for nanoparticle functionalization
A) Many cellular properties are determined by membrane composition, including the different proteins and glycan structures that are present. B) Examples of different cell membrane-based design strategies for fabricating biomimetic nanoparticles. Single molecule or subunit derivatives of cell membrane glycans and proteins can be used as functional ligands. Biomacromolecule components of the cell membrane, such as proteins and glycans, can be used to add specific functionalities. Further, entire cell membranes can be leveraged either directly as vesicular structures or as the coating material for a nanoparticulate core.
