Scanning Electron Microscopic characterization of CNPs decorated with HA2 and M2e recombinant proteins and mRNA. A Field Emission Scanning Electron Microscope (FESEM) analysis of empty CNPs, RNA-CNPs, protein-CNPs, and RNA–protein CNPs. Each specimen was observed at 100 K magnification. B Particle size distribution was determined from randomly selected 100 particles on each image. Particle size was measured in “nm”.
