SEM and AFM analysis of the NPs and composite. a SEM analysis confirms the formation of spherical NPs with an average diameter of 190 nm. The median and mean particle diameters were determined to be 184 and 196 nm, respectively, and the standard deviation is 6.03 nm. b, c The formulation exhibits a smooth texture and is uniformly embedded with the NPs
