Methods for grain size analysis of nanomedicines

As nanomedicines are developing fast in both academic and market areas, building up suitable methods for nanomedicine analysis with proper techniques is an important subject, requiring further research.  The techniques, which could be employed for grain size analysis of nanomedicines, were reviewed.  Several key techniques were discussed with their principles, scope of applications, advantages and defects.  Their applications to nanomedine analysis were discussed according to the properties of different nanomedicines, with the purpose of providing some suggestions for the control and administration of nanomedicines.
