Can we use capillary zone electrophoresis (CZE or FSCE) to separate nanoparticles, please? Are there works in the literature on this topic?
What are the main difficulties to develop methodologies with CZE or FSCE for the separation of titanium dioxide nanoparticles or AuNPs, for example, please?

In any experiment, prediction or estimation of quantities is desirable. You need to estimate the rate of electrophoresis of nanoparticles. In the theoretical formula for determining electrophoresis, there is a factor for large particles equal to 6. For nanoparticles, it varies from 4 to 6 depending on the particle size and the thickness of the double layer.

Most TiO2's in the market (in particular, the powders) are not 'nano' but in the 300 - 350 nm region ('sub-micron' may be a better term..) and give milky suspensions. Because of the high density of TiO2 (~ 4200 kg/m3), then your TiO2 suspension would need to be clear (and not milky) to be
Dear Abdelkader BOUAZIZ
I thank you so much for your suggested articles.
Dear Yuri Mirgorod
I thank you so much for your attention. Would the CE be one of the best options in the separation of gold nanoparticles (AuNPs), please? Why?
Dear Alan F Rawle
I thank you so much for your answer. In fact, most TiO2's in the market are not nano and colloidal suspensions of Au are typically < 50 nm. I thank you for the suggestion of the ASTM 2490-09.
