Morphological and physical characteristics of the microcrystals-loaded MSs. Representative micrograph of (A) intact and (B) cross-sectioned microcrystals-loaded MS (F4), (C) hyperspectral image of microcrystals-loaded MSs, and (D) XRD patterns of (a) TA microcrystals, (b) blank MS, (c) F4 MS (drug:polymer = 1:5), and (d) F8 MS (1:10); Notes: Inset in (B) is ×5000 magnified images and the arrow points to the TA crystal surrounded by the polymeric matrices. In the hyperspectral image (C), PLGA/PLA polymers and TA microcrystals are colored as yellow and red, respectively.
