Electron microscopy analysis of AuNP-loaded Enc(neg) and empty Ftn(pos) crystals. (A) Heterobinary crystals based on AuEnc(neg)/eFtn(pos) were transferred on Si-wafer and investigated via scanning electron microscopy. Scale bar: 15 μm. (B) Further zoom on the crystal surface reveals a cubic arrangement of spheres (see the inset). Scale bars: 500 nm and 100 nm (inset). (C) Transmission electron microscopy enabled the visualization of a well-ordered nanoparticle lattice. Measured distances fit to the (101) plane of a cubic crystal system (see the inset). Scale bar: 10 nm.
