Colloidal drug delivery systems

There are 8 points that I need to write about Colloidal drug delivery systems:

1. formulation
2. properties ( e.g. , particle size ) ,
3. excipients
4. why they are important ( e.g. , prolonged drug release or drug targeting to a specific tissue / organ )
5. preparation
6. uses
7. route of administration
8. examples of marketed products ( if possible )
   You are allowed to use figures and / or tables if needed
