On other hand, after ultrasound treatment of WPC–DIM nanoparticles, a considerably significant reduction ( p < 0.05) in the particle size of the WPC–DIM nanoparticles could be seen; for example, after ultrasound treatment for 5 min, the particle size of the untreated nanoparticle significantly dropped ( p < 0.05) from 265.96 to 255.86 nm.
