Fabrication and size distribution of MPs with a macropore. (a) SEM and (b) TEM micrographs of the fabricated MPs (i: low mag. and ii: high mag.) Pored MPs were successfully fabricated using pH sensitive polymer, Eudragit S100 by a newly developed method. (c) MP size distribution (i) and pore to MP size ratio (radius of pore (Rpore)/radius of MP (RMP)) distribution (ii) obtained from SEM images of pored MPs (n = 210).
