    Th e advantage of dry milling the polymer prior to nanoparticle formation is that the surface characteristics of the polymer can be modi-fi ed without any chemical modifi cation. Planetary ball milling can be used to reduce particle size and in turn alter surface properties of materials by increas-ing surface area, porosity and shape
