Self-assembled intertwining DNA-RNA nanocapsules (iDR-NCs) represent a general technology to construct hybrid DNA-RNA nanostructures that can be further loaded with hydrophobic peptide therapeutics. The iDR-NCs developed in this work served as potent synergistic nanovaccines for personalized combination cancer immunotherapy. The TESCAN GAIA3 Ga Focused Ion Beam Scanning Electron Microscope was used to prepare and image cross-sections of iDR-NCs which allowed studying their internal structure.
