Dear friends,
I've prepared alginate nanocapsules which are in distilled water. How can I dry them other than freeze-drying and spray-drying methods? In other word, in order to get a dried and powdered capsules what method you suggest?
My goal is to evaluate their stability in the simulated gastric fluid (SGF), So I need dried form of them. For example, according to a paper, 20-30 mg of microcapsules added to a glass tube containing SGF.

Dear Sepehr,
how about vacuum drying. Thsi is available on small scales, too and more often found at university departments than freeze drying and spray drying.
good luck,
Harald
