TEM images of NPs/complexes. Blank CS NPs (0.3% w/v CS) (a), DsiRNA-CS NPs ((b), (d), (f), and (h)), and DsiRNA-CS complexes ((c), (e), (g), and (i)) of 0.1%, 0.2%, 0.3%, and 0.4% w/v of CS, respectively. The magnification of the images were 43 kx ((a), (c), (d), and (f)), 60 kx ((e) and (g)), 20500x (b), 165 kx (h), and 135 kx (i).
