Characterization of PHMs and M-PHMs and their ability to complex miR-124. (A) The morphology of MTX, MTX-PEI-LA, PHMs, M-PHMs was obtained by field emission scanning electron microscopy (FESEM). The critical micelle concentration (CMC) of PHMs (B) and M-PHMs (C) was then obtained by measuring conductivity. The ability of PHMs (D), M-PHMs (E) to complex miR-124 was investigated by agarose gel electrophoresis. Nitrogen to phosphate ratios (N/P) of PHMs or M-PHMs to miR-124 varied from 0/1 to 20/1. N/P of 0/1 referred to the unencapsulated free miR-124. N/P of 1/0 referred to the vectors without miR-124.
