If the particles are too small to be imaged, then perhaps indirect measurements such as Dynamic Light Scattering can be used to gain some information on the size/polydispersity of your samples at least~ If you have access to electron microscopes, TEM/SEM/AFM could also be useful.

Agnishwar Girigoswami

SEM would be best choice to image hydrogels.

Hanan Azzam

I agree with previous answers

You can be used advanced microscope such as TEM,SEM to image your formulation
