Preparation of ROSCa nanoparticles. ROSCa nanoparticles were prepared in two steps. ROSCa powder was first subjected to dry milling using planetary ball mill (Pulverisette 7 Premium, Fritsch Co. Germany), in order to decrease the particles size to less than 20 µm. since the received raw material was analyzed for particle size and it was found 618 µm.
