Figure 4.
SEM images of different organic NFs after air-drying at 36 °C (a–f) and 65 °C (g–i). Protein guests: (a) f-SHS@Cyt; (b) f-SHS@mCh; (c) f-SHS@Ova; (d) f-SHS@DsR. pDNA guests: (e) f-SHS@pCri, (f) f-SHS@pGFP; (g) f-SHS alone. Protein guest: (h) f-SHS@Ova; small molecule guest: (i) f-SHS@RhB. The NFs from f-SHS@Ova (c) were observed primarily on the carbon section of the SEM grid, in contrast to the rest of NFs studied, which formed on the copper section of the grid.
