If you mean nanoemulsion then there aren't any particles - there will be liquid droplets dispersed in another liquid. The droplets may contain dissolved drug, not particulate drug.

In a nanoemulsion of lipids and active plant oils, the plant oils are encapsulated according to this article: https://www.dovepress.com/microfluidization-trends-in-the-development-of-nanodelivery-systems-an-peer-reviewed-fulltext-article-IJN

maybe youcan try lyophilization.

Dear,

To separate nano particle,

you can try centrifuge at different RPM in different solvent.

Also you can try dia-filtration / TFF system.

Or exclusion chromatography

Hi Prakash Rana ,

Yes, we have been doing centrifugation at various speeds. I wanted to know other ways that people had used which might be useful for our processing as well.

Thanks,
