I prepared chitosan nanoparticles using an inonic gelation method. Who can tell me how I can prepare the best sample for an AFM test?
Dear Maryam,
There is a equipment called spin coater, it can be used to prepare the sample with uniform surface.
Enclosed an article which may help for your research

Maybe you can try to use our company's spin coater, you can do this easily by the spin coater
