The solid powder samples (pure LNS, pure CUR, CUR loaded S-SNEDDS and LNS-loaded S-SNEDDS) were examined using scanning electron microscope (Carl Zeiss EVO LS10; Cambridge, UK) to evaluate the effect of solidification on the adsorbent particle shape and detect the signs of incomplete solidification. Samples were fixed on stubs using double-sided adhesive carbon tape then coated with gold in a Q150R sputter coater unit (Quorum Technologies Ltd., East Sussex, UK) under vacuum for 60 s in an argon atmosphere (20 mA) [26 (link)].
