Help needed in preparation of nanoparticles

[sathish_1707]

Hi all... This is my second thread and the first one was sucessful with the help of you all. In the same topic i am in need of a help. I need to convert my macro particles of polymer to nano particle size with the help of microwave method or ultrasonic method since impurities are low. So anyone who knows about this nanoparticle conversion can share their ideas and methods with me.The polymers i need to convert are chitin, pectin, lignin, celloluse. Even if u know any other methods than the above mentioned two, jus share with me. Any help will be greatful to me. Thanking you.

I dont know much about microwave or ultrasonic particle fabrication but have you tried template synthesis? (using silica templates made via the Stober method) It's worked for me down to about 50 nm using such polymers.

if you are interested let me know as some of the fabrication steps are kinda lengthy and it's possible that this method may be useless for your application so i wont dive in with several pages of descriptions and methodologies until i know it may be useful.
