'Marker-of-self' functionalization of nanoscale particles through a top-down cellular membrane coating approach

Nanoscale. 2013 Apr 7;5(7):2664-8. doi: 10.1039/c3nr00015j.

Abstract

We investigate the 'marker-of-self' functionalization of nanoparticles through coating of natural RBC membranes. The membrane translocation approach is shown to be highly efficient and bestows nanoparticles with correctly oriented and functional immunomodulatory proteins such as CD47 at equivalent density to natural RBCs.
