Production of pure drug nanocrystals and nano co-crystals ...

The traditional top-down processes offer reliable solutions for easy scaling-up, but present also disadvantages related to possible contaminations from the milling mediums, drug degradation, and longer time of processing. On the contrary, bottom-up processes offer an easy, greener alternative to the energy-dispersive top-down techniques.
