Abstract
Biomimetic cell membrane-coated nanoparticles (BMCNPs) are an attractive drug delivery platform that combines the advantages of an inorganic core with the biological functionality of a natural cell membrane. This hybrid design merges the versatility of engineered nanomaterials with the complexity and specificity of biological systems, enabling prolonged circulation, immune evasion, enhanced tissue targeting, and improved therapeutic efficacy. In this review, we explore the in vivo behavior of BMCNPs, focusing on their interactions with biological barriers, including evasion of mononuclear phagocyte system clearance, biodistribution patterns, and circulation kinetics. We also examine how membrane source and surface properties influence targeting efficiency and delivery outcomes, while highlighting key considerations and emerging strategies to optimize therapeutic performance and translational potential.
