azadirachtin powder grinding procedure in wikipedia

Azadirachtin

Another recently described strategy is a poly(ε-caprolactone) (PCL) formulation constituting azadirachtin in a powder form using the spray-drying method (Forim et al., 2013). The nanometric particles were subjected to characterization in terms of size, shape, surface charge, and the encapsulation efficacy.
