Plasma Gelation as an Overlooked Determinant of Transfection Efficiency in Protein Corona‐Coated Lipid Nanoparticles: Implications for In Vitro–In Vivo Translation

Advanced Healthcare Materials, EarlyView.
Upon contact with plasma, lipid nanoparticles (LNPs) rapidly acquire a protein corona (PC) that redefines their biological identity. In calcium‐containing environments, these coronated particles trigger the formation of a gel‐like plasma network, profoundly altering their transport properties and reducing their effective availability.
